EMD is produced in a similar fashion as electrolytic tough pitch (ETP) copper: The manganese dioxide is dissolved in sulfuric acid (sometimes mixed with manganese sulfate) and subjected to a current between two electrodes.
EMD dihasilkan dengan cara yang sama seperti tembaga electrolytic tough pitch (ETP): mangan dioksida dilarutkan dalam asam sulfat (kadang-kadang dicampur dengan mangan sulfat) dan dikenakan saat ini antara dua elektroda.
