gravity separation of nickel laterite ore

Lateritic nickel ore deposits - Wikipedia

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.

Preconcentration strategies in the processing of nickel ...

Aug 01, 2015 · A number of physical separation techniques (screening, gravity and magnetic separation with and without roasting) have been investigated in the laboratory on three Western Australian low-grade Ni laterites. These tests confirm that the complex mineralogy of these three Ni laterite samples compromises any significant upgrading in Ni values.
