Abstract: Primary molybdenum and symbiotic molybdenum are the main source of molybdenum resource, this paper discusses beneficiation methods of single molybdenum and copper-molybdenum ore, coarse grinding roughing-regrinding and reconcentration is the typical beneficiation process of primary molybdenum, bulk flotation-separation of copper and molybdenum is the main method of separation for copper-molybdenum ore, namely rough copper-molybdenum concentrate can be obtained firstly, and then copper and molybdenum can be separated from rough copper-molybdenum concentrate, and introduces the beneficiation process of major molybdenum concentrator from home and abroad.
