摘要：
A rich manganese ore from Chalkidiki (Greece) was leached in aqueous SO2 solutions at atmospheric pressure and ambient temperature to extract more than 95% Mn after 10 min. Process conditions, such as SO2 concentration, time, pH, agitation rate, temperature and pulp density were investigated. Low impurities of iron in the pregnant solution were observed and the process seems to be attractive for manganese extraction from this ore.
