摘要
在ｐＨ值７．５～８的条件下，研究了疏水絮凝浮选新工艺处理难选细粒氧化锑工业矿石。研究证明，当细粒氧化锑浮选在给矿品位为１．９７％，氧化率为８７％时，可获得精矿品位为１７％～１９％，回收率为７０％～７４％的氧化锑精矿，这与现在工厂所用摇床选收比较，精矿品位提高了５％，回收率增加约５０％。
In this paper a study of new flotation technology of hydrophobic flocculation for treatingthe industrial ores of refraetory fine antimony oxide minerals has been carried out.Testingresults under the condition of pH value 7.5～8.0 reveal that a concentrate with a grade of17%～19% Sb and recovery of 70%～74% can be obtained from a fine-grained antimony ox-ide feed assaying l.97%Sb and oxidation rate over 87%.As compared with that of shakingtackle in use,the grade is raised by 5%and recovery is increased by 50%.
