Ore Genesis. Nickeliferous laterite is formed by weathering and oxidation of ultramafic rocks which preferentially enriches the laterite (a residual regolith material) in nickel at the expense of magnesium and silica which are removed by dissolution in the environment.. Lateritization of ultramafic igneous rocks (serpentinite, dunite, or peridotite containing about 02 - 0.3% nickel) …

More nickel laterite ores are imported into China because of the depletion of domestic nickel sulfide resources. Consequently, it is of great importance to the Chinese economy to effectively utilize low grade nickel laterite ore [7]. Nickel laterite ores are formed by the weathering of olivine bedrock in tropical to sub-tropical climates [8,9].
