摘　　要：镍矿是国民经济中一种重要的金属矿产资源,随着经济的发展,人们对镍矿资源的消耗呈逐年上升趋势。目前所查明的镍矿资源中,有近70%的镍矿资源都是硫化镍矿,近30%的镍矿资源属于红土镍矿。随着镍矿资源查明储量的下降,其镍矿资源的综合利用受到越来越多国家的重视。在查阅大量文献的基础上,简要的论述了镍矿资源的总体情况,概述了硫化镍矿常规的处理方法,以及近年来浮选法的一些实际应用及发展。最后,介绍了当前状况下红土镍矿的火法和湿法处理工艺现状及进展,以及一些其他处理镍矿石的方法。为以后镍矿石资源的综合利用和处理工艺的研究提供了一定的参考价值。Nickel ore is an important metallic mineral resource of national economy. Along with economic development, the consumption of nickel ore resources is increased year by year. Amongthe identified resources of the nickel ore, nearly 70% of nickel resources are nickel sulfide ore and nearly 30% are laterite. Since the reserve of the indentified nickel resource is declined,comprehensive utilization of nickel resource is given more and more attention by many countries. On the basis of reading large quantity of literature, this article discusses the general situation of nickel ore resources, then an overview of the conventional nickel sulfide ore processing-flotation, and some applica- tion and development of flotation methods in recent years ; Finally, this paper introduces the current situation and development of pyrometallurgy and hydrometallurgy process of laterite, and some other nickel ore processing methods, which provides a certain reference to the future comprehensive utilization and processing technology study of nickel ores.
