— Processing. After 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 …

— The sulfating roasting process of nickel sulfide ore is essentially a process of selective oxidation of metals in minerals. In this process, air or oxygen-enriched air is generally used as oxidant, and a multiphase reaction takes place between solid phase and gas phase. After roasting, valuable metals such as nickel, cobalt, and copper are ...
