The possibilities of extracting valuable components and producing selective good-quality concentrates from hard-to-beneficiate crude ores are considered for the disseminated copper–nickel ores from the Norilsk district. The stated aim is achieved by a combined technology including beneficiation and hydrometallurgical processes. Beneficiation is aimed at producing a rich copper concentrate and a nickel–pyrrhotite product. The aim of the hydrometallurgical process is the leaching of a nickel–pyrrhotite product followed by the flotation production of a nickel concentrate. The flotation hydrometallurgical processing of a nickel–pyrrhotite product makes it possible to produce nickel concentrates of a higher quality than those synthesized using a traditional technology.

浮选联合湿法冶金技术用于弥散型铜镍矿的选矿和加工

从诺里尔斯克地区散布的铜-镍矿石中，考虑了从难选的粗矿石中提取有价值的成分和生产精选优质精矿的可能性。所述目的是通过包括选矿和湿法冶金工艺在内的组合技术来实现的。选矿的目的是生产丰富的铜精矿和镍-硫铁矿产品。湿法冶金工艺的目的是浸出镍-硫铁矿产品，然后浮选生产镍精矿。镍-硫铁矿产品的浮选湿法冶金处理使得生产比传统技术合成的镍精矿质量更高的镍精矿成为可能。
