Nickel Processing

Laterite and sulphide nickel deposits require different processing routes.

Laterite HPAL

High-pressure acid leaching at 250-270°C dissolves nickel and cobalt. Solvent extraction and electrowinning produce nickel cathode.

Sulphide Flotation

Nickel sulphide ores (pentlandite) are processed by flotation to produce concentrate for matte smelting.
