摘要: 针对内蒙古某高银锡铜锌共生矿(Sn 0. 86%、Ag 125. 5 g/ t、Cu 0. 32%、Zn 1. 14%)现场分选工艺存在银、
铜回收率偏低的问题,开展了选矿工艺技术优化试验。在原矿粗磨(-0. 074 mm 占55%)保锡的前提下,提出“银铜快
浮—硫化矿混浮—银铜与锌硫分离—锌硫分离”新工艺,实现了银、铜、锌的高效回收。闭路试验获得综合银铜精矿
Cu 品位9. 62%、Ag 品位4 104. 99 g/ t,Cu 回收率82. 94%、Ag 回收率90. 29%;锌精矿Zn 品位42. 85%、Ag 品位316. 80
g/ t,Zn 回收率69. 94%、Ag 回收率4. 70%。研究结果表明,该工艺在保证锡回收的同时,显著提高了银铜回收率,为该
资源的综合利用提供了技术依据。

Abstract: Aiming at the problem of low recovery rate of silver and copper in the on-site separation process of a high silver-
tin-copper-zinc associated ore in Inner Mongolia (with Sn grade of 0. 86%,Ag grade of 125. 5 g/ t,Cu grade of 0. 32%,Zn
grade of 1. 14%),mineral processing technology optimization tests were carried out. On the premise of rough grinding of raw
ore (with the fraction of -0. 074 mm accounting for 55%) while ensuring tin preservation,a new process of "silver-copper rapid
flotation,sulfide ore bulk flotation,separation of silver-copper from zinc-sulfur,zinc-sulfur separation" was proposed,which
realized the efficient recovery of Ag,Cu and Zn. The closed-circuit test yielded a comprehensive Ag-Cu concentrate with Cu
grade of 9. 62%,Ag grade of 4 104. 99 g/ t,Cu recovery rate of 82. 94%,and Ag recovery rate of 90. 29%. Meanwhile,the zinc
concentrate achieved Zn grade of 42. 85%,Ag grade of 316. 80 g/ t,Zn recovery rate of 69. 94%,and Ag recovery rate of
4. 70%. The research results indicated that this process not only ensures Sn recovery,but also significantly improves the recovery
rates of Ag and Cu,providing a technical basis for the comprehensive utilization of this mineral resource.
