Reviews on Processing & Extraction Technology of Laterite-nickel Ore

The present situations of nickel resources and extraction production were briefly introduced in this pa- per. The main processes and developments of processing laterite-nickel ore at home and abroad were demonstrated through microbial leaching, microwave pretreating as well as pyrometallurgy for ferronickel and nismatte, hy- drometallurgy for reduction roasting ammonia leaching, high-pressured acid leaching, etc. Challenges and industrial prospects for bioleaching are discussed. The researches revealed that hydrometallurgy united pretreating have tak- en obvious advantages and are key to the successful application on commercially, and microbial leaching methods will have very good prospects for developments in the future.
