Iron pyrite is a fairly common mineral and is mined or extracted globally for its many industrial uses such as extraction of the sulphur for sulphur dioxide or sulphuric acid and also as an ore for iron. It oxidises readily making it easy to extract the component minerals but care must be taken as this also makes it quite combustible.

2016527The contamination of sulfur emanating from pyrrhotite in magnetite concentrates has been a problem in iron ore processing. This study utilied froth flotation to float pyrrhotite away from magnetite using collectors of xanthate and dixanthogen. It was found that xanthate or dixanthogen alone could not achieve selective separation between pyrrhotite and magnetite in flotation.

Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO 3 ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite. On addition of a collector the pyrite is rendered floatable enabling froth flotation to achieve a concentrate rich in pyrite and tailings
