针对某低品位硫化铜矿进行工艺矿物学研究,结果表明,该铜矿石矿物成分复杂,主要原生硫化铜矿物为黄铜矿,次生硫化铜矿物为铜蓝和少量辉铜矿、砷黝铜矿,氧化铜矿物为黑铜矿;脉石矿物以石英、绿帘石、石榴石、透辉石、透闪石、绿泥石、绢云母、长石为主。原矿含铜0.55%,铜在原生硫化铜和次生硫化铜矿物中的分布率分别为42.18%和36.36%。黄铜矿为细~微细粒不均匀嵌布,粒度集中在0.01~0.16 mm;铜蓝嵌布粒度则集中在0.02~0.16 mm。由于部分硫化铜矿物常和石英、磁黄铁矿共生,选择合理的磨矿细度,使细粒嵌布的铜矿物充分单体解离是本矿石获得较好选矿指标的关键。
針對某低品位硫化銅礦進行工藝礦物學研究,結果錶明,該銅礦石礦物成分複雜,主要原生硫化銅礦物為黃銅礦,次生硫化銅礦物為銅藍和少量輝銅礦、砷黝銅礦,氧化銅礦物為黑銅礦;脈石礦物以石英、綠簾石、石榴石、透輝石、透閃石、綠泥石、絹雲母、長石為主。原礦含銅0.55%,銅在原生硫化銅和次生硫化銅礦物中的分佈率分彆為42.18%和36.36%。黃銅礦為細~微細粒不均勻嵌佈,粒度集中在0.01~0.16 mm;銅藍嵌佈粒度則集中在0.02~0.16 mm。由于部分硫化銅礦物常和石英、磁黃鐵礦共生,選擇閤理的磨礦細度,使細粒嵌佈的銅礦物充分單體解離是本礦石穫得較好選礦指標的關鍵。

The process mineralogy of a low grade sulfide copper ore was researched in this paper. The results show that mineral compositions of the copper ore are complex and chalcopyrite is primary sulfide copper mineral, while the secondary sulfide copper minerals are covellite and a spot of chalco-cite and tennantite,and tenorite is the main oxidized copper mineral .The main gangue minerals are quartz, epidote, garnet, diopside, tremolite, chlorite, sericite and feldspar.The grade of copper in raw ore is 0.55%and the distributions of Cu in primary and secondary sulfide copper are 42.18%and 36.36%respectively.Chalcopyrite is finely-microfinely uneven disseminated between 0.01 mm and 0 .16 mm, while chalcocite is between 0.02 mm and 0.16 mm.As the copper minerals partly in-tergrow with quartz and pyrrhotine, choosing a reasonable grinding fineness to ensure full liberation of the fine-disseminated copper minerals is the key to obtain a good beneficiation indexes.
