摘 要: 综述了国内外红土镍矿的处理现状。指出红土镍矿的开发要综合考虑矿石镍、钴含量和矿石类型的差异，以及当地燃料、水、电和化学试剂等的供应状况。现阶段回转窑干燥预还原−电炉还原熔炼工艺在红土镍矿的开发中仍占主导地位，加压酸浸法随着大型压力釜制造技术的成熟也越来越受到重视和应用。我国在红土镍矿的工程化方面很欠缺，元江贫红土镍矿的开发必须综合考虑镁的产品结构和经济利用，元石山镍矿的开发必须考虑铁的综合利用。

Abstract:The worldwide processing status of nickel laterite ores is reviewed. The overall exploration of laterite nickel needs to consider the contents of nickel and cobalt in ores, ore types, and the supplies of fuel, water, electricity, chemical reagents in local area. Currently, the process of drying and pre-reducing by rotary kiln-electric furnace reducing smelting is still dominating for the exploration of nickel laterite. Meanwhile, pressure acid leaching attracts much attention for practical application with the development of fabrication technology of large-scale pressure reaction kettle. The engineering integration in laterite nickel ores is still inadequate in China, for instance, the product distribution and economic utilization of magnesium must be systematically considered during the exploration of deficient laterite nickel in Yuanjiang area, and the overall utilization of ferrous should be evaluated as well for the exploration of Yuanshi Mountain ores.
Key words: nickel laterites; pressure leaching; nickel
