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.

112· Pyrite forms in a reducing environment with a continuous supply of sulfate and iron, as well as in the presence of easily decomposable organic matter. The major factors that determine the rate of pyrite formation include carbon-to-sulfur ratio, availability of iron, and oxidation potential (Evangelou, 2000).

4. Sulfide Ore Processing and Iron Production Iron sulfide ores require special treatment due to their sulfur content. Traditional iron ores, such as hematite and magnetite, are relatively straightforward to process, whereas sulfide ores like pyrite and pyrrhotite need to undergo additional steps to separate sulfur from iron. This often involves roasting, where the sulfur is …
