Processing Gold Ores Using Heap Leach

Processing Gold Ores Using Heap Leach

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.
