| titleOfInvention | IMPROVED METHOD FOR THE CONTINUOUS PRODUCTION OF ELECTROLYTIC MANGANESE DIOXIDE. |
| abstract | An improved method for the continuous production of electrolytic manganese dioxide by electrolysis of an aqueous solution of manganose sulfate-sulfuric acid containing 30 g/l or more of magnesium in the form of magnesium sulfate as impurity and compensating for the manganese consumed by supplying of a neutral aqueous solution of manganese sulfate prepared by extracting magnesium-containing manganese ore as impurity with depleted electrolyte and sulfuric acid followed by neutralization and filtration, characterized in that the improvement consists in that the total amount of, or a part of the neutral manganese sulfate solution is concentrated in vacuo at a temperature between 40ºC and 60ºC to the concentration corresponding to saturation at 15ºC to that corresponding to 50ºC, and then it is cooled to 15ºC-25ºC, to give crystals containing sulfate of magnesium which is separated by filtration and the filtrate is fed to the ce Electrolytic lda to compensate the total amount or a part of the manganese consumed, whereby the content of magnesium in the form of magnesium sulfate in the electrolyte is kept at no more than 45 g/l.
