Abstract:The electrolytic manganese industry in China generates a large number of electrolytic manganese slag containing toxic components such as manganese and ammonia nitrogen every year. The traditional storage and disposal methods have great environmental risks, and its resource utilization is of great significance to the environmental pollution control of electrolytic manganese industry. The latest research progress of dry method, pyrogenic process and wet treatment technology of electrolytic manganese slag were systematically reviewed, the environmental risk points in the technology development were comprehensively analyzed, and the carbon emission in the process of resource utilization of related technologies was discussed in depth. Finally, combined with the development needs of the industry and the goal of "double carbon", suggestions were put forward for the priority development technology direction of electrolytic manganese slag resource utilization, carbon emission accounting during the process, and accelerating the market application of resource-based products, aiming to provide technical support for promoting the green and low-carbon transformation and upgrading of electrolytic manganese industry
