Abstract: To investigate the new technology for electrowinning of manganese dioxide using Ti-Ru anode from chloride solution, effects of electrolyte temperature, current density and electrolyte composition on current efficiency of MnO2, cell voltage and product quality were examined by aqueous electrolysis with constant electric current. Experimental results indicated that the current efficiency of MnO2 is 96% with cell voltage 2.0 V, MnO2 content 92.32% and the crystal structure of MnO2 in product is γ-MnO2 under the conditions of 75°C, 100 A/m², ρ(Mn²⁺)=50 g/L and ρ(HCl)=10 g/L. Ti-Ru anode for eletrowinning of manganese dioxide from chloride solution was verified available to ensure the product quality up to the standard for electrolytic manganese dioxide and electrolyte temperature is 75°C, lower than that in sulphate solution system (95°C).
