The fine particle size of the resulting iron ore concentrate is better suited to pelletising than sintering, which is why almost all US iron ore is pelletised. In fact, the physical properties of the local taconite deposits actually led Cleveland Cliffs to pioneer the iron ore pelletising process in the 1950s.Get Price
