Sinter is the primary feed material for making iron in a blast furnace. According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace.

In addition, iron ore can be directly charged to the process in form of lump ore, pellets, and sinter [34]. The COREX process is a two-stage direct smelting process, consisting of: (1) a melter-gasifier, which melts the DRI and gasifies the coal; and (2) a DRI shaft furnace mounted above melter-gasifier, which reduces lump ore or pellets to DRI ...

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.
