Brazilian Iron Ore and Production of Pellets - Semantic Scholar
2018年6月1日 ABSTRACT Brazil is the second-largest producer of iron ore in the world. Brazilian richer superficial deposits are composed of brittle material with fine texture and significant amounts of fines are generated during mining and transport. Another type of ore found in this country is the itabirites that have lower iron contents. Beneficiation and concentration
