    Most mined nickel derives from two types of ore deposits that form in very different geological environments: magmatic sulfide deposits, where the principal ore mineral is pentlandite [ Ni,Fe 9 S 8 ], and laterites, where the principal ore minerals are nickeliferous limonite [ Fe,NiO OH] and garnierite a hydrous nickel silicate.
