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.

2021-6-25 To make the gold heap leaching process successful, the heap leaching material must have good permeability so that the cyanide solution can evenly pass through the ore pile. Most ores need to be crushed to 25.4mm or finer before granulation in order to expose the gold contained in the ore and improve the gold recovery rate.
