Iron ore pelletizing plants play an important role in these two aspects. For low-grade iron ore, they should be beneficiated to improve the iron content. We usually grind up iron ore after mining and remove the useless part (tailings). Therefore, most of the iron ore that is sent into the steel plants has a fine particle size.
