Heap Leaching of Gold and Silver Ores
 
10:03
HEAP LEACHING OF GOLD & SILVER ORES Heap leaching is the process to extract precious metals like gold, silver, copper etc, from their ore by placing them on a pad (a base) in a heap and sprinkling a leaching solvent, such as cyanide or acids, over the heap.. This process dissolves the metals and they collect at the bottom of the pad. The metal is then further processed. This methodology is mostly used for low-grade ores, and the basic processing steps involve crushing and sometime grinding.. The stages for heap leaching can be described as: 1. Ground Preparation and pad construction: Here the soil on a slightly sloping ground is compacted and covered by an impermeable pad (can be made of plastic). 2. Ore stacking: Then the crushed ore is stacked in the form of big heaps. Amount of fines is decreases as low as possible to improve permeability. 3. Then the leaching agent such as cyanide or acid is sprayed over the heap. 4. As, the reagent passes through the heap; the valuable metals get dissolved in it. 5. The solution containing metal is drained from the heap and collected in a pond and the solution is sent for subsequent process for metal recovery.. Is there any investors who are interested to cooperate for gold mining area in my village, actually typical of the material in my village is good proses by Heap Leaching Method process..

We had a customer send us some very high grade gold quartz ore which we recovered 1.310 troy ounces from only 300 lbs! We ran the quartz through our 1/2-1 ton per hour complete turnkey processor comprised of out jaw crusher, hammer mill, and shaker table modules. The system did a good job of crushing and pulverizing the ore, but the shaker table did a remarkable job of recovering lots of gold that was smaller than 325 mesh.

This expert team is currently working with the CCI mining group to scale the laboratory chemical extraction process to a high volume, high profit gold company featuring these groundbreaking new chemical gold extraction techniques. This dream team of mining and extraction engineers has over 85 years of combined experience working with metals and their scientific properties in high tech metallurgy laboratories around the world. The team members and scientists are all highly respected in the industry for testing metals and compounds to determine their weaknesses and potential breakdown points. This extensive experience has led to the development of the process of weakening and dislodging the ores and minerals that naturally adhere themselves to gold therefore liberating the gold into a purity level not before witnessed in chemical extraction. The Dome Rock Mines chemical gold extraction team has also pioneered the "Green" process in his chemical gold extraction by using chemicals that can be re-used over and over again without the need to dispose of highly toxic by products. This chemical gold extraction process is the most economical and environmentally friendly process of recovering gold at high levels of purity and high levels of profitability.

Electronic waste- The Future Gold Mines
 
03:18
#EwasteGold, #ElectronicWaste,#EGold A small Canadian company’s new way of extracting gold and other precious metals is showing big promise for the mining industry, and for efforts to deal with the growing problem of electronic waste. The CEO of Vancouver-based EnviroLeach Technologies says the new approach is also the biggest innovation for conventional gold mining in 150 years. “The advent of cyanide in the 1870’s was the biggest innovation in all of mining history, and this challenges that,” says Duane Nelson. “Our technology has equal-to or better leach kinetics than cyanide, and a much broader base of available ores and concentrates that it can be used on. So this is potentially a game changer for the mining sector.” New water-based extraction process aims to become an alternative to acid- and cyanide-based leaching. EnviroLeach’s new plant, a joint venture with electronics giant Jabil Inc., will open in December in Memphis, Tennessee. The 650,000 square foot plant will shred and pulverize discarded circuit boards and other electronic waste. Then, using proprietary technology, Jabil will extract gold and other precious metals from the e-waste to manufacture electronic components for Dell, Hewlett-Packard and other clients. Because it’s water-based and uses harmless ingredients, Nelson says the process is far more environmentally friendly than extraction by cyanide, hot acid digestion or other conventional methods. “You can put your hand in it,” says Nelson. “You can effectively drink the stuff,” he says, adding it’s also less expensive because the solution can be used repeatedly. Applying inorganic electro-chemistry research methods, Nelson says EnviroLeach’s team of 20 scientists “stumbled upon” the new technique. Ore concentrate or pulverized e-waste is mixed with ordinary water containing five ingredients. The solution is then pumped through cells of small, man-made diamond plates and then zapped with electricity. The gold and other precious metals separate and are extracted from the solution, which can be recharged and used again. With environmentalists pressuring governments to deal with the growing mountains of e-waste around the world, EnviroLeach and Jabil shareholders see huge profits in recycling the 50 million tonnes of e-waste dumped in landfills every year. But Nelson says the new process can also unlock riches for conventional mining. Unlike cyanide or hot acid digestion, Nelson says the new process doesn’t damage equipment. More importantly, it could be used in locations where cyanide is banned. “So there are hundreds of mines out there that could benefit from this technology,” he says. Does cheap, effective and environmentally safe mining sound too good to be true? Nelson has this response for the skeptics. “You know, cyanide sounded too good to be true in the 1800’s. Personal computers sounded too good to be true,” he says. “It’s innovation, and the mining sector has not been one of the most innovative sectors out there. “The environment will benefit, the mining sector will benefit, our shareholders will benefit. I think everyone is going to benefit from this.”

Donovan's Mill Part 1 "A Cyanide Wonder"
 
03:15
The first mill to use Cyanide to process the gold and silver from the extracted ore was Donavon's Mill. In 1890 it was bought out then expanded operating for over 30 years only to remain abandoned for nearly over a half of century. Today most of the mill is in tact which really adds to the value of its early mining history. I spent sometime adventuring the grounds which are surrounded by remnants of the past scattered across the hillside which also include cyanide tanks, assay office, blacksmith and machine shops. It is such a massive place with so much of the past left behind that I hope to eventually explore it on a paranormal level.
