Unlike iron, manganese does not readily form sulfides, and is only insoluble in its oxidised form. Primary manganese ore includes a wide spectrum of Mn-carbonate and oxide minerals, in which Fe is frequently present as an isomorphic mixture with Mn (Kuleshov, 2011). Redistribution of the manganese commonly happens during diagenesis, which is s ...
