Gold heap leaching. Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re-separates them after their division from other earth materials.he crushed ore is irrigated with a dilute alkaline cyanide solution.
