FIELD: treatment of molybdenum cinders, concentrates, industrial products. SUBSTANCE: the starting products containing molybdenum trioxide are treated with a magnesium molybdenum solution having a concentration of 80-160 g/l at of 80-100 C for 20 min. The claimed process makes it possible to reduce the amount of MoO by 1.75-2 times at a degree of recovery of molybdenum from the starting products of 98% and to obtain highly concentrated molybdenum solutions thus facilitating their further treatment. EFFECT: improved process.
