[Ferro-alloys.com] Electrolytic manganese dioxide (EMD) is mainly used to produce dry battery. Electrolytic manganese dioxide (EMM) is closely related to EMD in production. They are both deep-processed products of Mn ore. To be exact, MnCO3 ore could be smelted to produce EMM or EMD. Their crafts are quite similar before the electrolytic process. Therefore, many enterprises produce the two products at the same time. For example, Xiangtan Electrochemical Scientific Ltd is the largest EMD manufacturer of the world. Its annual capacity of EMM is as much as 15,000 mt.  Guangxi Jingxi County Yizhou Manganese Industry Co., Ltd., Guangxi Non-Ferrous Metals Group Huiyuan Manganese Industry Co., Ltd. and CITIC Dameng Mining Industries Ltd could all produce the two products.
