The extraction of nickel increases with increasing H 2 SO 4 concentration from 0.6 M to 1.2 M, above which it hardly changes as the concentration further increases. Therefore, the optimum concentration of sulfuric acid was considered as 1.2 M, and further experiments were performed with this concentration.
