  • Pyrite Mineral Uses and PropertiesGeology

    Pyrite is a brass-yellow mineral with a bright metallic luster. It has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide mineral. It forms at high and low temperatures and occurs usually in small quantities in igneous metamorphic and sedimentary rocks worldwide. Pyrite is so common that many geologists would

The test work determined the Bond ball mill work index and hardness parameters related to semi-autogenous mill grinding (SAG) and high pressure grinding rolls (HPGR) crushing. The grindability test results indicated that the sample is moderately hard for grinding by ball mills but is very hard for milling by SAG mills.
