摘　　要：某难选磷矿由于其脉石矿物与胶磷矿嵌布关系复杂,为了获得合格的磷精矿,用脱镁捕收剂BK425和脱铝捕收剂HA-1对原矿进行反浮选试验。当原矿磨矿细度为-74μm占70%时,采用反浮选脱镁(一次粗选、一次扫选)—反浮选脱铝(一次粗选、两次精选)全开路流程,可以获得P_2O_5品位31.14%,Al_2O_3含量2.60%,MgO含量0.92%,P_2O_5回收率79.54%的磷精矿。In order to obtain qualified phosphorus concentrate, the reverse-flotation test was carried out on the ore by using the magnesium-removing collector BK425 and the aluminum-removing collector HA-1. At the grinding fineness of 70% -74 jxm,the reverse-flotation of de-magnesium （roughing with one-stage of scavenging） and de- a-luminum （roughing with two-stage of scavenging） in a fully opened process obtained a phosphorus concentrate con-taining 31. 14% P2O5 , 2. 60% A1203 , and 0. 92% MgO , the P2O5 recovery being 79. 54% .
