摘要: 河南金渠黄金股份有限公司金渠金矿已闭库的马桥沟尾矿库存有尾矿180万t左右,平均金品位达0.87 g/t。为开发利用该尾矿,对其进行了浮选试验研究。试验结果表明,在-200目占78%的再磨细度下,采用丁基黄药+丁铵黑药作为联合捕收剂,辅之以硫酸铜的活化作用,经一粗二精二扫闭路浮选,可从该尾矿中获得金品位为12.49 g/t,金回收率为81.36%的金精矿。

Abstract: The closed Maqiaogou tailing reservoir in Jinqu Gold Mine of Henan Jinqu Gold Co., Ltd.owns about 1.8 Mt tailing resources at an average gold grade of 0.87%.To make use of the tailings, a flotation experiment is carried out.The results showed that a gold concentrate grading 12.49 g/t at an 81.36% recovery was obtained from tailings by a closed-circuit of one stage rough concentration, two stage cleaning and two stage scavenger with butyl xanthate and butyl aerofloat as collector and copper sulfate as activator under regrinding of 78% -200 mesh.
