Pre-concentration of nickel in laterite ores using

Sep 01, 2019 For example, in a nickel-cobalt laterite deposit in New South Wales, Australia, gravity separation followed by magnetic separation resulted in upgrading nickel from 0.9% to 1.1% at 57% recovery . Furthermore, Muir and Johnson (2006) demonstrated that in physical beneficiation using gravity, particle size is the key parameter.

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.

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.
