Economic nickel resources are found in sulfide and laterite ores. Nickel is mainly produced from sulfide ores (about 60%) although in terms of known resources about 60% is found in laterites while 40% is contained in sulphides. This is due to the more complex processing required for laterites (Mudd 2010).
