Most iron and manganese deposits form directly from seawater, and, because of their redox sensitivity, are likely to respond to changes in the oxidation state of the oceans. Iron ore deposits have long been studied for evidence of effects of the evolving ocean atmosphere system.
Abstract The regionally metamorphosed syngenetic sedimentary bodies of manganese ores in the Sausar of Balaghat district, Madhya Pradesh exhibit a definite trend in the formation and transformation of manganese oxide phases with progressive metamorphism.
The evolution of the ore bearing sequence indicates that manganese mineralization occurred during the early stage of regression.The important Mn carbonate deposits hosted in the black shale series resulted from three main processes during formation: concentration in seawater, precipitation from seawater, and enrichment in the sediments.
Jan 01, 2017· The possibility of catagenetic manganese ore formation in connection with the Mangyshlak and Laba deposits has been expressed by V.N. Kholodov, V.I. Dvorov, and E.A. Sokolova. In this case, petroleum waters contain large quantities of carbon dioxide, methane, hydrogen sulfide, and other aggressive components.
Manganese has no satisfactory substitute in its major applications in metallurgy. In minor applications , zinc and sometimes vanadium are viable substitutes. Manganese is essential to iron and steel production by virtue of its sulfur fixing, deoxidizing, and alloying properties, as first recognized by the British metallurgist Robert Forester Mushet who, in 1856, introduced the element, in the form of Spiegeleisen, into steel for the specific purpose of removinWikipedia · Text under CC BY SA license
manganese "manganese deposits" "manganese minerals" "manganese ores" "Mn deposits" Manganese. Manganese is the ninth or tenth most abundant element in the Earths crust . Most of its industrial use is in steel making with a much lesser amount going into the production of batteries. It is very similar to iron in its chemical properties.
