| Abstract: | The sample of low-grade molybdenum ore comes from a molybdenum mine plant in Fujian Province.As for the high oxidation rate of the molybdenum ore,it is very difficult to produce it through the technology of the plant currently.By using efficient collector and mixed inhibitor,it can reach the efficient comprehensive utilization of this middlings by flotation and gravity separation.Then a reasonable structure and pharmacy system and the optimal technological parameters of gravity separation have been selected.The concentrate grade of molybdenum in closed-circuit test reached 45.14% and the recovery reached 64.7%.The sulfur concentrate and molybdenum concentrate can be obtained by gravity separation.The grade of the concentrations from the gravity separation of tailings of flotation reached 3.17% and the recovery reached 17.2%.The total recovery of molybdenite reached 81.9%. |
