Recovery of pure MnSO4∙H2O by reductive leaching of

Sep 14, 2011Manganese leaching and recovery from pyrolusite ore, was investigated by using H 2 SO 4 as a leachant and H 2 O 2 as a reducing agent. The effects of agitation, H 2 O 2 concentration, H 2 SO 4 concentration, liquid/solid mass ratio, leaching time and reaction temperature on manganese recovery were studied. The optimal leaching conditions were determined as 4.0 M H 2 SO 4 and 0.8
