IntroductionPropertiesHistoryFormationResourcesMiningProcessingFurther InformationAfter mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and chemical processing methods. The concentrates are then smelted in a furnace to produce a sulfide ‘matte’ with up to 70% Ni. The final stage of processing is refining, involving pyrometallurical heating and hydrometallurgical chemical pr…
