Pyrite and pyrrhotite are minerals known as iron sulfides. When iron sulfides are exposed to water and oxygen, a series of chemical reactions breaks down the iron sulfides and forms new minerals called sulfates. These sulfates take up more space than the original iron sulfides. As they grow, the new sulfate minerals push against the surrounding rock, causing it to swell and

Cleansing pyrite with smoke, such as smudging, is probably the most effective way to cleanse pyrite. The name pyrite comes from the Greek work Puritēs which means of fire.

The mineral assemblage of the hydrothermal deposit is consistent with low temperature fluids (65ºC to 200ºC), pH 5 to 8.5 and Eh +0.1 to -0.6. Though, the mode of occurrence of pyrite and uranium minerals indicates that the pyrite is pre-uranium mineralisation, however some of the pyrite implies post mineralisation precipitation too.
