Influence of the material properties of iron ore sinter

Abstract The effects of feed properties on the granulation of iron ore sinter feed have been studied using simplified sinter mixes. A measure of granulation effectiveness x0.5 has been defined as the particle size at which half the particles act as adhering particles and half as nuclei particles. High values of x0.5 correspond to large mean granule sizes.

Manganese Ore an overview ScienceDirect Topics

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.
