Manganese Ore
Classification of manganese ore, ferruginous manganese ore, siliceous manganese ore, dioxide manganese ore and manganiferous iron ore is laid down by BIS vide specifications no. IS:11895-2006 (Reaffirmed 2008) Manganese ore is an important material in iron and steel metallurgy, where it is used both in the ore form as such and as ferro manganese. Manganese improves strength, toughness, hardness and workability of steel, acts as a deoxidiser and desulphuriser and also helps in getting ingots free from blowholes. About 90 to 95% world production of manganese ore is used in metallurgy of iron and steel. Manganese has no satisfactory substitute in is major applications.
Description
Manganese ore is silvery in colour and very hard and brittle in nature. It is always available in combination with iron, laterite and other minerals. Manganese in Alloy form is an essential input in steel making and is one of the most important metals in an industrial economy. Manganese of major commercial importance are: Pyrolusite (MnO - Mn about 63.2%) (ii) psilomelane (manganese oxide) containing water and varying amounts of oxides of Ba, K and Na as impurities; Mn commonly 45-60%) (iii) manganite (mn2O3H2O,Mn about 62.4%) and (v) braunite(3Mn2O3MnSiO3 - Mn about 62% and SiO2 about 10%) Indian manganese ore deposits occur mainly as metamorphosed bedded sedimentary deposits associated with Gondite Series (Archaeans) of Madhya Pradesh, Maharashtra, Gujarat, Odisha and with Kodurite Series (Archaeans) of Odisha and Andhra Pradesh. Also sourcing Imported Manganese Ore from origin of South Africa, Brazil, Gabon & Australia.
