摘　　要：安徽某高硫低品位铜矿硫品位41.30%、铜品位0.53%,易氧化,选矿指标不稳定。为了改善铜硫分离效果,研究了磨矿细度、药剂种类和药剂用量等对浮选指标的影响。结果表明,磨矿细度-0.074 mm粒级占83.88%,采用一粗二精二扫闭路浮选流程,以CaO+Na_(2)S为组合抑制剂、Z-200为捕收剂、2#油为起泡剂,获得了铜品位15.27%、回收率80.96%的技术指标。试验结果可为高硫低品位铜矿浮选回收铜提供参考。A low-grade high-sulfur copper ore from Anhui Province has a sulfur grade of 41.30%and a copper grade of 0.53%.It is difficult to control the flotation index of this easy-to-oxidize ore.To improve the Cu/S separation effect,the influence of grinding fineness,reagent type and reagent dosage on copper flotation index was investigated.A closed-circuitflotation process including one stage of roughing,two stages of cleaning and two stages of scavenging was adopted to treat the ore with a grinding fineness of 83.88%-0.074 mm,with CaO and Na_(2)S as a combined depressant,Z-200 as the collector and terpenic oil as the frother.It is found that a copper concentrate grading 15.27%Cu at 80.96%recovery can be obtained.This experimental study can provide a reference for flotation separation of copper from low-grade high-sulfur copper ore.
