Extraction and separation of manganese and iron from ...

2019-1-15  In the oxide type manganese ore, the manganese is often present in the insoluble form of Mn 4+ and iron often exists in the state of Fe 3+. In order to obtain soluble Mn 2+ , Mn 4+ must be converted into Mn 2+ , therefore, reductants are applied to reduce Mn 4+ into Mn 2+ during the acid leaching process (Named as direct reduction leaching).

Manganese Ore - an overview ScienceDirect Topics

Iron is always present in manganese ores, and the reduction of iron oxides runs parallel to the reduction of higher manganese oxides. At temperatures above 1150°C, reduced iron forms a liquid alloy, dissolving carbon and assisting in the reduction of manganese due to lower Mn activity in the metal phase.

2013-6-5  Iron is easily oxidized by atmospheric oxygen. Aeration provides the dissolved oxygen needed to convert the iron and manganese from ferrous and manganous (soluble) forms to insoluble oxidized ferric and manganic forms. It takes 0.14 ppm of dissolved oxygen to oxidize 1 ppm of iron, and 0.27 ppm of dissolved oxygen to oxidize 1 ppm of manganese.

PROPERTIES OF MANGANESE ORES AND THEIR CHANGE

2010-11-12  In the process of calcination of manganese ores in air, MnO2 was reduced to Mn2O3 and Mn3O4, while during calcination in a reducing atmosphere manganese oxides were reduced to MnO and iron oxides to metallic iron. Formation of a liquid slag in ores at equilibrium was predicted for Wessels, Groote Eylandt and Gabonese ores at 1200°C in air and 1000-1200°C in a reducing atmosphere. No liquid slag was predicted for equilibrium phases in CVRD ore.
