  • How to Hunt for Pyrite | Our Pastimes

    Find Pyrite in sedimentary rocks such as shales. These shales, deposited in low oxygen conditions, tend to be dark in color and the pyrite crystals may be scattered or in big accumulations. In addition, pyrite crystals may replace fossils in shales. This type of pyrite is highly sought after by collectors.

  • How do pyrite and pyrrhotite damage building foundations ...

    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

    Thermal decomposition of pyrite into FeS (iron sulfide) and elemental sulfur starts at 550 øC; at around 700 øC pS2 is about 1 atm. Pyrite is a semiconductor material with band gap of 0.95 eV. During the early years of the 20th century, pyrite was used as a mineral detector in radio receivers, and is still used by 'crystal radio' hobbyists.
