If the M B Shah Commission's proposal for a complete ban on iron ore mining in Odisha is implemented, it may result in a fall of 11 million tonnes (mt) in the combined captive iron ore output of Steel Authority of India Limited (SAIL) and Tata Steel.

Earlier, iron ore mining was banned in Goa, after it was found norms related to the environment had been violated. The commission is finalising its recommendations on irregularities in iron ore mining in Odisha. If the commission suggests a blanket ban on mining, SAIL would lose four mt of captive iron ore output, while Tata Steel would lose seven mt of iron ore a year.
