摘要
某铜锌矿石含铜2.86%、锌1.30%、硫29.15%、金1.00g/t、银39.16g/t,试验研究表明,在磨矿细度-74μm占80%的条件下,采用部分混合—优先浮选流程粗选,混合粗精矿再磨后进行铜、锌分离浮选,最终可获得含铜25.91%、回收率为85.23%的铜精矿,含锌32.14%、回收率为83.40%的锌精矿,含硫50.98%、回收率为82.21%的硫精矿。
Some copper-zinc ore is tested to contain 2.86% Cu, 1.30% Zn, 29.15% S, 1.00 g/t Au and 39.16 g/t Ag. The experimental research indicates, under the condition of -74um grinding fineness being 80%, the process of roughing by partial mixing-preferential flotation, grinding of mixed rough concentrate, followed by separation flotation of copper and zinc is adopted to obtain copper concentrate with 25.91% Cu and copper recovery of 85.23%, zinc concentrate with 32.14% Zn and zinc recovery of 83.40%, and sulfur concentrate with 50.98% S and sulfur recovery of 82.21%.
