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 always preferred.
