我們采用油酸与輕質柴油按2:1配成混合剂(一般混合搅拌后靜置約30分鐘)浮选白鎢,所得的白鎢精矿含三氧化鎢由47%提高至70%左右。所用的原料是黑鎢产物經干燥后,由强磁性磁选机选入非磁性区內,再分別以优先浮选选钼、銅、鉍后的尾矿。原料中含大量黑鎢矿、白鎢矿、褐鉄矿、泡鉍矿、錫石、石英等,並有少量黄铁矿、毒砂、方鉛矿、輝鉍矿、閃鋅矿和輝钼矿。当鹽矿細度达到一60目100%时,白鎢单体分离达95%以上。所采用的药剂制度列于麦1。浮选給矿粒度—60目100%时,所获得精矿产品
We use oleic acid and light diesel at a ratio of 2: 1 to form a mixture (usually mixed and let stand for about 30 minutes) to collect white tungsten, resulting in scheelite containing tungsten trioxide from 47% to 70% . The raw material used is that after the black tungsten product is dried, it is selected into a non-magnetic zone by a ferromagnetic magnetic separator, and then the tailings after selecting molybdenum, copper and bismuth are preferentially flotated respectively. The raw material contains a large amount of wolframite, scheelite, tanzanite, bismuthinite, cassiterite, quartz, etc., and a small amount of pyrite, arsenopyrite, galena, bismuthinite, sphalerite and molybdenite . When the salt mine fineness reached a 60 mesh 100%, montmorillonite isolated more than 95%. The drug system used is listed in Mai 1. Flotation to the ore size -60 mesh 100%, obtained concentrate products
