【Abstract】 Results of beaker scale and large laboratory scale experiments on the deposition of manganese from chloride electrolyes are reported for conditions where fibrous electrolytic manganese dioxide is the anodic product. Anolyte and catholyte compartments were provided by dividing the cell with a porous porcelain plate. Graphite blocks were used as anode and stripts of titanium as cathode.The influence of various factors, such as current density temperature, concentrations of ammonium chloride and addittives on current efficiency of electrodeposition of metallic Mn have been studied. To produced one kilo-gram of metallic Mn as well as two kilo-gram FEMD an electric energy of only four to five kilowatt hour would be required. The current efficiency of electrolyzing metallic Mn arrives or surpasses the advanced level reported recently.更多还原
