摘　　要：铜硫钨多金属矿浮选尾矿水回用于铜硫浮选时,严重影响铜硫精矿的选矿指标.研究结果表明,钨浮选尾矿水经简单处理后回用,在铜浮选作业加入新型调整剂CW、在钨浮选作业加入对黄铁矿和磁黄铁矿捕收能力较弱的新型钨捕收剂TM,可获得铜精矿品位18.36%Cu、回收率76.67%的指标,其选别指标接近于用自来水的指标.When the flotation tailing water of Cu-S-W polymetallic ore is reused to copper-sulfur flotation processes,the technical index of copper concentrate and sulfur concentrate would be seriously affected. Experimental result shows that,the copper concentrate with a grade of 18.36 % Cu at a recovery of 76.67% has got in small closed-circuit test using recycling water, through simple pretreatment of tailing water of tungsten flotation and adding special regulator CW in copper flotation and adopting new collector TM which with weak capacity in collecting pyrite and pyrrhotite in tungsten flotation. The result is equivalent with the performance without using tailing water.
