Dismissing the appeals of the revenue the Court held that the assessee purchased run-of-mines, which included a lot of impurities; it was crude ore, practically of no use unless it was processed and made suitable for its intended end-use. Iron ore concentrates were manufactured by the process of magnetic separation. It essentially amounted to manufacture or processing. The assessee was entitled to the benefit under section 10B of the Act. (AY. 2008-09, 2009-10)
