What are manganese ore fines and how are they sintered?

18/12/2017  December 18, 2017 By Staff Editor. 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.”.

SINTER - F2. HIGH GRADE ORE . Manganese – symbol Mn – is the fourth most used metal in the world (after iron, aluminium and copper). Manganese is never used in its own right (as a pure metal), but it’s an important raw material for many applications. The final market for over 90% of all Mn ore produced is steelmaking. Ore is transformed into ferroalloys (silico-

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. The requirement of manganese ore for VSP was
