【摘要】：內(nèi)蒙古某高炭含銅鉛精礦-38μm占94.5%,鉛、銅含量分別為52.73%和1.63%,主要鉛礦物為方鉛礦,含量達(dá)60.24%,主要銅礦物為黃銅礦,含量達(dá)4.33%,黃銅礦單體解離度達(dá)90%,具備很好的銅鉛分離條件。實(shí)現(xiàn)銅鉛高效分離既有利于提高鉛精礦品質(zhì),又有利于優(yōu)化產(chǎn)品方案,提高產(chǎn)品的附加值,因此,采用實(shí)驗(yàn)室合成的可溶性好、無毒、易降解有機(jī)藥劑ZJ-88為抑鉛浮銅抑制劑,進(jìn)行了銅鉛分離試驗(yàn)。結(jié)果表明,試樣經(jīng)1粗3掃開路浮選流程先浮出可浮性好的有機(jī)炭質(zhì)物和活性極高的微細(xì)粒鉛礦物,再采用1粗2精2掃抑鉛浮銅閉路流程分離銅鉛,最終獲得了銅品位為21.83%、銅回收率為44.59%的銅精礦,以及鉛品位為54.24%、鉛回收率為99.45%的鉛精礦。新型高效有機(jī)抑制劑ZJ-88的使用對(duì)從高炭含銅鉛精礦中成功分離出合格銅精礦,且使鉛精礦鉛品位提高1.51個(gè)百分點(diǎn)起著決定性的作用。
[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%.
