俄罗斯诺里尔斯克铜镍选矿厂过去堆存的浮选尾矿含有铂族金属 ,物质组成研究表明 ,铂族金属主要含在磁铁矿中。采用离心选矿机重选 -浮选联合流程可获得铂族金属粗精矿 ,该产品进一步再磨和摇床选别 ,精矿含 5 -7kg/t铂族金属 ,该产品可送冶炼处理。该工艺可综合利用尾矿中的有用金属。
In the past, the flotation tailings deposited at the Norilsk copper-nickel concentrator in Russia contained platinum group metals. Studies on the composition of the materials indicate that the platinum group metals are mainly contained in magnetite. Centrifugal concentrator re-election - flotation joint process can be obtained platinum group crude ore concentrate, the product further regrind and shaker election, the concentrate containing 5 -7kg / t PGM, the product can be sent to the smelting treatment. The process can be integrated utilization of the tailings of the useful metals.
