China has become the global largest producer and consumer of electrolytic manganese metal country. In the rapid development of electrolytic manganese industry,a large quantity of electrolytic manganese solid waste (EMSW) causes serious environmental problems.Due to EMSW is a sort of acid leading residue genera-ted from electrolytic metal manganese production,lots of pollutants with high concentrations,difficulty in dis-persion and low activity,the disposal of EMSW becomes the intricacy and central issue.The physic-chemical and environmental characteristics of EMSW are introduced.The current disposal,recovery of NH3-N and man-ganese from EMSW,and resource technology are summarized.The disadvantage and advantage of the technolo-gy prospect are discussed and forecasted.Aiming to practical recycling of EMSW,it is prerequisite to develop and conduct the resource technology with low cost,high consumption,large market demands,low risk and high market awareness.Finally,the resource technology of utilizing EMR to make construction materials may have good application prospect.
