摘要：

硫化矿、红土镍矿和海底含镍锰结核是世界上主要的三类镍资源,但海底含镍锰结核难以开采利用，硫化矿资源也日益枯竭，从红土镍矿中提取镍已成为目前重要的研究方向。本文结合近年来红土镍矿处理工艺的研究成果，着重阐述了火法处理工艺（小高炉冶炼工艺和RKEF工艺等）、湿法处理工艺（常压酸浸、加压酸浸等）、火法湿法联合工艺（还原焙烧-磁选等）的研究新进展，并展望了红土镍矿未来的发展方向。

Abstract:

Sulphide ore,laterite nickel ore and nickel-manganese nodules on the seabed are three main types of nickel resources in the world.However,nickel-manganese nodules on the seabed are difficult to exploit and the sulphide ore resources are also depleted.The extraction of nickel from laterite nickel ore has become an important research direction.Combined with the research results of the treatment processes of lateritic nickel ore in recent years,the pyrometallurgy (small blast furnace smelting process and RKEF process,etc.),hydrometallurgy (normal pressure acid leaching,pressure acid leaching,etc.),combined hydro-pyrometallurgical process (reduction roasting-magnetic separation,etc.) are emphatically introduced in this paper,and their development trends are also prospected.

Key words: Laterite nickel ore, Treatment processes, Development direction
