· Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) (Naldrett, 2002, Hoatson et al., 2006).
