Mar 7, 2013 . Iron is always present in manganese ores, and the re- duction of iron oxides present in manganese ores runs parallel to reduction of the higher manganese oxides. According to the equations: 2. 3. 1 2Fe O. 3 2CO Fe 3 2CO. +. = +. (4). However, the most possible reaction is the indirect re- duction of higher.
More than 80% of the high-grade manganese ore (>35% manganese) is mined in South Africa, and also Australia, Brazil, Gabon, and, India, and, more recently, . Mn is utilized in numerous industrial processes including: (1) iron and steel production; (2) manufacture of dry cell batteries; (3) fuel oil additives and antiknock.
