This is shown in Fig. 5 (a) from a thermodynamic perspective, but this process is rarely used in industrial production due to the low nickel recovery. Two key issues for low recovery of nickel by the above process is that metallic nickel disperses in the ore and unreduced Ni 2+ are incorporated into the fayalite structure as substitutes ...Web
