  • Pyrolusite

    Pyrolusite is a mineral consisting essentially of manganese dioxide (Mn O 2) and is important as an ore of manganese. It is a black, amorphous appearing mineral, often with a granular, fibrous or columnar structure, sometimes forming reniform crusts. It has a metallic luster, a black or bluish black streak, and readily soils the fingers.

  • Selective In Situ Leach Mining of Manganese Ores

    In pyrolusite hematite quartz ore a similar process is observed in which a residue of hematite and quartz was left unleached. In the case of a batch leach test of cryptomelane ore from the Emily District, the suspension of hematite and quartz was left in the flask after all the cryptomelane had been dissolved.

  • Manganese processing Encyclopedia Britannica

    The most important manganese ores are the oxides pyrolusite, romanechite, manganite, and hausmannite and the carbonate ore rhodochrosite. Rhodonite and braunite, both silicate ores, are frequently found with the oxides. Only ores containing greater than 35 percent manganese are considered commercially exploitable.
