Manganese ore - type minerals
, natural mineral
formation, the content of manganese
which is enough for the cost-effective extraction of this metal or its compounds. The most important ore-forming minerals include: pyrolusite
MnO2
·H2
O (63,2% Mn), psilomelane
mMnO·MnO2
·nH2
O (45-60% Mn), the manganite
MnO·Mn(OH)2
(62,5% Mn), the vernadite
MnO2
·H2
O (44-52% Mn), braunite
Mn2
O3
(69,5% Mn), hausmannite
Mn3
O4
(72% Mn), rhodochrosite
MnCO3
(47,8% Mn), alignit
(Mn, Fe)CO3
(23-32% Mn), the manganocalcite
(Ca, Mn)CO3
(up to 20-25% Mn), rhodonite
(Mn, Ca)(Si3
O9
) (32-41% Mn), bustamite
(Ca, Mn)(Si3
O9
) (12-20% Mn).Manganese ore is divided into chemical and metallurgical. The first contain at least 80% of MnO2. They are used in galvanic cells, in the manufacture of glass, ceramics,mineral dyes, "manganese" (KMnO4). Ores containing less than 80% of pyrolusite, called metallurgical and are used in ferrous metallurgy. Manganese in the formalloys with iron (ferromanganese) and silicon (silicomanganese) is the production of rail and structural steel, alloyed alloys based on aluminium, magnesium and copper.
