Heap Leaching Mining Fundamentals

Heap leaching is an industrial mining process of separating precious metals, copper, and other minerals, from ores. It involves a series of chemical processes, through which the mineral ores are piled into the form of a heap, and a leach solution is spread over the ore surface to leach metal from

What is the role of cyanide in mining MiningFacts

Cyanide, in the form of a very dilute sodium cyanide solution, is used to dissolve and separate gold from ore. [3] The process used to extract gold using cyanide was developed in Scotland in 1887, and was first used in large scale commercial mining by the New Zealand Crown Mines Company at Karangahake in 1889.

Heap leaching

Process Of Gold Mining Yanacocha Peru The Largest

Heap leaching is the process to extract precious metals like gold, silver, copper and uranium from their ore by placing them on a pad (a base) in a heap and sprinkling a leaching solvent, such as cyanide or acids, over the heap. This process dissolves the metals and they collect at the bottom of the pad.
