Oct 13 2004& 0183;& 32;Peruvians probably the biggest exporters of pyrite to the USA and Europe give most of their pyrite a bath in HCl before export. I don't know the concentration they use or time taken. You could try the acid sold everywhere for use in swimming pools - In the USA that is often a mixture of HCl and phosphoric acid. Cheers Alfredo
Apr 30 2018& 0183;& 32;Pyrite was once used as a source of sulfur but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous and therefore is used as an ore of gold in gold-bearing localities. Pyrite was polished by the Native Americans in the early times and used as mirrors.预计阅读时间：3

Pentlandite is an important ore of nickel. However it does not produce good crystals and is generally only found in massive form. It is commonly associated with other sulfides such as pyrite chalcopyrite and pyrrhotite in basic igneous rock intrusions. These sulfide ore bodies are probably produced through magmatic segregation.
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.
established in Australia specifically to mine pyrite ore i.e. the Brukunga Mine in SA and the King Mine at Norseman in WA. In the late 1960’s a large source of sulphur became available as the result of refining ‘sour gas’ produced from natural gas fields discovered in Canada. Both pyrite

Name Confusion: Pyrite vs. Marcasite. Until the early 1800s many people used the word “marcasite” and its foreign equivalents collectively for pyrite marcasite and other yellow iron sulfide minerals. It was not until 1845 that marcasite was recognized as an orthorhombic iron sulfide and different from pyrite.

Pyrite is popular for its crystal habit hardness streak lustre and brittleness. Its composition is of iron disulphide having a pale brass-yellow colour. The name “pyrite” is derived from the Greek words “pyrites lithos” which mean “stone which strikes fire” in allusion to the sparking produced when iron is struck by lump of pyrite.
As a natural reduction mineral pyrite FeS₂ was combined with biochar by simply ball milling technology to synthesize FeS₂ biochar composite BM-FeS₂ BC and applied for the removal of hexavalent chromium Cr VI in aqueous solution.

Gravity separation is often used for processing medium particle disseminated pyrite ore with good separation performances. The specific gravity of pyrite is higher which can reach to 4.95.2. Floatation method is mainly for fine disseminated pyrite ore.
Historically pyrite was used commercially as a source of sulfur particularly for the production of sulfuric acid but today sulfur is largely collected as a by-product of petroleum processing. Because of the availability of much better sources of iron pyrite is not generally used as an iron ore.

An aerial tramway conveyed the ore a distance of approximately 4 miles from IMM to Matheson. The pyrite ore was stockpiled onsite and then transported to processing plants in California and Washington via the railroad.
