Abstract :
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.
