Sodium Cyanide In Gold Mining

A sodium cyanide solution is commonly used to leach gold from ore. there are two types of leaching 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.
