The processing status of nickel laterite ores around the world is reviewed in this paper.Currently, the reduction smelting process that dries and pre-reduces the ore in a rotary kiln-electric furnace is still predominantly operated for the exploration of nickel laterite.Meanwhile, pressure acid leaching is attracting more attention for practical application with the development of fabrication technology of large-scale pressure reaction autoclave.During the exploration of laterite ores with low nickel content, such as limonite ore and gamierite/saprolite ore, the comprehensive utilization of iron and magnesium from the ores must also be considered.
