Cyanide In Crusher. Ore processing consists of the following stages crushing and grinding of the ore addition of process water generally decanted from the tailings pond to form a slurry addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution.
Cyanide Use in Gold Mining - Earthworks
How is cyanide used in 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.
