Abstract:The general situation of distribution, exploitation and utilization of nickel resources was introduced. The basic process, advantages and disadvantages and application prospect of some hydrometallurgy processes, such as ammonia leaching, high pressure acid leaching, atmospheric-pressure acid leaching and heap leaching, were elaborated. The research and application of bio-hydrometallurgy for nickel oxides and sulfides were summarized. It is suggested that the key to solve the problem of high magnesium is bioleaching at elevated pH. Finally, the development direction of processes for high-magnesium nickel ore was prospected. The atmospheric-pressure acid leaching and bio- hydrometallurgy are the hot areas of research.

 

Key words: high-magnesium nickel ore; nickel sulfides; nickel oxides; hydrometallurgy; bioleaching;
