摘要：

Given the comprehensive utilization problems of tailings in gold smelting, the behavior of iron in the roasting process is discussed in this paper and the optimal conditions are obtained through reduction roasting of the cyanide tailings. The results show that the amount of iron in the cyanide tailings is 35.55%, but the amount of magnetic iron is only 0.28% of all the iron. An iron ore concentrate with iron grade of 52.81% and recovery of only 20.43% can be obtained by high-intensity magnetic separation to the cyanide tailings. After being reduction roasted at the conditions of 750℃,addition volume of pulverized coal 6%,1h and water cooling, the magnetic iron reached up to 84.83%. Have low-intensity magnetic separation on the roasted tailing, the iron grade of the iron ore concentrate is 64.39% and the recovery is 84.67%.
