Extracting Gold HowStuffWorks
23/02/2009· Leaching dissolves the gold out of the ore using a chemical solvent. Themon solvent is cyanide, which mustbined with oxygen in a process known as carbon in pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

OverviewProcessEnvironmental ConcernsSee alsoExternal links
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, andpounds fromsing a series of chemical reactions that absorb specific minerals and re separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas in situ mining lacks these liners and pulls pregnant solution up to obtain the minerals. Heap leaching is widely used i
