As water moves through a pyrite-bearing 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 pyrite-rich waste from mining operations can significantly increase the acidity of surface waters.
As a result, the metal value is preferably extracted directly from low grade ores through hydrometallurgical process. A detailed review of chalcopyrite deposits, production and consumption, mining, ore processing, steps involved in the pyrometallurgical and hydrometallurgical processing of copper as well as the dissolution kinetics and ...

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).

There are two basic types of extraction: surface and sub-surface (deep), each relying on a variety of techniques. Regardless of process, U.S. legislation requires operators to submit a plan for restoring the land and mitigating acid mine drainage before a permit is granted for mining operations.

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...
Estimates are that the Gateway Mine will shut down in 2013 or 2014. Since pyrite suns are found 300 feet underground new finds are unlikely to occur again without mining operations. The pyrite forms that have been found in China (also called pyrite suns) are very different from the well-known Illinois Pyrite Suns.

Chalcopyrite mineral mining process Chalcopyrite flotation. Chalcopyrite is our country is the most common copper ore, it both has protogenesis and hypergene, and flotability are good. In weak alkali in the pulp, brass ore can keep for a long time the natural flotability.
This process is hastened by the action of Acidithiobacillus bacteria which oxidize the pyrite to produce ferrous iron and sulfate. These reactions occur more rapidly when the pyrite is in fine crystals and dust, which is the form it takes in most mining operations. Acid drainage

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.
