With the exhaustive processing of the known reserves of hematite from Iron Ore Quadrangle (Minas Gerais-Brasil), there will be no shortage of granules in the not too distant future. Therefore, there is an expectation that the ore mined will have higher levels of phosphorus. This expectation is not reflected in publications of national authors, thus translating into a risk for the activity.
