Where is the ore? The premise is simple. Half of India's steel producers are in a bind. They allege that they can no longer access iron ore (the key raw material used to make steel) and are requesting the government to halt the export of the key raw material immediately. But the iron ore producers are disputing this claim and offering their own take on the matter.
