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.

2024524· As it heats, the sulfur in the pyrite will begin to oxidize and separate from the iron. The oxygen in the air will react with the sulfur, forming sulfur dioxide gas which will bubble up and out of the oven. This roasting process will melt the iron in the pyrite into a slag that can be easily separated from the roasted pyrite ore.
