Iron pyrite is a naturally pure and hugely useful ore of iron, finding applications in areas as diverse as photovoltaic cells, brake pads and as a glass colourant. African Pegmatite is a leading supplier of iron pyrite, with the ability to provide the material in a range of grind sizes suited to any operational need.

Pyrite is a brass-yellow mineral with a bright metallic luster. It has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide mineral. It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide. Pyrite is so common that many geologists would consider it to be a ubiquitous mineral.
pyrite, also called iron pyrite or fool's gold, a naturally occurring iron disulfide mineral. The name comes from the Greek word pyr, "fire," because pyrite emits sparks when struck by metal. Pyrite is called fool's gold; to the novice its …
Iron sulfide scale has several forms; pyrrhotite (FeS), troilite (FeS), pyrite (FeS), greigite (FeS), and mackninawite (FeS). Pyrite, which has good thermal stability, tends to …
Crystalline pyrite did not function as an electron donor. In contrast, an active denitrifying microbial community developed upon addition of iron sulfide. The dominant process in the iron sulfide amended bioreactor was identified, based upon stoichiometric calculations, as the oxidation of sulfide to sulfate, at the expense of nitrate or nitrite.
Iron sulfide minerals have many applications; for example, greigite, a ferrimagnetic mineral, can be used as a paleomagnetic indicator 1, 2 and for treating hyperthermia associated with cancer...
Pyrite is an iron sulfide (FeS 2) mineral with pale brass-yellow fast tarnishing color (Fig. 1.43). The pale brass-yellow collar and metallic luster gives a superficial resemblance to gold (fool's …
In the present study, the potential of two iron sulfide minerals (pyrite and iron sulfide) to function as electron donors for microbial nitrate reduction was investigated in a bioreactor under anoxic, freshwater conditions. Crystalline pyrite did not function as an electron donor.
Pyrite has been mined for its sulfur content, however. During WWII, sulfur was in demand as a strategic chemical and North American native sulfur mines were drying up. A sulfide deposit near Ducktown, Tennessee contained …
The mineral pyrite or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron (II) disulfide). Pyrite is considered the most common form of sulfide minerals. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames …
Pyrite is an iron sulfide (FeS 2) mineral with pale brass-yellow fast tarnishing color (Fig. 1.43). The pale brass-yellow collar and metallic luster gives a superficial resemblance to gold (fool's gold). The crystal system is isometric (cubic) with indistinct cleavage with penetration and contact twinning. The mineral shows very uneven to ...
Iron sulfide scale has several forms; pyrrhotite (FeS), troilite (FeS), pyrite (FeS), greigite (FeS), and mackninawite (FeS). Pyrite, which has good thermal stability, tends to deposit at shallower places downhole and is inert to acid. Other iron sulfides react with acids. Thermal stable species are much harder to be removed by acids.

This fine specimen has large striated cubic crystals of pyrite (iron sulphide). Discover more. Glossary of geoscience terms. Geoscience (also known as earth sciences and geology) is the study of the Earth and includes all non-living parts of our environment, and everything below the Earth's surface. Here are some common geoscience terms explained.
Pyrite forms in sedimentary rocks in oxygen-poor environments in the presence of iron and sulfur. These are usually organic environments, such as coal and black shale, where decaying organic material consumes oxygen and …
Pyrophoric iron sulfide is formed by the action of corrosive sulfur compounds on iron and steel in process facilities, particularly in vessels, storage tanks, and pipeline scraper traps. If such equipment has contained asphalt, aromatic tars, sour crude, high-sulfur fuel oil, aromatic gases, and similar products, the potential exists for the formation of black- or brownish-colored …

Hydrogen sulfide, often present in crude oil tankers, can react with rust to form various sulfides including mackinawite (FeS), greigite (Fe {sub 3}S {sub 4}), and pyrite (FeS {sub 2}). The tendency for these compounds to react with oxygen in air to form potentially explosive mixtures depends upon their morphology and the environmental conditions.
Pyrite has been mined for its sulfur content, however. During WWII, sulfur was in demand as a strategic chemical and North American native sulfur mines were drying up. A sulfide deposit near Ducktown, Tennessee contained commercially valuable deposits of pyrite and other sulfides such as pyrrhotite and pentlandite and produced the needed sulfur as well as iron and other metals. …
