摘　　要：某黄金冶炼厂氰化尾矿处理工艺存在成本高,处理后尾矿总氰化合物含量波动较大等问题,试验采用低温焙烧破氰法进行氰化尾矿处理。结果表明:在焙烧温度325℃、焙烧时间40 min条件下,处理后尾矿含总氰化合物低于5 g/t,且可大幅降低氰化尾矿处理成本。该研究结果可为类似氰化尾矿破氰处理提供参考。The cyanide tailings treatment process in a gold smelter is costly and the total cyanide compound content in the tailings fluctuates significantly after treatment.In this experiment,a low-temperature roasting cyanide destruction method was used for cyanide tailings treatment.The results show that under the conditions of a roasting temperature of 325℃ and a roasting time of 40 min,the total cyanide compound content in the treated tailings is lower than 5 g/t,and the cost of cyanide tailings treatment can be significantly reduced.This study provides a reference for cyanide destruction treatment of similar cyanide tailings.
