Ti/Ti₄O₇ Anodes for Efficient Electrodeposition of Manganese Metal and Anode Slime Generation Reduction.

ABSTRACT: Preventing lead-based anodes from causing high-energy consumption, lead pollution, and harmful anode slime emission is a major challenge for the current electrolytic manganese metal industry. In this work, a Ti₄O₇-coated titanium electrode was used as anode material (Ti/Ti₄O₇ anode) in manganese electrowinning process for the first time and compared with a lead-based anode (Pb anode). The Ti/Ti₄O₇ anode was used for galvanostatic electrolysis; the cathodic current efficiency improved by 3.22% and energy consumption decreased by 7.82%. During 8 h of electrolysis, it reduced 90.42% solution anode slime and 72.80% plate anode slime formation. Anode product characterization and electrochemical tests indicated that the Ti/Ti
