The country has a growing iron orepelletizing sector, with Brazilian mining and metals giant Vale having commissioned its iron ore beneficiation plant in early 2012 with the objective of servicing ore imported from Brazil. This plant consists of two processing lines, each having a capacity
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. Indian ...
