摘要: 针对柿竹园多金属矿回收黑钨矿时浮选机浮选工艺存在的流程复杂、精矿品位较低问题,采用旋流-静态微泡浮选柱在现场进行了黑钨矿柱浮选半工业试验。试验结果表明,旋流-静态微泡浮选柱通过1次粗选、2次精选,所获黑钨精矿的品位为44.39%、回收率为86.82%,与现场1粗5精3扫浮选机生产相比,在省去3次扫选和减少3次精选的情况下,黑钨精矿品位提高11.45个百分点,同时回收率提高3.52个百分点。

Abstract: For the complex technological flowsheet for the recovery of the wolframite of Shizhuyuan polymetallic ore,the lower grade wolframite concentrates,the process of cyclonic-static micro-bubble flotation column is adopted on-site to make the semi-industiral column flotatin tests of wolframite ore. The test results showed that the wolframite concentrates containing WO3 of 44.39% and recovery rate of 86.82% are obtained through the closed-circuit of one stage roughing and two stage cleanings by using three cyclonic-static micro-bubble flotation columns. Compared with closed-circuit of one stage roughing five stage cleanings and three stage scavengings by using the flotation machines,the wolframite concentrates containing WO3 increased 11.45 percentage,and the recovery increased 3.52 percentage,meanwhile three roughings and three cleaings were cut.
