Selective Reduction of Laterite Nickel Ore

The lateritic nickel ore is an ore resulting from long weathering process, derived from ultra-basic rocks containing silicate and magnesium minerals. During this process, Mg and Fe in the silicate lattice are partially replaced by Ni in order to form mineral deposits with different nickel and impurity contents.
