-
摘要:
本文研究了某铜镍多金属硫化矿的工艺矿物学，结果表明该矿石原矿中主要有用矿物为镍黄铁矿和黄铜矿，主要金属硫化物为磁黄铁矿，少量黄铁矿。脉石矿物主要为蛇纹石、橄榄石和阳起石等镁硅酸盐矿物。矿石具有较高的综合回收利用价值，建议开展对该矿铂、钯、金、银的赋存状态研究和相应的选矿工艺研究，以最大限度地回收该矿中贵金属矿物。
Abstract:In this study, the process mineralogy of a copper-nickel polymetallic sulfide ore was studied. Results show that the main useful minerals in the ore are nickel-pyrite and chalcopyrite. The main metal sulfides are pyrrhotite and a small amount of pyrite. The gangue minerals are mainly magnesium silicate minerals such as serpentine, olivine and actinolite. The ore has a high comprehensive recycling value. It is recommended to carry out research on the occurrence state of platinum, palladium, gold and silver and the corresponding beneficiation process to maximize the recovery of precious metal minerals in the ore.
