Iron pyrite is mined in vein deposits and carbonate rock layers. It is also extracted from massive chalcopyrite and sphalerite deposits. Iron pyrite is abundant on the borders of Wisconsin, Iowa, and Minnesota. Commercial processing is done similar to mining iron ores. It is mostly mined today for its sulfur, copper and gold association.

One of the main sources of non-ferrous and precious metals is sulfide ores. This paper presents a review of the existing literature on the electrochemical properties of some of the most common industrial sulfides, such as pentlandite, chalcopyrite, sphalerite, galena, pyrrhotite, pyrite, etc. The study results of the surface redox transformations of minerals, galvanic effect, cathodic oxygen ...

At many mine sites the presence of pyrite causes a major environmental problem known as acid mine drainage. Bacteria contribute to the problem by utilizing an electron from ferrous iron retrieved from pyrite dissolution. The bacteria oxidize the ferrous iron to ferric iron, creating their energy source.

Iron Pyrite is a very abundant mineral found world wide. Pyrite is usually found associated with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well as in coal beds, and as a replacement mineral in fossils. Despite being nicknamed fool's gold, small quantities of gold are sometimes found associated with pyrite.

In subsequent years, Iron Mountain was also mined for gold, iron, zinc, and pyrite (iron sulfide); pyrite, a source of sulfur, was used to manufacture munitions and fertilizers and in petroleum refining. Mining exposed the minerals to water and air causing them to oxidize and release toxic constituents into the surrounding environment.

In fact, an important factor in the oxidation of pyrite and the generation of acid mine waters is that Fe 3 + is able to oxidise pyrite under anoxic subaqueous conditions at a much faster rate than does molecular oxygen (Espana, 2008). In other words, though oxygen is a primary oxidant, the ferric iron (Fe 3+) resulting from the oxidation of ...

Pyrite is a mineral composed of two elements, iron and sulfur. One atom of iron combines with two atoms of sulfur to create iron sulfide (FeS 2 ). Because of its appearance and presence in metamorphic/volcanic rocks which can contain gold, pyrite is known as "fool's gold." Pyrite has been mined in Virginia to obtain both iron and sulfur.
