MHO Metallurgie Hoboken-Overpelt 1


MHO Metallurgie Hoboken-Overpelt 1 : A process for extracting manganese and other metals from nodules from the sea bed by extraction with hydrochloric acid: MnO2 + 4HCl = MnCl2 + 2H2O + Cl2. The chlorine formed in this stage is re-used in a subsequent stage where it oxidizes the manganese (II) to manganese (IV), which precipitates as MnO2. (Check source for accuracy of chemical formula)
