The nickel ore sample particle size was reduced to −250 μm using a laboratory jaw crusher and rod mill. XRD analysis using the Rietveld method indicated that the sample was a magnesium silicate, with only 4.33% nickel-bearing mineral, lizardite [Mg 3 (Si 2 O 5 (OH) 4]. XRF analysis showed that nickel content in the ore was below 0.1%.Web

two types of ore, i.e. limonitic and saprolitic nickel laterite ore. Limonitic nickel ore has low content of Ni. The nickel content of limonitic nickel ore is 1.1 until 1.8wt%. On the other hand, the saprolitic nickel ore has higher nickel content than limonitic nickel ore. The nickel content in saprolitic nickel ore is about 2% or higher.Web

Gold occurs as discrete grains, usually from 1 to 10 µm in diameter, with a fineness of >990 ( et al., 1990). The remaining 70% of the gold in the regolith is hosted within the saprolitic clay and saprock zones. In contrast to the laterite zone, gold in the saprolite clays is relatively inhomogenous and has poorer continuity.Web

The lateritic ore is comprised of a dispersion halo in ferruginous pisoliths and retains its 'mushroom' distribution, even where buried. In ore-grade laterite deposits, gold mineralization is much larger (several kilometres long) in pisoliths than in saprolite and is thought to have formed by residual concentration by chemical wasting.Web
