摘　　要：针对低品位砂岩铜矿的特点,进行了选矿试验研究。研究表明,加强细磨是提高指标的关键。在磨矿细度为-0.038mm占93%的条件下,经过三次粗选、一次扫选、两次精选的浮选流程,最终获得了铜精矿品位24.57%,回收率84.14%的浮选指标。According to the characteristics of a low grade sandstone copper ore,the tests of mineral processing are conducted.The research shows that the key to improving the flotation index is intensification fine grinding.The grinding fineness are 93% passing 0.038mm,after the flotation flowsheet of ＂triple roughing,once scavenging and twice cleaning＂,finally copper concentrate grade of 24.57% and the recovery of 84.14% are obtained.
