molybdenum processing, preparation of the ore for use in various products. Molybdenum (Mo) is a white platinum-like metal with a melting point of 2,610 °C (4,730 °F). In its pure state, it is tough and ductile and is characterized by moderate hardness, high thermal conductivity, high resistance to corrosion, and a low expansion coefficient.
