Ancient mining techniques go well back into our history – well back into ourprehistory, in fact. As we progressed through the Stone Age, with more and more sophisticated tools and weapons being designed and developed, so too,our need for more and better raw materials for these implements. Stone and flint led to copper, then bronze, gold, silver, iron… all in the name of progress, war, technology, vanity or greed. In fact, it’s ironic (pun intended) that the substance prized and even mined by our ancient ancestors for some of the earliest stone tools and weapons – flint – was later a hindrance encountered by Classical miners – who were in many cases also Classical minors – in gold mining galleries described by Pliny the Elder in the 1st century AD as “thought to be the hardest thing that exists, except greed for gold, which is the most stubborn of all things.

#iitutor #Chemistry #HistoricalUsesOfMetals https://www.iitutor.com To a large extent, cultural achievements have been defined in terms of the materials used during particular periods of human history such as the Stone Age, Copper Age (5000-3000 BC), Bronze Age (3000-1000 BC) and Iron Age (from 1000 BC). Until approximately 14 000 years ago the main materials used by humans were wood, stone, bone, shells and plant products. Archaeological evidence suggests that humans first used metals around 14 000 years ago. Gold, silver and copper can be found as almost pure metals in various parts of the world and were initially used by humans to make jewellery, ornaments and tools. The ability of these metals to be beaten and bent into various shapes and their relative scarcity made them prized possessions. Most metals however, are chemically combined with other elements forming naturally occurring compounds called minerals. At the beginning of the nineteenth century, Humphry Davy used electrolytic procedures to extract active metals such as potassium, magnesium and calcium from their salts. In turn, these active metals can be used to extract other metals from their compounds. For example, titanium can be extracted from titanium chloride by heating it with magnesium or sodium metal. Pure titanium was not isolated till 1910 although impure forms had been discovered a century before. As increasingly sophisticated methods of extracting metals from their mineral ores were discovered, new metals such as iron, and lead became available. Another important discovery was that the properties of metals could be significantly altered by combining them with other elements to form alloys, such as bronze, brass and steel. The Age of Copper began about 8000 years ago in the Middle East. Native copper, which was harder than gold, was mined and used for simple tools such as pins and hooks as well as for jewellery. The blue and green copper ores found in the mountains were used for decorative purposes. By 6000 years ago humans had discovered ways of converting these copper minerals into metallic copper by a process called smelting. This process involved strongly heating the crushed ore in a reducing environment rich in carbon (charcoal) and low in oxygen. Bellows were used to blow air into the furnace to cause the charcoal to burn and raise the temperature and produce carbon monoxide, which created a reducing atmosphere. Under these conditions the heat energy supplied was sufficient to break the ionic bonds in the lattice to release the metal. The copper particles that formed in the reaction were mixed with a glassy slag formed from the quartz present in the ore body. Further improvements in furnace design over the next 1000 years produced sufficiently high temperatures so that the copper remained as a liquid, which could be run off and cast into tools such as spears, arrowheads and axe heads. Copper was also used for kitchen utensils such as plates and cups. Its high thermal conductivity made it useful for cooking pots. Its high lustre when polished made copper sheets useful as mirrors. Bronze is an alloy of copper and other metals such as arsenic or tin. Bronze was first discovered about 5000 years ago when impure copper ores containing arsenic and lead minerals were smelted. The copper that formed had different physical properties due to the presence of these other metals. Arsenic bronze was eventually replaced by tin bronze as tin bronze was not as brittle as arsenic bronze. Tin bronze was used to make cutting tools such as knives and axes and these were superior to copper as they maintained a sharper edge that could be readily resharpened. By 4000 years ago an extensive trade in tin bronze had developed between Europe and the Middle East. Its rarity made it even more prized than gold. The high nickel content of the meteoric iron resulted in an alloy that was corrosion resistant. High temperature smelters in which iron ore was mixed with charcoal were required to produce the metal from iron ore. The charcoal burns in the blast of air to form carbon monoxide, which reduces the iron ore to iron. The earliest iron samples were spongy masses containing impurities that were often difficult to remove. Controlling the amount of carbon in the iron was a major problem. Blacksmiths developed a method of hammering the iron at red heat to squeeze out the solid impurities as well as burn off the carbon. In all these examples, pure iron was never obtained. Instead, various types of iron alloys such as carbon-steels were formed. Unlike meteoric iron, these carbon steels tended to readily corrode (rust) unless other metals such as nickel or chromium were added to the mixture. Iron and steel replaced bronze and other copper alloys in many applications because of the superior strength and hardness of iron alloys. CB3111 http://youtu.be/nfmsynWPyrk

Sure, we’ve come across ore carts and trammers before while exploring at abandoned mines. However, finding an intact underground mine train parked with the ore carts still hooked up to the trammer (what miners call the electric locomotive) is something that I have never seen before or since. I’ll give away some of the secrets of the upcoming videos by saying that there is a second part to this train just a short distance farther down the track. I wonder if the operator of the trammer/locomotive felt a twinge of sadness when it was parked underground for the last time? I mentioned in the description and comments of the last video that I would talk more about the history and geology of the abandoned mine in this description. The below is a translation from Italian to English and the translation is not perfect. However, it conveys the relevant information. So, quoting directly, here you go.. “The Buca della Vena Mine (formerly Stazzema Mine) was part of the 15th-16th century Vene Ferralis, although it is believed that works were held there already during the Medicean period. Work restarted between 1850 and 1860, and in 1938 the Pignone of Florence company began excavating. Since 1957, the SIMA company (subsidiary of EDEM) continued to work regularly in the tunnel searching mixed mineral barite-pyrite until 1990. The field is described as a mineral body almost unique with barite, pyrite and iron oxides of good quality. It is oriented NNE/SSW, in the contact zone between shale Unit Fornovolasco, white dolomite and grezzoni. Considerable scientific interest was aroused by the discovery of rare or unique in the world mineralogical species. Minerals mainly extracted are: - barite used for chemicals, pharmaceuticals, petroleum industry and as nuclear power plants insulation - pyrite for chemicals and iron and steel - iron oxides for steel products” Although the mine being explored in this video apparently dates back to the Medicean period, I passed ancient workings while pushing up the canyon walls that date back to the Romans and even the Etruscans. In other words, the iron ore deposits here have not exactly been a secret for thousands of years. The section of the Buca della Vena Mine featured in this video hosted very dark rock and huge open chambers. So, even with multiple lights, it was a struggle to fully illuminate it. While there are certainly some even more impressive pillars and massive chambers to come, the rock is lighter and so that should not be much of an issue going forward. ***** All of these videos are uploaded in HD, so adjust those settings to ramp up the quality! It really does make a difference. You can see the gear that I use for mine exploring here: https://bit.ly/2wqcBDD You can click here for my full playlist of abandoned mines: https://goo.gl/TEKq9L Thanks for watching! ***** Growing up in California’s “Gold Rush Country” made it easy to take all of the history around us for granted. However, abandoned mine sites have a lot working against them – nature, vandals, scrappers and various government agencies… The old prospectors and miners that used to roam our lonely mountains and toil away deep underground are disappearing quickly as well. These losses finally caught our attention and we felt compelled to make an effort to document as many of the ghost towns and abandoned mines that we could before that colorful niche of our history is gone forever. But, you know what? We enjoy doing it! This is exploring history firsthand – bushwhacking down steep canyons and over rough mountains, figuring out the techniques the miners used and the equipment they worked with, seeing the innovations they came up with, discovering lost mines that no one has been in for a century, wandering through ghost towns where the only sound is the wind... These journeys allow a feeling of connection to a time when the world was a very different place. And I’d love to think that in some small way we are paying tribute to those hardy miners that worked these mines before we were even born. So, yes, in short, we are adit addicts… I hope you’ll join us on these adventures! #ExploringAbandonedMines #MineExploring #AbandonedMines #UndergroundMineExploring

Minnesota's first iron ore mine—the Soudan Mine—opened in 1882. Operations went underground by 1892 since the ore body continued deep into the ground.The mine's value was in the special kind of ore it produced. The ore's high oxygen content was used to make high-quality steel in open-hearth furnaces. When technology changed, the ore from the mine was no longer needed. Low-cost ores of the Mesabi Range took over, and Soudan Mine closed in 1962. Today, you can explore the last level that the miners worked.

Mining iron ore on Old School Runescape. This is done on a full world for the fastest re-spawn times. If done correctly this is the fastest mining experience up to approximately level 75. The method simply involves dropping the ore as you turn. If you click on a rock to mine it then quickly drop some ores and re-click the rock without losing time/chance to mine the rock. I usually just drop one ore between rocks except the third rock where I sometimes drop more (if I have made mistakes and not dropped ores for example) as there is a spare bit of time before the re-spawn (explained below). You can drop as many as you want to fit in without losing time. *Alternative*: If you want to be more lazy you can also just mine the three rocks, drop 3 ores at once while waiting for the rock to re-spawn, and then continue, but it can be quite easy to lose a little bit of time doing this if you don't drop fast enough and re-click. On a full world the time taken between getting two ores in your inventory is 3 game ticks, unless of course you fail to mine the rock immediately, but this doesn't happen after about level 60. However, it takes 11 game ticks (about 6.6-6.7 seconds) to actually mine all three rather than 9 ticks, as even on a full world the rocks don't spawn quickly enough as can be seen in the video. Assuming you kept getting an 11 tick round the xp/hour would be: (3600/6.7)*105, which is ~56k/hr. However, there are a low amount of full population worlds at the moment and limited locations, so you may get crashed et cetera, which will lower this value. I am using a rune pickaxe. Sorry that the quality is not that good. I use Arch Linux OS and used the recordMyDesktop package to record, which isn't really ideal for recording RS, but I didn't want to bother messing about with another screencast program.

I do not own the copyright to this movie and this is being posted here under YouTube's Guidelines for informational and teaching purposes.

It took me the better part of a day to explore this abandoned mine and I didn’t even cover the whole site. If you look at a satellite view of this mine (the coordinates are in the description in the first video), you can see that there are workings over the hill behind the mill (rhyming unintentional) that I did not visit. I have no reason to believe that this part of the mine would be dramatically different than that which we have already seen, but still, it speaks to the massive size of the Santa Lucia Mine. Of course, those workings over the hill are more remote and the more remote a mine is, the better the discoveries to be made there in our experience. So, who knows what might be back there? I hope that what I was trying to explain with the layout of the adits when I was underground made sense. Essentially, what I was saying is that with the older workings the miners burrowed their way through the mountain and, I would imagine, extracted a fair amount of ore via the room and pillar method or through enormous stopes. As technology advanced and open pit (also called open cast) mining became more economical, the miners just hammered straight through the mountain and removed a significant part of it. In doing so, they rammed right through the older workings, causing these drifts to cave in and to be filled with rubble. Regrettably, the two adits we found that led to workings that had not been smashed through by the open pit were both totally inaccessible (the one in the first video was flooded to the top and the one in this video was caved right at the portal). Given the number of muckers as well as the trammer, ore carts and other mining equipment, I would imagine those workings were pretty extensive and it would be interesting to see how this deposit of ore was mined (as well as, of course, to see what sort of artifacts the miners might have left behind). I also hope that the way the mill functioned makes more sense now after having had a chance to see the second video with the first half of the mill. I unknowingly explored the mill backwards when I visited as I visited the second half of the ore processing facility in the first video and the first half of the mill in the second video. That even sounds confusing to me and I am the one that wrote it. So, hopefully, all of you followed that. ***** All of these videos are uploaded in HD, so adjust those settings to ramp up the quality! It really does make a difference.

We explore a iron and tin mine in east Cornwall, the mine which was last worked around 1912. There are 2 accessable adits in the hillside, this is the top level, less extensive than the lower one, but still a interesting explore. Both levels are connected by a incline skipway shaft and a small winze. - Please drop by my new facebook page and give me a like: https://www.facebook.com/CornishMineE... - Important Note: We don't post the real names of the mines featured in our videos, to protect the sites and to stop others with less experience putting themselves in danger. If you know this place, please don't mention it by name or location. Our team consists of ex miners, cavers and mine rescue, every trip is taken with caution and callouts made to other members of where we are underground. Please do not put yourself at risk or others by entering these abandonded mines.

Hulett Unloaders were once a common sight along the shores of Lake Erie. They unloaded the ore ships coming down from Lake Superior and the Iron Range. These Huletts in Conneaut, Ohio, belonged to the Bessemer & Lake Erie Railroad. the B&LE hauled coal north and iron ore south to Pittsburgh-area steel mills. As a bonus, some footage of the Hulett unloaders in Lackawanna, New York is included at the end. This was taken in 1925. Here is Wikipedia's description of the history and operation of Hulett unloaders: "The Hulett was an ore unloader that was widely used on the Great Lakes of North America. It was unsuited to tidewater ports because it could not adjust for rising and falling tides, although one was used in New York City. History The Hulett was invented by George Hulett of Ohio in the late 19th century; he received a patent for his invention in 1898. The first working machine was built the following year at Conneaut Harbor in Conneaut, Ohio. It was successful, and many more were built along the Great Lakes, especially the southern shore of Lake Erie to unload boats full of taconite from the iron mines near Lake Superior. Substantial improvements were later made on the design by Samuel T. Wellman. The Hulett machine revolutionized iron ore shipment on the Great Lakes. Previous methods of unloading lake freighters, involving hoists and buckets and much hand labor, cost approximately 18¢/ton. Unloading with Huletts cost only 5¢/ton. Unloading only took 5–10 hours, as opposed to days for previous methods. Lake boats changed to accommodate the Hulett unloader, and became much larger, doubling in length and quadrupling in capacity. By 1913, 54 Hulett machines were in service. Two were built at Lake Superior (unloading coal) and five at Gary, Indiana, but the vast majority were along the shores of Lake Erie. The additional unloading capacity they brought helped permit a greater than doubling of the ore traffic in the 1900–1912 period. A total of approximately 75 Huletts were built. One was installed in New York City to unload garbage. The lake's Huletts were used until about 1992, when self-unloading boats were standard on the American side of the lake. All have since been scrapped. In 1999, only six remained, the group of four at Whiskey Island in Cleveland, Ohio the oldest. Another set was used unloading barges of coal in South Chicago until 2002 and were demolished in the Spring of 2010. In spite of the Cleveland machines being on the National Register of Historic Places and designated as a Historic Mechanical Engineering Landmark, they were demolished in 2000 by the Cleveland Port Authority to enable development of the underlying land. The Port Authority disassembled and retained two Huletts, to enable their reconstruction at another site, but the reconstruction has not yet happened. Operation The electrically powered Hulett unloader rode on two parallel tracks along the docks, one near the edge and one further back, ordinarily with four railroad tracks in between. Steel towers, riding on wheeled trucks, supported girders that spanned the railroad tracks. Along these girders ran a carriage which could move toward or away from the dock face. This in turn carried a large walking beam which could be raised or lowered; at the dock end of this was a vertical column with a large scoop bucket on the end. A parallel beam was mounted halfway down this column to keep the column vertical as it was raised or lowered. The machine's operator, stationed in the vertical beam above the bucket for maximum cargo visibility, could spin the beam at any angle. The scoop bucket was lowered into the ship's hold, closed to capture a quantity of ore, raised, and moved back toward the dock. The workmen who operated the Hulett uploaders were known as Ore Hogs. To reduce the required motion of the carriage, a moving receiving hopper ran between the main girders. It was moved to the front for the main bucket to discharge its load, and then moved back to dump it into a waiting railroad car, or out onto a cantilever frame at the back to dump the load onto a stockpile. The Hulett could move along the dock to align with the holds on an ore boat. When the hold was almost empty, the Hulett could not finish the job itself. Workmen entered the hold and shoveled the remaining ore into the Hulett's bucket. In a later development, a wheeled excavator was chained to the Hulett's bucket and lowered into the hold to fill the Hulett." Two ships appear in this video: The B. F. AFFLECK, built 1927, laid up 1979, scrapped 1986. Coal-fired boilers, triple expansion engine, 2200 IHP. The COL. E. M. YOUNG, built 1905 as the HOOVER & MASON, renamed E. M. YOUNG in 1929, renamed SPARKMAN D. FOSTER in 1956, scrapped 1963. Coal-fired boilers, quadruple-expansion engine, 1750 IHP. As seen in this video, she was equipped with a self-unloading boom from 1928 to 1953.

►► http://www.goldextractionprocess.com Smelting of rare antique gold. The process of refining gold to remove any impurities that may be found intermixed with the noble metal is an ancient practice that has long been employed by diverse cultures. One of the earliest gold refining equipments employed by ancient metallurgists was the blast furnace – by then a rudimentary structure built with clay, stone, or roughly hewn rocks which were fed with wood or an assortment of biofuels derived from the dried fecal matter of animals. The blast furnace was used in tandem with the crucible, one of the oldest and perhaps still widely used metallurgical instruments to this day. With the methods of gold refining being perfected through the decades, even rustic objects such as clay pots and later on, cast iron equipment were employed in the quest for purer and finer examples of gold.

I invented the Bow Blower, a combination of the bow drill and forge blower to make a device that can force air into a fire while being easy to construct from commonly occurring natural materials using only primitive technology. I began by fanning a fire with a piece of bark to increase its temperature. It is this basic principle I improved on throughout the project. Next, I made a rotary fan from two pieces of bark that slot together at right angles to each other to form a simple 4 bladed paddle wheel about 20 cm in diameter and 5 cm tall. The blades of the fan were not angled and were designed only to throw air outwards away from the axle when spun. The rotor of the fan was made by splitting a stick two ways so it formed 4 prongs. The fan was then inserted into the prongs and the end lashed to hold it in place. Spinning the fan rotor back and forth between the palms of the hands fanned the fire. But only some of the wind generated by the fan reached the fire. The rest of it was blowing in other directions, effectively being wasted. So I built a fan housing from unfired clay to direct the air flow into the fire. This was basically an upturned pot with a hole in the top, a spout coming out of the side. The housing was about 25 cm wide and 8 cm tall. The hole in the top and the spout were both about 6 cm in diameter so that the air coming in roughly equalled the air coming out. The base of the fan rotor sat in a wooden socket placed in the ground to make it spin easier and the top of the rotor protruded from the hole in the top of the housing. Now when the fan spun, air entered the hole in the top of the housing and exited the spout in the side. Importantly, it doesn’t matter which way the fan spins, air always goes into the inlet and out the spout. Air is thrown out towards the walls of the housing and can only leave through the spout while the vacuum in the centre sucks new air into the housing through the inlet. A separate clay pipe called a tuyere was made to fit over the spout to direct air into the coals. This was done because the pipe that touches the fire can melt away so it’s better to make this part replaceable. Instead of making a large wheel and belt assembly to step up the speed of rotation, I opted for a 75 cm long bow. I made a frame to hold the rotor in place consisting of two stakes hammered into the ground with a socketed cross bar lashed on to hold the top of the rotor. I made bark fibre cordage and tied the end to a stick. I then looped the cord around the rotor and held the other end in the same hand holding the stick. I then pushed and pulled the bow causing the rotor to spin rapidly, forcing air into the fire. I made a simple mud furnace for the blower. Then I collected orange iron bacteria from the creek (iron oxide), mixed it with charcoal powder (carbon to reduce oxide to metal) and wood ash (flux to lower the melting point) and formed it into a cylindrical brick. I filled the furnace with charcoal, put the ore brick in and commenced firing. The ore brick melted and produced slag with tiny, 1mm sized specs of iron through it. My intent was not so much to make iron but to show that the furnace can reach a fairly high temperature using this blower. A taller furnace called a bloomery was generally used in ancient times to produce usable quantities of iron and consumed more charcoal, ore and labour. This device produces a blast of air with each stroke of the bow regardless of whether it is pushed or pulled. The bow makes it possible to operate the blower without using a complicated belt and wheel assembly used in traditional forge blowers. There is a brief pause at the end of each stroke where the fan stops to rotate in the other direction, but this is effectively no different to the intermittent blast of a double acting bellows of Europe or box bellows of Asia. The materials used (wood, bark, bark fibre and clay) are readily available on most continents. No leather, valves or precisely fitted piston gaskets are required as with other types of bellows. The cords for this device wear out often so a number of back up cords should be kept handy for quick replacement. In summary, this is an easy to make device that solves the problem of supplying forced combustion air required for high temperature furnaces and forges.

Hi guys, the journey into the depths of a very large scale mine in the Walhalla gold belt. If you've ever wondered just how far we go into the earth and have a spare hour I highly recommend a watch."Darkness surrounds you, the only source of light available to you is secured to your forehead. It is cold, there are puddles underfoot and slime on the walls, the trek forwards seems endless, yet you have dropped over one hundred meters from the dense bush above to penetrate deep into this subterranean labyrinth. You hear creaks and unidentifiable sounds echoing through the stone chamber as you steadily make your way forwards through the quartz lined walls, underneath the stulls and over rusty pickaxes. Your light beam hits a reef and you see flickers of minerals, perhaps gold, most likely just iron pyrite, it adds to the eerie mystical charm of the underground chamber and increase your sense of adventure. You’re in an underground maze of tunnels with the nearest exit made via a rope and an ascension rig. Does this sound like a dream, or a nightmare? Meet the blokes who do this for fun, who thrive on the adrenaline and the fear, who wake up with shivers at the thought of abseiling down mine shafts, penetrating their depths and exploring their vast passages in search of the unknown. The gold around your ring finger; the oil in your engine; the metal in your coins; the ancient pickaxe in your local museum; what do these have in common? Each was, at some point in time, discovered in a mine. The Victorian Historical Mineshaft Chasers follow the myths left by long gone miners, plot their escapades via geological topographical maps, and follow the markings left by the men who cut these mountains open. The puddles can be waist high, the dangers are numerous, challenging and very real, but the sense of accomplishment and the addiction to the thrill is what keeps them diving. Made up of amateur history buffs, prospectors, miners, photographers, and men from all walks of life, The Victorian Historical Mine shaft Chasers Inc host members aged from their young teen years to upwards of 45. A shared wealth of knowledge and experience keeps them safe, and allows them to continue to pass on the information gleamed from both verbal and experienced lessons, and their contribution to the preservation of times past is a bright glimmer in a society which is slowly allowing history to fade. Welcome to the mines, we hope you enjoy the dive… "

One thousand years ago, as Europe languished in the dark ages; China occupied a position at the very forefront of technology and innovation. While the European Renaissance occupies a firm place the historical understanding of most people, its Chinese counterpart has received comparatively little attention. The innovations of Leonardo da Vinci, Columbus and Renoir have been explored in countless texts and films, yet most commentators have glossed over the achievements of Su Song, the legendary figure who had spearheaded the Chinese Renaissance five hundred years earlier. This programme sets out to redress the historical imbalance. For the first time, we reveal the remarkable story of how China created a myriad of ingenious devices including cosmic machines able to collect data on the stars, hydraulic hammers, water-controlled clocks and even paper. We discover that ancient China was an industrial superpower, armed with devices such as 'heaven carts' able to drill down deep underground, geared milling machines and mass production plants powered by water. Incredibly, unlike the ancient Egyptians, the Chinese developed their inventions with an eye for safety. Sophisticated mining props were designed to prevent cave-ins, while ancient 'carburettors' were employed to control volatile natural gas. Indeed, Chinese inventors are even credited with designing the world's first earthquake detector. We embark upon an epic journey across all of China, meeting the leading historians and model-makers who have kept tales of ancient China alive. We visit a reconstruction of an ancient Chinese iron furnace, where we unravel insights into how the Chinese created a forty-ton iron artefact five centuries before the West discovered cast-iron technology. Most impressively of all, we meet the leading clay expert Professor Ye Hongming, who has spent a lifetime seeking to discover the secrets of ancient China's vast terracotta army. This pioneering documentary seeks to lift the centuries-old veil on China's greatest inventions, revealing how many of the West's modern-day inventions owe an extraordinary debt to ancient China's greatest minds. .

The importance attached to low sulfur iron is demonstrated by the consistently higher prices paid for the iron of Sweden, Russia, and Spain from the 16th to 18th centuries. Today sulfur is no longer a problem. The modern remedy is the addition of manganese. But, the operator must know how much sulfur is in the iron because at least five times as much manganese must be added to neutralize it. Some historic irons display manganese levels, but most are well below the level needed to neutralize sulfur (Rostoker Bronson , p. 21). The major effect of silicon is to promote the formation of grey iron. Grey iron is less brittle and easier to finish than white iron. It is preferred for casting purposes for this reason. Turner (, pp. 192--197) reported that silicon also reduces shrinkage and the formation of blowholes, lowering the number of bad castings. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). Ore is a rock containing a metal or mineral. Themercially valuable substance is extracted from the ore. Known and worked since... Another, minor, source of iron ores are magmatic accumulations in layered intrusions which contain a typically titanium-bearing magnetite often with vanadium. These ores form a niche market, with specialty smelters used to recover the

THANKS FOR 100,000 VIEWS! I am sorry about the music; I will be honest, it sounded fine to me editing so I didn't lower the volume any more. My 1-99 Mining guide including: P2P fastest, P2P money/xp, F2P money/xp. This one took a while to put together so I hope I haven't disappointed you. Please check out the rest of the description for links to important videos. For anyone wondering, when this video was made Granite tick manipulating was not very popular (nor did I know about it), so that is why it isn't here. P2P fastest: 2:27 P2P money/xp: 6:57 F2P money/xp: 14:41 F2P runite mining: 22:51 All Mining Guides (inlcudes motherlode, iron, granite): https://www.youtube.com/playlist?list=PLFVR6vvoeBehPKbtn8csy4YDanplYUtab 99 Mining Challenge Review/Advice: https://www.youtube.com/watch?v=I1Xx4pAI518 Thanks for watching.
