Abstract

Abstract:

Electrolytic manganese residue（EMR），enriched with heavy metals（Mn，Cr，Pb） and ammonia nitrogen（NH₃-N），has emerged as a critical challenge hindering the green development of the manganese metallurgical industry.The origins and physicochemical properties of EMR generated during electrolytic manganese production，along with its ecological hazards were presentsed.The recent advancements in decontamination and resource utilization technologies for EMR were systematically reviewed.To address pollution control requirements，cementation systems，high-temperature curing，and chemical stabilization technologies achieved heavy metal and ammonia-nitrogen immobilization through multi-mechanism synergies while enabling construction material utilization.However，long-term environmental risks and carbon emissions during treatment required further investigation.Regarding leaching processes，chemical leaching，bioleaching，and electric field-enhanced leaching technologies accomplished dual objectives of detoxification and resource recovery through selective extraction of valuable components.These approaches still faced challenges including high acid consumption，prolonged processing cycles，and residual toxicity in treated residues.Future research should prioritize synergistic treatment of multi-source solid wastes and short-loop recycling of leaching solutions to facilitate the transition of the electrolytic manganese industry toward a resource-environment-economy balanced sustainable model.

Key words: electrolytic manganese residue, detoxification, resource utilization, manganese resources, comprehensive utilization
