Pentlandite
For instance, nickel is used in the ceramic components of some kinds of fuel cells. The fraction of nickel in pentlandite (nickel ore) is only 5.5 × 10 −3 g Ni/g ore. To supply 1 g of pure nickel to an industrial process requires that at least 181 g of pentlandite be dug. If the nickel mine is underground, the upper layers of topsoil and ...

A Robust Recovery of Ni From Laterite Ore Promoted by Sodium
Laterite ore is one of the important sources of nickel (Ni). However, it is difficult to liberate Ni from ore structure during reduction roasting. This paper provided an effective way for a robust recovery of Ni from laterite ore by H2 reduction using sodium thiosulfate (Na2S2O3) as a promoter. . It was found that a Ni content of 9.97% and a Ni recovery of 99.24% …

Pre-concentration of nickel in laterite ores using physical separation
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 (Aral, 2013). Furthermore, Muir and Johnson (2006) demonstrated that in physical beneficiation using gravity, particle size is the key parameter.

Definition and Process Optimization
Nickel laterites form under humid tropical conditions during the weathering of ser-pentinite rocks. The mineralogy and ore grade depend on the lithology and climate during the formation of the deposit. Nickel is hosted in several minerals such as oxides, Mg sili-cates and clays.
