    • Ferruginous sulfide minerals containing non-ferrous metal values, such as nickel and cobalt are treated to concentrate the non-ferrous metal values in metallic iron. An intimate admixture of finely-divided non-ferrous-metal-bearing ferruginous sulfide minerals, iron oxide, and a suitable reducing agent is maintained at a temperature between about 800.degree. C. and 1000.degree. C. in an atmosphere non-oxidizing to iron to produce a metallic iron alloy containing the non-ferrous metal values from the sulfide minerals. The heated admixture is cooled and the concentrated non-ferrous metal values in the iron alloy are recovered by magnetic separation or hydrocloning.
    • 含有有色金属值的铁质硫化物矿物,例如镍和钴被处理以将有色金属的值集中在金属铁中。 细碎的含铁金属的铁质硫化矿物,氧化铁和合适的还原剂的紧密混合物在不氧化至铁的气氛中保持在约800℃至1000℃之间的温度 以生产含有来自硫化矿物质的有色金属值的金属铁合金。 将加热的混合物冷却,并通过磁力分离或氢克隆来回收铁合金中的浓缩的有色金属值。
