Abstract Results of beaker scale and large laboratory scale experiments on the deposition of manganese from chloride electrolytes are reported for conditions where chlorine is the secondary anode product. Manganese concentration in the catholyte was found to be the most significant variable, with higher manganese levels (to 33 g Mn l−1) resulting in higher current efficiency (65–70%) and lower power consumption (5.5 kWh kg−1). Temperature (30–60°C) and current density (1.0–2.0 kAm−2) had opposing effects on current efficiency and power consumption. In the ranges studied, lower temperatures and higher current densities gave rise to increases in current efficiency and power consumption. The literature on the electrowinning of manganese from chloride electrolytes is reviewed and the anomalies in previous reports discussed.
