(Read 1937), but have more commonly been exploited as sources of nickel (Ni) and aluminium (Al). The iron3 content of laterites can be lower than 1wt.% (weight percent, or proportion by molecular mass) but typically contains 15wt.% to 30wt.% (Aleva 1994:6; Kasthurba et al. 2007:Table 3), as well as a host of other contaminants.
Genesis and types of nickel laterites. 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.
Nickel can be produced from laterite ores by reduction−smelting process [1] or from sulfide ores by roasting−smelting process [2], and both of these processes generate slags, which will not only take up a lot of land, bring pollution to the environment, but will also cause waste of resources [3]. Similar to other
