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 …

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.

Cost analysis of iron losses due to an ore beneficiation and a scrap upgrade. The value of iron lost in an extra beneficiation operation is shown in Fig. 11 for three hypothetical cases A-C for tailing grades of (A) 10% Fe, (B) 15% Fe and (C) 20% Fe, which all contain 70% SiO 2. Data from the calculations are given in Table 12. The iron content ...
