Optimization of Fe2O3 compositions for nickel leaching from laterite ores is required to obtain the optimum nickel grade in the leaching product. The effect of Fe2O3 on the hydrometallurgical process of nickel laterite has been reported clearly in this work. The optimization of Fe2O3 composition was obtained by mixing two different types of nickel laterites, i.e., saprolite and limonite, in which the various weight ratios were 2:3; 1:4; 1:1; 4:1; and 3:2. The mixed nickel laterites were heated at 300 °C. Then, the samples were leached using sulfuric acid (1.5M) at the temperature of 110 °C for 1 hour. The XRD analysis was performed on the mixed, heated ores to investigate the phase transformation. The leaching products were analyzed by ICP-OES for analyzing the nickel grade. The optimum condition was the weight ratio (saprolite/limonite) of 1:4 and heating temperature of 300 °C, which resulted in a nickel percentage of 2.18 wt%.
