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.

1989-7-1  The recently discovered lateritic nickel ore deposit on the summit area of the Tagaung Taung contains about 40 million DMT nickel-saprolite ore with approximately 2% Ni. The serpentinite massif is covered with a thick weathering mantle consisting of saprolite, limonite, and an allochthonous lateritic surface layer. The thickness, nickel content, and physical properties of the ore are very ...

Many nickel deposits are known in Brazil, accounting for about 350 10 6 tons of ore with an average of 1.5% Ni. All are of the lateritic type. These deposits are scattered throughout the country, being rarer in the Northeastern Region and in the South, below 25 °S latitude. They are mainly associated with mafic-ultramafic massifs of large dimensions and ultramafic alkaline complexes, and ...

In Brazil, the same processes responsibleforthe formation of the thick lateritic mantle, which covers nearly 65 % of its territory, are also responsible for metal accumulation which forms, under special condition, the lateritic ore deposits. In the origin ofthose accumulation. the parent rock composition and/or the convergence of the biological and morphoclimatic factors play a fundamental role.
