Homogeneous activation flotation method for copper-lead-zinc polymetallic sulfide ores

The invention relates to a homogeneous activation flotation method for copper-lead-zinc polymetallic sulfide ores, and belongs to the technical field of ore processing. The homogeneous activation flotation method for the copper-lead-zinc polymetallic sulfide ores is characterized in that the beneficiation process sequentially comprises the following steps: adding water as well as ammonium acetateand ammonium chloride reagent mother liquor which are prepared according to a certain proportion relation into the copper-lead-zinc polymetallic sulfide ores, grinding the ores until basic monomers ofthe copper-lead-zinc sulfide ores are dissociated, feeding the ores into a flotation machine for slurry mixing, adding copper sulfate as well as yellow powder and black powder in a certain proportionrelation, and carrying out conventional flotation to obtain copper-lead-zinc polymetallic sulfide ore mixed concentrate. According to the method disclosed by the invention, the ammonium acetate and the ammonium chloride cooper
