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.
