摘要：在研究福建省某钼矿厂难选低品位钼中矿性质基础之上，通过高效捕收剂、组合抑制剂的优化配伍，结合浮选与重选技术，实现了该钼矿物的高效综合利用，得出合理的浮选流程结构与药剂制度和最佳的重选工艺参数.浮选钼精矿产品品位为45.14%，回收率达到64.7%，钼浮选尾矿由重选可分别获得硫精矿和重选钼精矿，其中重选钼精矿产品品位为3.17%，回收率达到17.2%，整个流程中钼总回收率达到81.9%.

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%.

Key words: low-grade, middlings of molybdenum, flotation, gravity separation
