摘要
针对新疆某嵌布粒度细、共生关系复杂、含金矿物分散的含金低品位铅锌矿石,通过铅、锌、硫依次优先浮选,得到三种精矿产品,铅精矿含铅46.08%、金73.64 g/t,锌精矿含锌50.95%、金14.32 g/t,硫精矿含硫35.06%、Au11.39 g/t,金的总回收率达到81.15%。
The low - grade - Pb - Zn gold ore is characteristics of fine mineral grain distribution, complex intergrowth correlation and dispersed gold mineral. In this study, three products including Pb concentrate, Zn concentrate and S concentrate are obtained by a selective flotation process in turn respectively. The Pb concentrate contains 46.08% Pb and 73.64 g/t Au, Zn concentrate contains 50.95% Zn and 14.32 g/t Au, S concentrate contains 35.06% S and 11.9 g/t Au, and the total recovery of gold is 81.15%.
