Process for the production of battery-grade manganese dioxide. Abstract Battery-grade MnO2 is produced by (a) treating a MnCl2 solution with Cl2 and Mg(OH)2 whereby obtaining a MgCl2 solution that contains a MnO2 precipitate; (b) allowing to digest the precipitate in the MgCl2 solution in presence of Cl2 under pressure; (c) separating the digested precipitate from the solution; and (d) washing and drying the precipitate. Owing to step (b), operating conditions in step (a) may be such that a concentrated MgCl2 solution is obtained, which is important for the further processing of that solu- tion by pyrohydrolysis.
