世界红土镍矿资源开发及湿法冶金技术的进展

随着硫化镍矿资源日趋枯竭，高效开发占全球镍资源72％的红土镍矿日益迫切。文章介绍了世界红土镍矿资源特点、国内外的开发现状，并阐述了其传统湿法生产工艺及进展。认为常压浸出和细菌浸出等新湿法流程具有工艺简单、能耗低、操作易于控制、投资少等优点，将会有很好的发展前景。

Development of Exploitation and Hydrometallurgical Processes of Nickel Laterite Resources in the World

As the nickel sulfide ore has beening exhausted,the efficient exploitation of nickel laterite ore,accounting for 72 percent of global nickel resources,becomes very urgent.The characteristics and exploitation status of nickel laterite resources are simply introduced in this article,and the traditional hydrometallurgical processes and development are also described.It is believed that the atmospheric leaching,heap leaching and Bioleaching etc,have the merits of simple process,low energy consumption,easy opera...
