Transforming iron ore processing
In the recent past, iron ore resources from Brazil consisted of relatively high-grade iron ore, commonly processed via multi-stage crushing/screening, gravimetric concentration, magnetic separation, and reverse flotation. However, the high-grade iron ore reserves are in decline, resulting in the need to process the lower grade itabirite iron ores.
