摘　　要：四川省梭罗沟金矿氧化矿选矿过程中产生的氰化尾矿浆水呈较强碱性,COD、CN^-、Cu^+、Ni^(2+)、Zn^(2+)浓度超出《污水综合排放标准》(GB 8978-1996)一级标准限值,特别是CN^-超标515倍。通过加入不同剂量漂白粉,对氰化尾矿浆水进行破氰处理实验,使破氰尾矿浆澄清水呈中性,CN^-和各离子浓度均满足《污水综合排放标准》(GB 8978-1996)一级标准,最终得到针对处理梭罗沟金矿氰化尾矿浆水适合的漂白粉用量。Cyaniding tailings slurry form beneficiation process of oxidized ore from Suoluogou Goldmine in Sichuan Province displays strong alkalinity. The concentrations of COD,CN^-,Cu^＋,Ni^2＋,Zn^2＋exceed the first grade of Integrated Wastewater Discharge Standard（ GB8978-1996）. Especially,CN^-exceeds 515 times. After breaking cyanogen for treatment of cyaniding tailings slurry by adding different doses of bleaching powder to cyanide tailing water,make the waste water to be neutral. Moreover,the concentrations of CN^-and the other ions all meet the first grade of Integrated Wastewater Discharge Standard（ GB8978-1996）. Finally get the suitable bleaching powder dosage to cyanide tailing water of Suoluogou Goldmine.
