How does the Cyanide heap leaching process work

2021-4-2  The crushed ore is placed in large piles, called heaps, and sprayed with cyanide solution. The cyanide solution trickles down through the pile of crushed ore and dissolves the tiny gold particles away from the surrounding ore. The cyanide gold solution is collected at the bottom of the heap by a synthetic liner and sent to the mill.
