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. This would ensure much more consistent manganese content in the hot metal.

What are manganese ore fines and how are they sintered?

Dec 18, 2017  Once the fines are sintered, they then go to a blast furnace or an electric arc furnace, to smelt the manganese iron into manganese alloys. It is here that fines would be a big risk for literally gumming up the works or even causing explosions. In the blast furnace, hot gases are produced by the reduction reactions.
