摘要: 某金矿矿石中矿物种类丰富,有用成分较多,但矿山原选矿工艺只生产金精矿1种产品,影响企业效益。为此,分别采用铅金混合浮选—铅金分离—混浮尾矿选硫和铅金混合浮选—铅金分离两种选别流程对该矿石进行了选矿试验,结果表明,前者可以获得Pb品位为49.36%,Au含量为260.30 g/t的铅精矿,Au品位为34.20 g/t,Pb含量为2.21%的金精矿和S品位为42.31%的硫精矿,后者可以获得Pb品位为51.21%,Au含量为249.29 g/t的铅精矿和Au品位为24.26 g/t,Pb含量为1.05%的金精矿,

Abstract: There are various valuable components in a gold mine.The previous mineral processing technology can only produce one type of gold concentrate and make enterprises low efficiency.Hence,beneficiation tests on this ore were carried out by both separation flow-sheets consisting of lead-gold mixed flotation-lead-gold separation-sulfur separation from tailing mixed flotation and the lead-gold mixed flotation-lead-gold separation.The results showed that the former process can reach lead concentrate with Pb grade of 49.36% and Au content of 260.30 g/t,gold concentrate with Au grade of 34.20 g/t and Pb content of 2.21%,and sulfur concentrate with S of 42.31%; The latter can reach lead concentrate with Pb grade of 51.21% and Au content of 249.29 g/t and gold concentrate with Au grade of 24.26 g/t and Pb content of 1.05%.
