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.

Oct 17, 2019· The name "laterite" is a derivative of the latin word later, or "brick". A long time ago, bricks were carved out of laterites and used as building material in Asian countries such as India and Cambodia. The average grade and tonnage of nickel –cobalt bearing laterites is 1.3 % Ni and 0.04% Cobalt at 56 Million tonnes.

Despite the high grade, recovery of rare earths from laterite ores by conventional mineral beneficiation processes such as froth flotation, density or magnetic separation is difficult due to the ...

Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock. Tropical weathering is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils.
