LINE FOR PRODUCTION OF ELECTROLYTIC MANGANESE DIOXIDE Russian patent published in 1998 - IPC

FIELD: equipment for production of manganese compounds, particular, electrolytic manganese dioxide. SUBSTANCE: the offered production line includes installed successively in production process flow and interconnected by means of transportation: module of leaching of manganese-containing raw material, module for separation of liquid phase from solid one and module of electric synthesis of manganese dioxide. Leaching module is made in form of, at least, two devices of electrochemical leaching of higher oxides of manganese interconnected to form closed circuit of pipelines of countercurrent transportation of manganese-containing raw material and leaching solution. Module of manganese dioxide electric synthesis is connected with tail device of electrochemical leaching by pipeline transporting the spent electrolyte. EFFECT: higher efficiency. 1 dwg
