Pyrite types are generally divided according to the main sulfur minerals they contain. They are roughly divided into five categories: natural sulfur ore, pyrite ore, magnetite ore, coal-based pyrite ore and polymetallic associated pyrite ore. Sometimes, for the sake of mineral processing technology, pyrite ore is subdivided into silicate type and carbonate type according to the different gangue minerals it contains. Sulfur ore is one of the important raw material minerals in the chemical industry, mainly used to make sulfuric acid and then produce fertilizers. It is also an important raw material for chemical, pesticide, pharmaceutical, rubber, metallurgy, papermaking, petroleum and other industrial sectors. Especially in industry, it is used to manufacture and smoke agents. Pyrite grinding, flotation and classification are used in friction materials to adjust friction properties and high-temperature wear resistance and improve adhesion properties at high temperatures, which has a good effect.
