我们采用油酸与轻质柴油按2:1配成混合剂(一般混合搅拌后静置约30分钟)浮选白钨,所得的白钨精矿含三氧化钨由47%提高至70%左右。所用的原料是黑钨产物经干燥后,由强磁性磁选机选入非磁性区内,再分别以优先浮选选钼、铜、铋后的尾矿。原料中含大量黑钨矿、白钨矿、褐铁矿、泡铋矿、锡石、石英等,并有少量黄铁矿、毒砂、方 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, limonite, bismuthinite, cassiterite, quartz, etc., and a small amount of pyrite, arsenopyrite, square
