This study investigated the optimum conditions for the leaching of manganese-rich iron ore for subsequent beneficiation studies on a laboratory scale. The experiments were carried out by varying the concentration of H2SO4 solution and the leaching temperature. The properties of the iron ore were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), as well as photo-micrographic examination. The leaching experiments demonstrated that ore leaching increased with rising acid concentration and temperature. About 78.9% of the iron ore reacted within 120 minutes using a 4M H2SO4 solution at a temperature of 80°C. The activation energy (Ea) and the order of reaction were determined to be 31.14 kJ/mol and 0.979, respectively. The leaching data were fitted to the shrinking core model, indicating that the experimental results followed a diffusion-controlled mechanism. The residual product at optimal leaching was appropriately characterized and was found to contain silicate compounds.
