Abstract: Electrolytic manganese slag is a kind of filtered acid residue produced in the process of electrolytic manganese production.In recent years，the rapid development of electrolytic manganese industry brings great benefits，but at the same time，it also causes environmental pollution problems.The resource utilization of electrolytic manganese slag has become an urgent problem to be solved，which has become a hot spot in the field of electrolytic manganese metal industry and environmental protection.The current research progress of comprehensive utilization of electrolytic manganese slag was introduced，and shortcomings of existing methods were summarized.Some ideas for the research and application of electrolytic manganese slag were also put forward，hoping to provide a reference for the comprehensive utilization of electrolytic manganese waste residue in the future.

Key words: electrolytic manganese slag, resource utilization, manganese recovery
