Manganese does not occur as a native metal, but is found in nature in a great variety of combinations with other elements, whereby it forms a part of more than 100 minerals. Practically all of the manganese of commerce, however, is obtained from one or more of the first seven of the following minerals: Psilomelane, Rhodochrosite, Pyrolusite, Bementite, Manganite, Rhodonite, Wad, Hausmannite, Braunite, and Alabandite. 104 p.Additional Links
