Abstract: Electrolytic manganese slag belongs to the class Ⅱ general industrial solid waste. With the increase of the output of electrolytic manganese residue and the improvement of environmental requirements, reasonable treatment methods for the electrolytic manganese residue are catching more and more attention. Based on the utilization level of electrolytic manganese slag, the treatment methods of electrolytic manganese slag can be divided into three aspects which are safe storage, harmless treatment and resource utilization, respectively. According to the technical characteristics, the treatment technology of electrolytic manganese slag can be divided into four categories which are safe storage technology, dry treatment technology, fire treatment technology and wet treatment technology, respectively. According to the characteristics of electrolytic manganese slag treatment technology, the paper discussed the related research progress in recent years in order to find feasible solutions in technology, economy, market capacity or absorptive capacity and standard requirements.
