The Process Test of Copper-Bismuth Separation from Sulfide Minerals Associated With Tungsten Ore

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 %.
