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. The solution containing the dissolved precious metals ( pregnant solution ) continues percolating through the crushed ore until it reaches the liner at the bottom of the heap where it drains into a storage (pregnant solution) pond.
The copper ore usually contains a large amount of dirt, clay, and a variety of non-copper bearing minerals. The first step is to remove some of this waste material. This process is called concentrating and is usually done by the flotation method. 3 The ore is crushed in a series of cone crushers.
