本文研究了一种活化氧化锑矿物浮选的新方法。按该法构想,选择了四种性质相近的药剂,即:LZL、RYR、KXK及AW,分别处理氧化锑矿物,并以油酸作捕收剂进行浮选试验。结果表明:这些药剂均能很好地活化氧化锑矿物,但对石英不起作用;人工混合矿浮选分离效果良好,当给矿中含锑由2.83%富集到30％时,回收率超过85％。 In this paper, a new method of activating flotation of antimony oxide minerals has been studied. According to the idea of ​​this law, four kinds of agents of similar nature, namely LZL, RYR, KXK and AW, were selected and antimony oxide minerals were treated respectively. Oleic acid was used as collector for flotation test. The results show that these agents can activate antimony oxide minerals well, but have no effect on quartz. The artificial mixed ore flotation separation effect is good. When the content of antimony in ore is enriched from 2.83% to 30%, the recovery rate exceeds 85%.
