摘　　要：为解决四川会理锌矿选矿废水循环利用的问题,对自然降淀、混凝沉淀、吸附分离等处理方法分别进行了小试,并将处理后的选矿废水进行闭路试验。结果表明,混凝沉淀—活性炭吸附法处理选矿废水可有效去除COD,回用作选矿水不会影响选矿指标,可实现选矿厂废水的零排放。Experiments of gravitational and coagulating sedimentation and activated carbon adsorbing separation etc. were conducted and crossed-circuit circulation of treated wastewater was run at practical condition for the mineral concentration wastewater reuse in Huili Zinc Mine. The results showed that COD could be removed effectively by coagulating sedimentation and activated carbon adsorbing process, the treated wastewater could be reused for mineral concentration or discharge directly. So called zero discharge could be realized by this way.
