[Application]: Molybdenum dressing production line can be used for single or refractory molybdenum with complex properties ...ammonium molybdate from molybdenum concentrate. In this processing, the ore was heated in air at 750 C. The process converted the molybdenum sulphides to its oxides and evolved SO 2. Molybdenum oxides were then converted into sodium molybdate which was further changed into calcium molybdate and finally ammonium molybdate using different processes.
