某氰化尾渣综合利用实验

    Test of Comprehensive Recovery of Cyanide Residue

    • 摘要: 这是一篇矿物加工工程领域的论文。某金矿的全泥氰化尾渣含金0.45 g/t,金主要以硫化物包裹金形式存在,且主要分布于+0.037 mm粒级中。经过分级预处理后,对+0.037 mm矿样,在磨矿细度-0.037 mm 15%条件下,采用一次粗选两次扫选三次精选闭路实验流程,获得含金21.25 g/t,作业回收率72.27%的金精矿产品。

       

      Abstract: This is an essay in the field of mineral processing engineering. Cyanide tailings of a gold mine contain gold 0.45 g/t, and the gold mainly exists in the form of vulcanized gold and is mainly distributed in coarse particles. After the classification treatment, for the +0.037 mm ore sample, under the condition of grinding fineness -0.037 mm content of 15%, by using floatation flowsheet “one roughing-two scavenging-three cleaning”, the gold concentrate with the grade of 21.25 g/t, and the operation recovery 72.27%. The Result shows that the cyanide tailings can be comprehensively recovered.
