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.
