Gold Heap Leaching Process

Gold Heap Leaching Process

+

Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from lowgrade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the goldcontaining solution is leached.

Producing Copper Nature's Way: Bioleaching

+

In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals. It is the leaching of sulfide minerals that distinguishes bioleaching from conventional acid leaching wherein only oxidized minerals are leached. An associated process is biooxidation. This is the oxidation of sulfide minerals associated with but not .

flotation process, in mineral treatment and mining, process for concentrating the metalbearing mineral in an ore . Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.
