01.09.2019For 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.
