Reductive dissolution of goethite and pyrolusite in alkaline solution

The selective dissolution of pyrolusite (MnO₂) in presence of goethite (FeO.OH) in aqueous ammoniacal ammonium carbamate solution has been investigated; various reducing agents were studied, in particular sodium sulfite (Na₂SO₃) and hydrazine hydrate (N₂H₄.H₂O). Sodium sulfite was found to be an un...
