【摘要】：内蒙古某高炭含铜铅精矿-38μm占94.5%,铅、铜含量分别为52.73%和1.63%,主要铅矿物为方铅矿,含量达60.24%,主要铜矿物为黄铜矿,含量达4.33%,黄铜矿单体解离度达90%,具备很好的铜铅分离条件。实现铜铅高效分离既有利于提高铅精矿品质,又有利于优化产品方案,提高产品的附加值,因此,采用实验室合成的可溶性好、无毒、易降解有机药剂ZJ-88为抑铅浮铜抑制剂,进行了铜铅分离试验。结果表明,试样经1粗3扫开路浮选流程先浮出可浮性好的有机炭质物和活性极高的微细粒铅矿物,再采用1粗2精2扫抑铅浮铜闭路流程分离铜铅,最终获得了铜品位为21.83%、铜回收率为44.59%的铜精矿,以及铅品位为54.24%、铅回收率为99.45%的铅精矿。新型高效有机抑制剂ZJ-88的使用对从高炭含铜铅精矿中成功分离出合格铜精矿,且使铅精矿铅品位提高1.51个百分点起着决定性的作用。
[Abstract]:The content of lead and copper is 52.73% and 1.63, respectively. The main lead mineral is galena, which contains 60.24%, and the main copper is chalcopyrite, the main copper ore is chalcopyrite, and the main copper mineral is chalcopyrite, and the main lead mineral is galena with a content of 60.24 渭 m, and the main copper content is chalcopyrite. The content of chalcopyrite is 4.33, the degree of dissociation of chalcopyrite monomer is 90, and the conditions for separation of copper and lead are very good. The realization of high efficiency separation of copper and lead is not only conducive to improving the quality of lead concentrate, but also to optimizing the product plan and increasing the added value of the product. The separation test of copper and lead was carried out by using the soluble, nontoxic and easily degradable organic agent ZJ-88 as the inhibitor of copper floatation in the laboratory. The organic carbon with good floatability and microfine lead mineral with high activity were first floated by the 1 coarse 3 sweep open circuit flotation process, and then copper lead was separated by the closed circuit process of 1 coarse 2 fine 2 scavenging and 2 scavenging floating copper. Finally, a copper concentrate with a copper grade of 21.83 and a copper recovery rate of 44.59%, and a lead concentrate with a lead grade of 54.24 and a lead recovery of 99.45% were obtained. The use of a new high efficiency organic inhibitor, ZJ-88, has successfully separated qualified copper concentrate from high carbon copper bearing lead concentrate. It also plays a decisive role in raising lead grade by 1.51%.
