由冶金部及甘肃冶金局主持的“采用脱泥—浮选—磁选—浮选联合流程从露天矿磨浮尾矿中回收镍铜的研究与工业实践”技术鉴定会,1981年12月6～9日在金川有色金属公司召开。金川最早开发的露天矿矿石系贫镍硫化矿石,由于矿石结构类型的不同以及矿体受到多次热液蚀变和氧化作用,致使其可选性极为复杂。多年来采用单—浮选流程的土产实践表明,在精矿镍
Technical Appraisal Conference, “Research and Industrial Practice on Recovery of Nickel-Copper from Floating Tailings from Opencast Mines by Silt-Flotation-Magnetic Separation-Flotation Process” hosted by Ministry of Metallurgy and Gansu Metallurgical Bureau, December 1981 ~ 9 Jinchuan Nonferrous Metals held. The first open-pit ores of Jinchuan were depleted in nickel-sulphide ores. Due to the different types of ores and the multiple hydrothermal alteration and oxidation of ore bodies, their selectivity is extremely complicated. Indigenous practices that have adopted single-flotation processes over many years show that in concentrate nickel
