The ban on iron ore exported from the state of Karnataka is having downstream effects on the supply of Indian steel, according to a story today in The Hindu Business Line. Quoting sources in the Bellary-Hospet region, the website says before the export of iron ore was banned in Karnataka in 2009, the state was producing about 42 million tonnes of iron ore and exporting 28 million tonnes. The following year, after the ban was implemented, 33.6 mt was produced, of which only 7.4 million tonnes was exported. But if all the iron ore pellets were used for sponge iron, pig iron and steelmaking, 41 million tonnes or iron ore would be required, or 33 million tonnes if the mills run at 80% capacity, leaving a significant supply shortfall, Hindu Business Line explains.
