How does the Cyanide heap leaching process work and what,
02-04-2021· Cyanide leach mining is a type of gold mining that uses cyanide to extract gold from the surrounding rock. First, the rock that contains gold (the ore) is dug out of the ground, leaving behind a large open pit. Then, the ore is crushed into small pieces. The crushed ore is placed in large piles, called heaps, and sprayed with cyanide solution.
