摘要：××铜镍矿原矿中的镍、铜品位分别为0.39％、0.26％，该矿为原生硫化矿。其中主要金属矿物为磁黄铁矿、黄铜矿、镍黄铁矿、磁铁矿等；脉石矿物主要为滑石、蛇纹石、碳酸盐类矿物。如果在铜镍混选前没有预先脱除滑石，使得部分易浮滑石、蛇纹石进入到粗精矿中，容易造成中矿产率大、精选效率低、药剂用量大等现象，严重恶化铜镍浮选环境。铜镍精选作业中部分易浮的滑石、蛇纹石不容易被CMC抑制，造成铜镍分离后镍精矿中氧化镁含量偏高。为了降低滑石、蛇纹石对选别过程的影响，利用其浮游性好的特点，如果预先将其先选别出来，有可能降低这些矿物对流程的影响。

用翻译软件翻译的不太好。

copper-nickel mine ore in the nickel, copper grade of 0.39%, respectively, 0.26%, the mine for the primary sulfide ore. One of the main metal mineral pyrrhotite, chalcopyrite, pentlandite, magnetite, etc.; the main gangue mineral talc, serpentine, carbonate minerals. If the copper-nickel mixture without prior removal of pre-election talc, making easy to float part of talc, serpentine into coarse concentrate easily in mineral rate is high, select low efficiency, large pharmaceutical dosage phenomenon, serious deterioration of copper Nickel flotation environment. Copper-nickel operation in selected parts of the float Easy talc, serpentine is not easy to be CMC inhibited, resulting in nickel-copper-nickel concentrate after the separation of high concentrations of magnesium. In order to reduce the talc, serpentine sorting process on the impact of use of its good characteristics of planktonic, if its first pre-sorting out of these minerals have the potential to reduce the impact on the f
