某含铜磁铁矿石选铜试验

摘要

针对某低铜磁铁矿石开展了选铜试验。结果表明：在磨矿细度为－0．074 mm 占75．43％的情况下，以水玻璃＋六偏磷酸钠为脉石矿物的抑制剂，MA 为铜矿物的捕收剂，MIBC 为起泡剂，采用1粗2精2扫闭路浮选流程处理矿石，可获得铜品位为19．51％、铜回收率为69．20％的铜精矿。%Copper selection experiment was conducted on a low copper content magnetite ore.The results show that:at the grinding fineness of 75.43% passing 0.074 mm,sodium silicate and sodium hexametaphosphate as gangue inhibitor,MA as copper collector,MIBC as frother,via one roughing-two cleaning -two scavenging closed circuit flotation process,copper concentrate with 19.51% copper and recovery of 69.20% was obtained.
