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.

Pyrite Minerals Education Coalition

Pyrite. Commonly called fool’s gold, pyrite is the Earth’s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

Pyrite Earth Sciences Museum University of Waterloo

Pyrite seldom forms in fresh-water environments. The formation of pyrite crystals depends mainly on the iron content of the sediment. The process of pyrite formation in sediments results from the action of bacteria, which reduce sulphate ions (dissolved in the pore water) to sulphide. If there is iron present, iron sulphide crystals begin to grow.
