    A Study on High-Grade Iron ore Beneficiation to Reduce ...

    May 21, 2020  Iron ore pellets are largely characterized by inherent physical and chemical properties of the ore. Alumina and silica play important roles in determining the productivity of a Blast Furnace. On average, one percent increase in iron content improves productivity by 2% and reduces coke consumption by 1%. Therefore higher iron ore feed content to blast furnace is
