柿竹园矿石中黑钨矿的柱浮选半工业试验

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。

Semi-industrial Column Flotation Test on Wolframite Revocer from Shizhuyuan Ore

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.
