Cyanide Use in Gold Mining Earthworks

Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metal impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.

How Cyanide Leaching is Used in Gold Mining

03/07/2015· Cyanide is used to extract gold from ore where it is spread throughout the ore in fine amounts. It is also usually done in conjunction with a process such as grinding, milling or a gravity separation that increases the surface area of the ore to expose as much gold as possible; this is done because the sodium cyanide solution has no effect on the gold during the extraction process if it
