    Biological and chemical processing of lowgrade manganese ores

    Jan 01, 1990 Leaching of manganese with aqueous SO 2 has been investigated at a laboratory scale by percolation at room temperature as a function of acid concentration solution flow-rate and time. The critical parameters were ascertained to be pH and redox potential in order to ensure the best conditions for the dissolution of MnO 2.With the proper choice of the process variables, maximum manganese ...
