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.”

Jun 29, 2021 Sintering and pre-reduction have long been seen as energy-saving mechanisms for smelting (Tangstad et al., 2001), but in their current forms, make use of coal-powered electricity. Concentrated solar power (CSP) has therefore been considered for sintering and pre-reduction of Mn ore fines (Hockaday et al., 2018, 2019).

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.
