Electrolytic manganese metal (EMM) produced from recyclable resources has recently gained increasing attention due to the scarcity of high-quality natural and its broad range applications. This review summarised recent progress in recovery techniques, including pyrometallurgy hydrometallurgy. It also critically assessed processes mechanisms involved electrodeposition for Mn chloride- sulphate-based systems, with a major focus on electrode reactions nucleation growth. The key optimisation factors influencing electrodeposition, such as electrolytes, power consumption, additives, cell structures, materials, were analysed, particular their impact current efficiency, specific energy product quality. research directions highlighted address practical challenges enhance sustainability EMM process, which mainly includes improving ecological outcomes reducing both operating investment costs. Promising strategies simultaneous production electrolytic dioxide (EMD) identified, comprised applying membrane technology, ionic liquids, recycling reusing waste exploring hybrid techniques. results this study showed that prospective approaches are driven by need reduce costs, improve quality through sustainable technological advancements. can be used comprehensive guide scientific communities.

China is the world’s leading producer of molybdenum–copper concentrates, an industry noted for its high energy demand and considerable environmental burdens. This study applies a cradle-to-gate life cycle assessment to production concentrate in Lesser Khingan Mountains, utilizing ReCiPe 2016 midpoint method coupled with Monte Carlo uncertainty analysis. The results indicate that human carcinogenic toxicity represents greatest risk, followed by marine freshwater ecotoxicity. Contribution analysis reveals grinding stage dominant impact driver—particularly due hexavalent chromium emissions—affecting climate change potential, fossil resource depletion. Scenario testing demonstrates upgrading technology, enhancing electricity efficiency, substituting conventional renewable sources can markedly mitigate these impacts. However, because implementation barriers, such as capital costs, retrofit downtime, uncertainties supply chain, pilot phase necessary before deployment at full scale. Quantitatively, one tonne corresponds 0.05 DALYs health damage, 1.11 × 10−4 species.year ecological loss, USD 3488.82 These provide constructive references sustainable development mining contribute achieving China’s dual carbon targets through transformation low-carbon technological innovation.
