Iron Ore Sinter - an overview | ScienceDirect Topics

L. Lu, O. Ishiyama, in Iron Ore, 2015. 14.5 Conclusions. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics.
