Abstract:
      Aiming at the problem that it is difficult to separate and recover copper-zinc sulfide ores after inhibition by sodium thioglycolate, this paper explores the floatability and related mechanism of butyl xanthate, copper sulfate and hydrogen peroxide on these sulfide ores after inhibition by sodium thioglycolate through pure mineral experiments. The results show that for the inhibited chalcopyrite, only the use of butyl xanthate can better restore its floatability, and the recovery rate can reach 91.01 %, while copper sulfate activation and hydrogen peroxide oxidation have little effect on further improving its floatability. The inhibited pyrite is more difficult to recover its floatability than chalcopyrite. It needs to be oxidized by hydrogen peroxide, and then butyl xanthate is added to effectively improve its floatability. The recovery rate can reach 90.22 %. The floatability of the inhibited sphalerite is the most difficult to recover, and it is difficult to recover its floatability regardless of hydrogen peroxide oxidation or copper sulfate activation, and its recovery rate is only less than 10 %.
