Lateritic Nickel Ore Deposits

The Lateritic Nickel-Ore Deposits | SpringerLink

Abstract. Nickel belongs to the transition metal family and shows close chemical similarities with Fe and Co. Even more than these elements, it is concentrated in silicated Fe-Mg minerals by octahedral substitution with Fe 2+ ions. Thus, the mean mineral/ matrix partition coefficient of Ni is 14.0,5.0 and 2.6 for basaltic whole rocks, for olivine, and orthopyroxene and clinopyroxene, respectively.

Ore Deposits. Typical nickel laterite ore deposits are very large tonnage, low-grade deposits located close to the surface.
