摘　　要：对内蒙古某矿含锌金银矿石进行了选矿试验。根据矿石性质,采用原矿氰化—浸渣浮锌流程,可实现就地产金、银,浸出率分别为78.89%、63.77%,浸渣浮锌,锌的回收率为84.64%,锌精矿品位43.25%;采用原矿混合浮选—精矿氰化—浸渣浮锌流程,同样可实现就地产金、银,浸出率分别为81.14%、56.44%,精矿浸渣浮锌,锌的回收率为74.55%,锌精矿品位为50.17%。Experimental studies on zinc-containing gold silver ore dressing are carried out in Inner Mongolia. Aiming at the ore properties, with ore cyaniding -leaching slag floatation for zinc flowsheet, gold and silver could be product on site. And the recovery rate of gold, silver and zinc is respectively 78.89%, 63.77% and 84.64%, the grade of zinc concentrate is 43.25%. With ore bulk flotation - concentrate cyaniding - leaching slag floatation for zinc flowsheet, gold and silver could be product on site as well. And the recovery rate of gold, silver and zinc is respectively 81.14%, 56.44% and 74.55%, the grade of zinc concentrate is 50.17%.
