A process for the recovery of Mn from a waste of spent alkaline batteries using sulfuric acid and hydrogen peroxide has been investigated. The proposed procedure consisted of mechanical separation of metal-containing particles and a leaching process. The effects of leaching agent, reaction temperature, time and pulp density for the leaching were also examined. Crushing and sieving of the spent batteries resulted in satisfactory separation of particle size from the waste. 99% Zn and 97% Mn were successfully extracted from the spent battery powder by the leaching at 60°C for 60 min with the addition of hydrogen peroxide as a reducing agent. The hydrogen peroxide addition led to almost doubling Mn extraction compared to without it.
