4 and leaving a residue of purified manganese dioxide. [7] These two steps can be summarized as: MnO 2 + N 2O 4 ⇌ Mn (NO 3) 2 In another process manganese dioxide is carbothermically reduced to manganese (II) oxide which is dissolved in sulfuric acid. The filtered solution is treated with ammonium carbonate to precipitate MnCO 3.
