What are manganese ore fines and how are they sintered?

Dec 18, 2017  Fines are the fine particles of manganese ore created when crushing manganese rocks. The fines are heated to sinter them (make them stick together, or become “agglomerated”). “The mines produce a lot of fines,” Hockaday explained. “But they can’t sell them, as furnaces won’t buy materials that are too fine.”.

3 .1 Manganese ores used in pilot sintering There are different types of manganese ore, for example hydroxide types and carbonate types. In \ this research two typical types of manganese ore have been used. Type 1 is a carbonate ore , of which the main carbonate is calcium carbonate .

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.
