What are manganese ore fines and how are they sintered?

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."
