摘要
福建某浮选尾矿金品位为0.23g/t,通过采用GTD-80离心选矿机在离心力90G、反冲洗水压力80kPa、排矿时间30分钟条件下进行粗选,获得金品位为7.45g/t,回收率8.30%的粗精矿,粗精矿经LY2100×1050摇床精选获得金精矿品位16.69g/t,总回收率6.44%的指标,年增效益120余万元。
The gold grade of a flotation tailings in Fujian is 0.23g/t.By using a GTD-80 centrifugal concentrator under conditions of centrifugal force of 90G,backwash water pressure of 80kPa,and ore discharge time of 30 minutes,a coarse concentrate with a gold grade of 7.45g/t and a recovery rate of 8.30% was obtained.The coarse concentrate was treated with LY2100 × The 1050 shaker selection obtained a gold concentrate grade of 16.69g/t,with a total recovery rate of 6.44%,and an annual increase of over 1.2 million yuan in benefits.
