Two broad ore types. Nickel occurs in two broad ore types: laterite (oxide) ores, principally located in tropical and sub-tropical areas, and; sulfide ores, principally located in the temperate to sub-Arctic regions. Major nickel mining locations are depicted in the map – but some of these locations have many operations, and some only one.

4. Copper- Nickel Ore Flotation Process When process copper-sulfide nickel ore, collector and frothier will be used in order to better results. A basic principle of copper-sulfide nickel ore process is that it is better to let copper assimilate into nickel ore rather than the opposite. For it is easier to recovery cooper from nickel concentrate.
