SPOTLIGHT Iron Ore and Manganese Ore Metallurgy 2011
2012-7-13 was the first conference on iron ore andmanganese ore metallurgy to be held in South Africa.South Africa has extensive iron ore and manganese oreresources, and globally it is an important producer andexporter of these ores. South African iron ore supports thelocal iron and steel industry and South African manganeseore supports the local ferromanganese industry. There are anumber of iron ore and manganese ore mines in operation, aswell as a number of projects being considered fordevelopment, greenfield mines, and brownfield expansions ofexisting mines.

Direct Reduction of Mixtures of Manganese Ore and
2016-12-13 This paper presents recent results of direct reduction investigation of different combination of blends of manganese ore, iron ore and coal at the Department of Ferrous Metallurgy (IEHK) of RWTH Aachen University. A mixture of iron and manganese ore in a ratio of 75/25 is a good raw material for steelmaking of high Mn‐alloyed grades.

THE ROLE OF METALLURGY IN ENHANCING
2013-8-26 Manganese •Manganese ROM ore undergoes crushing mainly followed by processing using DMS and gravity concentration. •The manganese rich product is mainly smelted in electric furnaces to different grades of ferromanganese. Sometimes this is preceded by sintering of the manganese rich product. •The ferromanganese is used for alloying with steel.
