Separation Process of Chalcopyrite, Galenite, Sphalerite and Pyrite. 1. The Separation of Chalcopyrite and Pyrite Method It depends on the ore property, including the following two methods: Preferential Flotation: This method is suitable for dense lump ores.
As water moves through a pyritebearing rock, the pyrite''s iron component may be oxidized, releasing its sulfur to form sulfuric acid. In natural settings this is seldom a concern, but pyriterich waste from mining operations can significantly increase the acidity of surface waters.

Metal Mining and the Environment (Booklet), American Geosciences Institute Provides basic information about the mining cycle, from exploration for economic mineral deposits to mine closure. The booklet discusses the environmental aspects of metal mining and illustrates the ways science and technology assist in preventing or reducing ...
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 pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).
The pyrite from the coal waste was collected in the city of Treviso/SC, Brazil. After comminution processes, the average particle size determined by a Cilas 1064 laser granulometer, was reduced to μm. Methods. To evaluate the purity of "in natura" pyrite, the pyrite was characterized by:
