Most of the molybdenum concentrate is roasted to convert the sulfide to oxide, which is known as Technical Molybdic Oxide. Technical Oxide is the most common means of adding molybdenum to steel. Alternatively, a mixture of Technical Oxide and iron oxide can be reduced by aluminum in a thermite reaction to produce ferromolybdenum (also referred to as FeMo).
