Electrolytic manganese slag refers to the filter residue produced in the process of manganese electrolysis. Generally, the filter residue is acidic hazardous substance. At present, the main method for the manganese slag is to carry out open-air treatment, which can seriously pollute the environment and occupy a large amount of land area for a long time. Therefore, stacking treatment of the electrolytic manganese slag has become a big problem in electrolytic manganese slag industry. The research shows that the electrolytic manganese slag contains a lot of available valuable substances and has great recovery value. In this paper, the background of electrolytic manganese slag, the recovery method of valuable elements, the recycling technology of electrolytic manganese slag and the removal of ammonia nitrogen, heavy metal ions and sulfur from electrolytic manganese slag are reviewed. The separation and recovery technology of electrolytic manganese slag mainly includes magnetic separation method, water washing method, ammonium salt roasting method, leaching method, bio-leaching method, and electrochemical methods. Through the analysis of some valuable elements of the existing manganese slag, the purpose is to realize the resource utilization of the electrolytic manganese waste slag, so as to "turn waste into treasure", which is that the electrolytic manganese waste slag can be turned into valuable, thereby reducing the water pollution, soil pollution and air pollution caused by the electrolytic manganese slag. It is hoped to provide some references for the comprehensive resource recovery and utilization of electrolytic manganese slag. Therefore, the relevant research on the resource utilization of electrolytic manganese slag is of great significance.
