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.
