摘　　要：对湖北某低品位复杂铜矿进行了浮选试验研究,探索了磨矿细度、药剂种类、药剂用量等条件对浮选指标的影响。结果表明,磨矿细度-0.074 mm粒级占75.2%,采用一粗三精三扫闭路浮选流程,选择丁基黄药、Z⁃200、乙硫氮作为组合捕收剂,次氯酸钙与石灰复配作为调整剂,在原矿铜品位0.42%条件下,获得了铜精矿铜品位12.15%、回收率85.05%的技术指标。Flotation tests were carried out for a low⁃grade complex copper ore from Hubei province.The influences of grinding fineness,reagent type and dosage on flotation indices were investigated.A closed⁃circuit flotation flowsheet consisting of one stage of roughing,three stages of cleaning and three stages of scavenging was adopted to process this kind of ore with Cu grade of feed ore of 0.42%,grinding fineness of-0.074 mm 75.2%,butyl xanthate combined with Z⁃200 and sodium diethyldithiocarbamate as collectors,calcium hypochlorite combined with lime as regulator.As a result,a copper concentrate with Cu grade of 12.15%and recovery of 85.05%was recovered.
