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,
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%.
