Genetic Types, Classifications, and Models of Manganese

Jan 01, 2017 Genetic Types and Classification of Manganese-Ore Deposits. The scientific literature presents various classifications of deposits of manganese. In general plan, four genetic groups of deposits have been identified (see the works of A.G. Betekhtin, N.P. Kheraskov, N.S. Shatskii, S. Park, S. Roy, I.M. Varentsov, V.P. Rakhmanov, V.K. Chaikovskii

Manganese Ore Deposits

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].

PROPERTIES OF MANGANESE ORES AND THEIR CHANGE IN

properties of a manganese ore have a large influence on the technology and efficiency of the production of manganese alloys. The melting and reduction behaviour of ores are defined by their chemistry, mineralogy and physical properties, which change as the ore is heated in a reducing atmosphere in a ferroalloy furnace.
