钨矿伴生硫化矿铜铋分选工艺试验

摘要

This paper studies the process test of copper-bismuth separation from sulfide minerals associated with tungsten ore by applying the combined process of gravity separation, flotation and gravity separation. The results of small closed-circuit test: the copper concentrate with the grade of 25.03 % and the recovery of 93.93 %; the bismuth loss rate in the copper concentrate is 7.08 %; the bismuth concentrate with the grade of 15.08 % and the recovery of 79.42 %; the copper loss rate in the bismuth concentrate is 1.84 %.%以江西某钨矿伴生硫化矿为试料,试验采用重-浮-重流程,铜铋分离试验采用优先浮选-浮铜抑铋工艺流程,小型闭路试验结果为:铜精矿品位为25.03％,回收率为93.93％,铜精矿中铋的损失率7.08％；铋精矿中铋品位15.08％,回收率为79.42％,铋精矿中铜的损失率1.84％.
