Pyrite

PyriteIt often appears in the form of symbiosis with other minerals. It is the most widely distributed sulfide in the earth’s crust. It is formed under various geological conditions. Pyrite exists in a variety of stable fields due to the electronic configuration of Fe2, which enters the sulfur. The octahedral field composed of ions has a larger crystal field stabilizing energy, so pyrite can be formed and stabilized under various geological conditions.

In addition to pyrite crystal structure, chemical composition, surface structure and other factors that affect its suspension, many studies have shown that pyrite deposits, mineralization conditions, ore formation characteristics, ore structure and other factors also have an impact. The S/Fe ratio of each ore sample mostly varied in the range of 1.93~2.06. Generally speaking, the closer the S/Fe ratio is to the theoretical value, the better the floatability of pyrite. There is a certain limit to judge its floatability by simply using the ratio of pyrite, and the floatability of pyrite is related to the properties and chemical composition of the semiconductor.
