Manganese ores can be carbonates, usually rhodochrosite but sometimes kutnahorite, or various silicates and oxides, the most common being braunite, bixbyite, and hausmannite [see table of common minerals]. The carbonates carry useful isotope signals for C and O [see stable isotopes of Mn deposits].
Manganese Ores. natural mineral formations with sufficient manganese content to make economically feasible extraction of the metal or its compounds. The most important ore minerals are pyrolusite, MnO2 ( percent Mn); psilomelane, m H2O (4560 percent); manganite, MnO2Mn.
It oxidizes readily at about 933 K (660 C). Vanadium has good structural strength and a low fission neutron cross section, making it useful in nuclear applications. Although a metal, it shares with chromium and manganese the property of having valency oxides with acid properties. Common oxidation states of vanadium include +2, +3, +4 and +5.
The MineDop manganese ore's main characteristics include a high grade of manganes depending customer demands and wide grain size distribution and high degree of oxidation of the ore which makes it possible to decrease energy consumption and provide the yields during its use.
