Manganese Ore - an overview ScienceDirect Topics

Santanu Chakraborty, in Treatise on Process Metallurgy: Industrial Processes, 2014. 5.3.7 Manganese Ore. Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions.
