Environmental Impacts of Nickel Mining and Processing ...
Nickel deposits are typically found in low-grade ores (~1-2% nickel) thus making it highly energy intensive to extract and refine the metal. This leads to high emissions of greenhouse gases into the atmosphere and the use of large amounts of energy derived predominantly from fossil fuels ( 2 ).

2010-10-1 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).
