Beneficiation Low Grade Hematite E

The iron ore industry faces continuous pressure to reduce the process costs (e.g., grinding below 50 m to liberate the iron oxides from the gangue in low-grade ores. An ideal blast furnace feed should have about 65% of Fe and an Al2O3/SiO2 ratio of 1, in order to achieve optimized productivity and sufficient slag flow ability, respectively
