Fe-Mo is an important noble ferroalloy. Commercial grade Fe-Mo contains between 60 % and 70 %.
Fe-Mo is a molybdenum-based ferroalloy, produced by alumino / silico thermic reduction from technical grade molybdenum trioxide (MoO3) or in induction / EAF furnaces from Mo containing scraps.
Molybdenite concentrates are roasted to form molybdic oxide. Technical grade molybdenum trioxide (MoO3), also known as roasted molybdenum concentrate (RMC), is the main raw material in the production of Fe-Mo. Roasting carry out conversion of concentrated molybdenite (molybdenum sulphide ore) into technical grade molybdenum trioxide. This oxide is mixed with iron oxide and aluminum and is reduced in an alumino-thermic reaction to produce ferro molybdenum. Fe-Mo is used in the production of different alloy steels.
