Molybdenum trioxide (MoO3) is produced from the sulfide concentrate and used by the steel industry to produce steel alloys. An alternative and more attractive molybdenum product, molybdenum dioxide (MoO2), is produced using the Looping Sulfide Oxidation process. By examining the thermodynamics of the molybdenum-sulfur-oxygen system, the conditions necessary to selectively produce MoO2 over the trioxide have been identified. Under such conditions, oxygen, MoO3, or a mixture of the two can be used to convert the sulfide concentrate. Some of the resulting MoO2 is collected as final product, while some is oxidized to MoO3 and looped back to the conversion furnace to complete the cycle. A thermodynamic analysis of the reaction schemes and a discussion of the potential for energy capture are presented. The Looping Sulfide Oxidation process presents a paradigm shift in the production and consumption of molybdenum.
