Introduction. Microbes tolerating manganese (Mn) are increasingly found in mining environment evolving several mechanisms to solubilize toxic metals by reducing their ion content or in using them as terminal electron acceptors (Gadd 2012 Gadd GM, Rhee YJ, Stephenson K, and Wei Z. 2012.
It is worth mentioning here that the share of manganese ore exported to total production of the ore had fallen from 88.86 per cent in 1970-71 to 20 per cent in 2002-03. The exports of manganese from India dipped to the lowest of 76 thousand tonnes in 1999-00 after which quick recovery was made in 2000- 01.

The brief introduction of manganese ore Mn is lithophile and it is always occurrence in the oxidate, hydroxide and carbonate. All the manganese ore can be classified into the manganese carbonate ore and manganese oxide ore. The manganese carbonate contain the magnesite, Calcium magnesite, tetalite and so on; The manganese oxide ore is include .
This is an introduction list that covers the most common carbonates minerals which are compounds of carbon dioxide (frequently called carbonic acid) with oxides of metals. In naming individual carbonates, the name of the metal is used; but if the name of the oxide of the metal is better known, as lime, for example, which is calcium oxide, the name of the oxide will be used instead of the name .
manganese demand from the U.S. Mint's introduction in 1999 of the so-called Golden Dollar was diminished because of the new coin's lack of popularity (Day, 2001). In 2000, domestic consumption of manganese ore increased by a marginal amount to 486,000 t, while corresponding yearend stocks increased by about 31% to 226,000 t. Because of the

Manganese ore is an in-homogeneous mixture of Pyrolusite, Psilomelane, Cryptomelane, and ferruginous minerals like Limonite, Goethite, Hematite, and shows a wide range of variation from high ferruginous ore to low ferruginous types.
Mn – Manganese Introduction Manganese is a member of the first row transition series of elements, consisting of Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu and Zn, and belongs to group 7 of the periodic table, along with Tc and Re. The element has an atomic number of 25, .
INTRODUCTION. Manganese is an essential element in the steel industry. Prior to 1870 the iron used was largely in the form of cast and wrought iron . high-grade manganese ore and iron ore, from manganiferous iron ore, and from manganiferous silver ore. GENERAL CONDITIONS.
In the steel, used as deoxidizer and alloy additives, is the largest amount of iron alloy. The general requirements of manganese ore containing is 40 to 50%, ferromanganese than greater than 7.Phosphorus and manganese ratio of less than 0.003. Before the smelting, the manganese carbonate should be roasted first, the powder must be sintered.
