    2019-9-1  This is supplied from both sulfide and laterite ores, but currently laterites are becoming more attractive for nickel production due to the depletion of high grade nickel sulfide ores. Laterites are generally processed through hydro or pyro-metallurgy and therefore, pre-concentration of nickel before such processes is very important.
