Abstract:The metals which can be comprehensively recovered from a gold cyanide leaching tailings mine in Jiangxi Province are lead and zinc with their grades are 2.25% and 0.71% respectively. The oxidation rate of lead is high, and the particle size of tailings minerals is fine. According to the characteristics of the tailings, the scheme of "sodium hypochlorite pretreatment-lead-zinc preferential flotation process" is adopted in the experimental，which obtains lead concentrate with lead grade of 54.53% and zinc grade of 5.12%， zinc concentrate with zinc grade of 46.52% and lead grade of 2.37%，the test index is good and comprehensive utilization rate of metals is high , moreover, the test process is simple and easy to implement and the reagent system is economical and reasonable. it provides a technical basis for the comprehensive utilization of the tailings resources.D11 is a new collector for lead minerals developed according to the properties of cyanide tailings, which is a white powdery solid and easily soluble in water, and the collection ability and selectivity for lead minerals are good.
