Nickel deposits can be classified into two main groups: laterites and sulphides. Even though nearly 70% of nickel resources are contained in laterites, the bulk of production comes from sulphides due to the complex and high-cost processing required for laterite. The sulphide ores are universally treated by flotation, and the...

As such, laterite-derived nickel will increase significantly in the near future. In general, production of nickel from sulfide ores involves either open cut or underground mining, followed by concentration via flotation, smelting of concentrates to produce a nickel matte, finally leading to refining of matte to produce a pure metal.
