多金属含金矿石综合回收试验研究

对内蒙古某矿多金属含金矿石进行了综合回收试验研究。根据矿石性质,通过流程对比试验,采用原矿重选—重尾混合浮选—混合精矿氰化—氰渣浮选工艺流程,可实现就地产金、银,获得合格的铜精矿、铅精矿、锌精矿,金、银、铜、铅、锌、硫回收率分别为88.81%、93.38%、75.23%、55.36%、65.12%、83.83%。

Test and study on comprehensive recovery from a polymetailic gold bearing ore

Tests on comprehensive recovery from a polymetallic gold bearing ore in Inner Mongolia were conducted. Based on properties of the ore and through process comparative trial, a flowsheet of gravity separation of run-of- mine ore, bulk flotation of the gravity residue, cyanidation of the mixed concentrate, and flotation residue, was used to achieve local production of gold and silver with qualified copper concentrate, of the cyanidation lead concentrate,and zinc concentrate, and the recoveries for Au, Ag, Cu, Pb, Zn, and S being 88.81%, 93.38 %, 75.23 %, 55.36 %, 65.12 %, 83.83 % respectively.
