  • Nickel Laterite Ore Deposits: Weathered Serpentinites

    Nickel laterite ores account for over 60% of global nickel supply. They are the product of intensive deep weathering of serpentinites under humid tropical conditions. Nickel is concentrated to over 1.0 wt% and is hosted in a variety of secondary oxides, hydrous Mg silicates and smectites.

  • 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.

  • Lateritic nickel deposits of Brazil NASA/ADS

    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

  • Where are the world's top nickel deposits located?

    Russian nickel deposits are classified as nickel sulfide, which are the primary source of high-grade nickel ore. According to Ahead of the Herd, 58 percent of global nickel production comes from nickel sulfide. The largest sulfide deposit in the country is found in Norilsk, which also happens to be the largest across the globe.

  • Nickel Deposits of USGS

    nickel ore deposits are closely associated with mafic and ultramafic in­ trusive rocks, and the nickel in the ore bodies was probably derived either from the intrusives themselves or from similar rocks at depth. Thus the original source of most of the nickel ore bodies found in North America and elsewhere in the world was probably the mantle.
