The production of iron from its ore involves a redox reaction carried out in a blast furnace. The furnace is filled at the top with the iron ore oxide most commonly hematite ((Fe_2O_3)) but can also magnetite ((Fe_3O_4)), carbon called coke and limestone ((CaCO_3)). ... As the process continue the molten iron flow down through the furnace ...

The capacity increased from 20.70 in 2010 to 37.4 Mt/year. This has been necessitated by a drop in iron ore production through bans on production as a result of illegal mining detected in iron ore-producing states like Karnataka and Goa and imposed caps on production on well-known iron ore-producing belts of Orissa.

ABSTRACT. The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet.
