摘　　要：自20世纪80年代中期以来,镍的使用范围广泛,不锈钢一直是镍消耗的主要推动力。随着硫化矿资源的日趋枯竭,红土镍矿将是未来镍的主要来源。根据红土镍矿矿床不同的分层,介绍了不同的处理工艺,归纳起来大致有以下几种,即火法工艺、湿法工艺、氯化离析-磁选、还原硫化焙烧-磁选以及生物浸出等,为红土镍矿在我国的合理利用提供参考。Nickel has been widely used since the middle 1980s, with stainless steel as the main product of its consumption. With the sulfide nickel ore becoming deficient day by day as a resource, the development of the lateritenickel ore will be the main source of nickel industry in the future. In this paper, to provide the reference for the reasonable utilization of the nickel-bearing laterite, hydrometallurgy, pyrometallurgy, chloridizing-magnetic separation, sulfide reducing roasting-magnetic separation and microbial leaching are introduced as the main ways of treating nickelbearing laterite, which according to the different layers of the laterite deposit.
