Whether high-grade or low-grade, nickel ores need to be processed after mining, in order to upgrade their nickel content from 1-4% Ni to 10-20%. Concentrating the nickel ores usually takes place close to the mine site, and involves chemical and physical processes to crush the ore and separate the nickel-bearing and gangue minerals.

Nickel is commonly present in two principal ore types – sulfide or laterite ores. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt, and sometimes other precious metals such as gold or platinum and palladium (generally grouped as platinum group metals or PGMs). Laterite ores are formed near the surface following extensive ...
