The efficient extraction of manganese from pyrolusite ore holds significant importance in meeting the global demand for this essential metal. This study focuses on optimizing the hydrometallurgical process for manganese recovery, utilizing nitric acid and distilled water as solvents. The investigation delves into the effects of varying nitric acid concentrations, reaction temperatures, agitation rates, and reaction times on the extraction efficiency of manganese, while simultaneously minimizing impurity co-dissolution. Through systematic experimentation, a comprehensive understanding of the interplay between process parameters and their impact on manganese extraction and impurity contamination is achieved. The research not only contributes to enhancing the fundamental knowledge of manganese extraction mechanisms but also aims to provide practical insights for industrial applications. Recommendations are made for advanced parameter optimization using modelling techniques, improved impurity control strategies, and exploration of environmentally sustainable alternatives. Additionally, the study emphasizes the importance of scaling up the optimized conditions to pilot-scale operations and conducting thorough economic analyses to evaluate the feasibility and cost-effectiveness of the proposed hydrometallurgical approach.

Keywords : Manganese, Pyrolusite Ore, Hydrometallurgical, Nitric Acid and Distilled Water.
