The demand for gold recycling continues to increase and understanding the gold extraction process can help you decide what to do with your unwanted gold where you will find gold while gold coins and jewelry might seem like the only gold sources you can find this yellow precious metal in many other places because it is nontoxic for instance gold has historically been used in dental
The final category of gold mining is the processing of gold ore this method is largely becoming deprecated as the yield of gold is often very low and the environmental impact and costs of the operation are substantial the gold ore is finely crushed rock or earth containing trace amounts of gold which are extracted using a chemical process
The goldbearing minerals are then separated from other materials using a process called flotation a process called pressure oxidation is used to oxidize the goldbearing materials the oxidized material is mixed with a cyanide solution in large tanks inside the mill the gold dissolves in the
The process called gold cyanidation makes gold watersoluble and thus easier to isolate from the ore while using cyanide allows for the profitable extraction of gold from low quality ores it
These processes can all occur in holding pools in which the slurry after gold extraction is put into some chemical processes can also be used one of these is the cyanisorb process which is used at a mine near waihi this takes the slurry and reacts it at low ph forming hydrogen cyanide which can be converted back to cyanide ion for reuse
