摘　　要：随着镍资源的需求不断增加,镍含量较高且易开采的硫化镍矿日益枯竭,镍资源的开发利用逐渐转向红土镍矿。介绍了红土镍矿资源的特点和分布状况,并根据矿物的不同的结构特点分析其在工业上所应用的主要工艺流程。通过分析不同处理工艺的优缺点及其国内外的相关研究现状,发现湿法浸取红土镍矿工艺有着较好的应用前景。With the increasing demand for nickel resources, the development and utilization of nickel resources is gradually shifting to nickel laterite ore because the nickel sulfide ore which is high-grade and easily mined are deple- ted. The characteristics of nickel laterite resources are introduced and the main process applied in industry is analyzed according to the own structural characteristics of different minerals. By analyzing the advantages and disadvantages of the different treatment processes and the researches at home and abroad, the conclusion is that the hydrometallurgy process of nickel laterite is perferable application prospects.
