Gold cyanidation
Gold cyanidation Gold cyanidation also known as the cyanide process or the MacArthur-Dingus process is a metallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex It is the most commonly used process for gold extraction1 Production of reagents for mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of cyanide used in other industrial processes such as plastics, adhesives, and pesticides2 Due to the highly poisonous nature of cyanide, the process is controversial and its usage is banned in a number of countries and territories Contents 1 History 11 Industrial process 2 Chemical reactions 3 Application 31 Effect of dissolved oxygen 32 Pre-aeration and ore washing 4 Recovery of gold from cyanide solutions 5 Cyanide remediation processes 6 Effects on the environment 7 Alternatives to cyanide 8 Legislation 9 References 10 External links History In 1783, Carl Wilhelm Scheele discovered that gold dissolved in aqueous solutions of c Gold cyanidation Click for more; https://www.turkaramamotoru.com/en/gold-cyanidation-6084.html There are excerpts from wikipedia on this article and video

Gold Mine-the way to extract gold
Gold extraction or recovery from its ores may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Ancient techniques of mining gold 1) placer mining- Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer mining techniques since the mid to late 20th century have generally only been the practice of artisan miners. 2) Hydraulic mining was used widely in the Californian gold rush, and involved breaking down alluvial deposits with high-pressure jets of water. Hard rock ores have formed the basis of the majority of commercial gold recovery operations since the middle of the 20th century where open pit and or sub-surface mining techniques are used. Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver (as electrum), or sometimes with mercury (as an amalgam). Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles embedded in other rocks. Ores in which gold occurs in chemical composition with other elements are comparatively rare. They include calaverite, sylvanite, nagyagite, petzite and krennerite. Gold refining and parting Gold parting is primarily the removing of silver from gold and therefore increasing the purity of gold. The parting of gold from silver has been done since ancient times starting in Lydia in the 6th century BC. Various techniques have been practised; salt cementation from ancient times, parting using distilled mineral acids from medieval times, and in modern times using chlorination using the Miller process and electrolysis using the Wohlwill process. How was gold extracted? In the old days it was extracted from mines with pick axes. Gold nuggets were dug from veins of crystal quartz that often included silver, mercury, and lead. Today most of that ore has been tapped, and new methods are employed. The gold is no longer even visible to the naked eye--it is dust, scattered throughout an ore body in a zone. Strip mined ore is piled on slanted V shaped sheets of plastic where it is sprayed with a solution of cyanide. The cyanide bonds with the gold which settles into a pond. The pond is drained, the rich ore scooped up and further processed to recover the gold. A profitable ore body may contain as little as 0.02 oz of gold per ton of ore. I have toured several gold mining operations in northern Nevada, and have staked claims for other mines there.

Belknap Indian Reservation. Since that time the Zortman Landusky Gold Mine operation closed when the Pegasus Gold Corporation filed for Bankrupsy leaving Montana with yet another massive Superfund Site and dangerous ground water pollution problem. The Pegasus Gold Corporation (a Candadian Company) obtained the land without royalty through the use of the 1872 mining law and left the US tax payers footing the bill for a massive cleanup which will never end.

Heap Leaching of Gold and Silver Ores
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..

URBAN MINING! Recovering gold, copper, precious metals from PCB's without chemicals
We are excited to post this video and show you all our progress on processing printed circuit boards (PCB's) for gold, copper and other metals with our hammer mill and shaker table. We have the ability to take whole boards, crush them, and run them on our shaker table. We are still in the experimental stage but we have high hopes to have a complete system ready to sell soon. I should clarify that we can't recover all the gold from the boards, but at the end of the video we do have free metallic gold in the gold pan. Our goal is to take whole boards and concentrate out the valuables (metals) from the non-values (fiberglass, plastic, etc). The free gold can easily be removed, melted, and sold directly to a gold buyer, leaving the concentrates, which are much more valuable that the boards themselves. The remaining gold is plated onto other metals. This cannot be mechanically separated, but using the hammer mill and shaker table it can be concentrated into a salable product. The #2 and #3 hole outputs can be sold to a refiner and let them deal with all the chemicals and refining process. For most people its too complicated, dangerous, expensive, etc. to separate out the different metals in the concentrates. As a side note the free gold per pound recovered from the ~20 pounds of boards equates to 1 troy ounce per ton of boards. This would be considered very high grade gold ore for any miner. The PCB's also have loads of copper, tin, lead, plated gold, etc that is added value on top of that 1 oz/ton free gold recovered. Stay tuned and please email or call if you are interested in any of our equipment.

Ban Cyanide (BM with Mandarin subtitle)
More than 1000 days has passed since RAGM, the gold factory started making money by extracting dirty gold which use life-threatening cyanide compounds. No doubt the mine bosses are laughing to their banks. For they care not about the Raub residents, particularly those from Bukit Koman, who live in agony and fear. Previously healthy people are falling ill. Many testified to unbearable itchiness, severe rashes, persistent cough, and other worrying symptoms. Yet more painful is that complaints and appeals made to the authorities have fallen on deaf ears. They did nothing to prove that the mines are safe. The government allows this doubtful polluting factory to run 24-7 non-stop. On the other hand, objecting residents are ill-treated with harassment and misinformation for the last 3 years. All these have to stop. We are not against profit-making businesses. It just happened that this gold factory operates in a very unethical way that pollutes the environment and harms our life. Despite the odds, we must struggle for our rights to live a healthy life without fear. Let us gather for Himpunan Hijau Raub on Sept 2, 2012 at 2.00pm for the struggle against dirty, cyanide-using goldmines. Together we fight for a greener future! Life Above Profit! No Dirty Gold!
