Types of goethite from Quadrilátero Ferrífero's iron ores ...

2013-7-18  Quadrilátero Ferrífero's iron ores used in the sintering process correspond to mixes of hematitic and goethitic ore typologies. The ores have particle size mainly distributed in the range from 635 to 0105 mm. The goethitic typology comprises a low amount in these ore blends; however, it can be relevant in the reactivity during sintering.
