Study on Flotation Process of a Molybdenum Mine in Anhui
The molybdenum grade of a molybdenum ore in Anhui is 0.348%.Molybdenum mainly ex-ists in the form of molybdenum sulfide,and the distribution rate is 97.71%.In order to provide the basis for the development and utilization of ore,the beneficiation test is carried out.The results show that the ore is ground to 70%of-0.074 mm.After one roughing,two scavenging,eight cleaning and three stage regrinding(regrinding 1 is-0.043 mm 80%,regrinding 2 is-0.043 mm 89%,regrinding 3 is-0.043 mm 93%)closed-circuit flotation with PM-3 as collector,the molybdenum concentrate with molybdenum grade of 57.11%and recovery of 91.2%is finally obtained.The research results provide a basis for the flotation process design of the molybdenum ore.
