how is molybdenum made into the ore
Molybdenum Molybdenum can often be found together with other ores, and is a byproduct of tungsten and copper mining The ore is roasted, formed into molybdenum oxide and then reduced into powdered metal for the production of rods, bars, sheets, plates, discs, powder or wiring Corrosionresistant Lubricates even under intense thermal conditionsMolybdenum processing, preparation of the ore for use in various products Molybdenum (Mo) is a white platinumlike 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 coefficientMolybdenum processing | Britannica
