摘　　要：当今世界工业发展快速,金属镍的消耗日益增加,高品位硫化镍矿日益减少,如何高效开发和利用红土镍矿逐渐成为研究的热点。分析了红土镍矿回转窑―电炉还原熔炼、还原焙烧―磁选、还原硫化熔炼3种火法工艺以及常压酸浸、高压酸浸及其他如氯化冶金和生物冶金等工艺研究现状,指出了未来红土镍矿资源开发利用及冶金工艺选择需注意的问题及未来发展方向。With the rapid development of industry in the world,the consumption of metal nickel is increasing day by day,and the high-grade nickel sulfide ore is decreasing day by day.How to efficiently develop and utilize laterite nickel ore has gradually become a research hotspot.This paper analyzed the three pyrometallurgical processes of laterite nickel ore(rotary kiln-electric furnace reduction smelting,reduction-roasting magnetic separation and reduction-sulfuration smelting)as well as the research status of atmospheric pressure acid leaching,high pressure acid leaching and other metallurgical processes such as chlorination metallurgy and bio metallurgy,and pointed out the problems in the development and utilization of laterite nickel ore resources and the selection of metallurgical processes,as well as the future development direction.
