Abstract:The worldwide processing status of nickel laterite ores is reviewed. The overall exploration of laterite nickel needs to consider the contents of nickel and cobalt in ores, ore types, and the supplies of fuel, water, electricity, chemical reagents in local area. Currently, the process of drying and pre-reducing by rotary kiln-electric furnace reducing smelting is still dominating for the exploration of nickel laterite. Meanwhile, pressure acid leaching attracts much attention for practical application with the development of fabrication technology of large-scale pressure reaction kettle. The engineering integration in laterite nickel ores is still inadequate in China, for instance, the product distribution and economic utilization of magnesium must be systematically considered during the exploration of deficient laterite nickel in Yuanjiang area, and the overall utilization of ferrous should be evaluated as well for the exploration of Yuanshi Mountain ores.
Key words: nickel laterites; pressure leaching; nickel
