WebWhen limonite ores were reduced, the mineral phases formed were magnetite, taenite and fayalite. Taenite is an iron-nickel alloy mineral containing 20% to 65% nickel. X-Ray Diffraction (XRD) patterns showed that taenite becomes more dominant as the temperature increased from 650 to 750 C, but upon further heating, the taenite disappeared. Lateritic nickel ores formed by intensive tropical weathering of olivine-rich ultramafic rocks such as dunite, peridotite and komatiite and their serpentinized derivatives, serpentinite which consist largely of the magnesium silicate serpentine and contains approx. 0.3% nickel. This initial nickel content is strongly enriched in the course of lateritization. Two kinds of lateritic nickel ore have to be distinguished: limonite types and silicate types.
