Biomining - Wikipedia

Gold is frequently found in nature associated with minerals containing arsenic and pyrite.In the microbial leaching process A. ferrooxidans is able to solubilize the arsenopyrite minerals, and in the process releases gold: 2FeAsS[Au] + 7O 2 + 2H 2 O + H 2 SO 4 → Fe(SO 4) 3 + 2H 3 AsO 4 + [Au]. Biohydrometallurgy is an emerging trend in biomining in which commercial mining plants operate ...

Mining equipment for Pyrite processing

Gravity separation that can process pyrite is the separation that is according to the proportion difference between the pyrite and gangue which is associated with pyrite. The specific gravity of pyrite is higher and the specific gravity of gangue is lower. Through crushing and grinding, intergrowth structure in pyrite will be destroyed.

The mineral pyrite (FeS 2) and other sulfur containing minerals are common. Also common is the occurrence of these minerals in the geologic strata in the vicinity of coal seams. Mining coal inevitably involves exposing these pyritic materials to oxygen and water. In deep mines, these materials are exposed in the voids created by the mining process.
