中文摘要:本文针对青海省某铜镍钴多金属矿进行选矿实验研究, 该矿为原生硫化矿,原矿中的镍、铜、钴的含量分别为0.80%、0.20%、0.025%,铜矿物主要为黄铜矿,镍矿物主要为镍黄铁矿,钴以类质同象形式赋存在镍黄铁矿中,非金属矿物主要为透闪石、滑石、辉石。采用以铜为主的滑石-铜镍等可浮-尾矿强化回收镍工艺流程[1-6],闭路试验指标,铜精矿含铜25.15%,含镍1.23%,铜回收率62.14%;镍精矿含镍7.95%,含铜0.40%,含钴0.24%,镍回收率80.67%,钴回收率75.76%。

Mineral processing of nicke polymetallic ore of Qinghai
Abstract:Studied at the nickel polymetallic ore of Qinghai , it contains 0.80% nickel ,0.2% copper and 0.025%cobalt ,that is a typical primary sulfide ore. The main copper mineral is chalcopyrite, pentlandite is the dominant nickel mineral, cobalt exist in pentlandite as isomorphism . The main gangue mineral is tremolite, talc and pyroxene. Process of tacle –copper nickel iso-flotation and nickel flotation was adopted. According to the closed circuit tests, copper concentration contains 25.15%copper , 1.23% nickel at a 62.14% copper recover, meantime , nickel concentration contains 0.4%copper, 0.24%cobalt and,7.95% nickel at a 80.67% nickel recovery and 75.76%cobalt recovery.
