摘要
国外某铜、铅、锌多金属硫化矿,矿石性质复杂,采用化学分析、MLA矿物自动检测系统及光学显微镜等测试手段,进行详细工艺矿物学研究。结果表明:该矿石中铜锌硫化物嵌布关系密切而复杂,闪锌矿中镶嵌微细粒黄铜矿,对铜锌分选产生不利影响。方铅矿主要充填在闪锌矿颗粒间,少部分方铅矿与黄铁矿、黄铜矿、脉石矿物构成连晶或包裹。矿石中含有大量的白云石、绿泥石,磨矿过程中易泥化,恶化浮选矿浆环境,对铜铅锌浮选分离造成不利影响。因此,选择磨矿细度应适宜。
The property of foreign copper-lead-zinc polymetallic sulfide ore is complex .The study process mineralogy on copper-lead-zinc polymetallic ore sample is investigated by chemical analysis, mineral liberation analyser(MLA) and microscopic observation. The results show that the inlay relation of copper and zinc sulfide in ore is close and complex with fine grained mosaic of chalcopyrite in sphalerite. This relation has adverse effect on the separation of copper and zinc. Galena fills mainly in sphalerite inter particles. A small part of galena composes crystal or package with pyrite chalcopyrite and gangue mineral. The ore contains a large amount of dolomite and chlorite, which mud easily in grinding process and deteriorate flotation pulp environment. It has a negative effect on the separation of copper and zinc. Therefore, the choice of grinding fineness should be appropriate.
