四川某铜镍矿含铜0.35％、含镍0.78％,脉石以滑石、蛇纹石类易浮、易泥化的富镁硅酸盐矿物为主,生产现场由于不能对脉石进行有效抑制,只能采用预先脱泥工艺,不仅造成铜镍损失严重,且流程复杂.采用新型有机抑制剂WY-03后,获得了镍精矿镍品位6.36％、镍回收率82.02％,铜精矿铜品位23.97％、铜回收率72.96％的优异指标.%A copper nickel ore in Sichuan contains 0.35 ％ copper and 0.78 ％ nickel.The main gangues are talc,serpentine these magnesium rich silicate minerals,which are easy flotation and sludge.In the field of production,because the gangue cannot be effectively inhibited,only the pre-desliming process was adopted,that not only caused serious loss of copper and nickel but also was complex process.Mter the new organic inhibitor WY-03 was used,the result was ideal and the nickel concentrate and the copper concentrate were obtained,the nickel concentrate whose grade is 6.36％ and recovery rate is 82.02％,the copper concentrate whose grade is 23.97％ and recovery rate is 72.96％.
