Pellet makers, sponge iron and pig iron producers allowed to participate. : The upcoming phase of iron ore auctions in Odisha is likely to witness intense bids as pellet manufacturers, sponge iron players, and pig iron producers compete alongside steel companies. Odisha has hitherto put three iron ore blocks -- Ghoraburhani-Sagasahi, Kalamang West and Netrabandh Pahar -- for auction. All three were bagged by steel producers- Essar Steel, Bhushan Steel Ltd (now Tata Steel BSL) and Bhushan Steel & Power Ltd.
