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.

Hydrogen reduction of iron oxide is an endothermic reaction that requires external heat input into the system such as preheating the iron ore. When magnetite iron ore is used, it becomes oxidized in a preheat process. Based on our previous study, the raw magnetite iron ore could not be completely fluidized at the temperature range of 600800 °C.

Figure 3 shows a comparison of the IEA and WSD views and the related iron ore demand of between 400 and 600 mt by 2050, compared to about 160 mt in 2019. From the quantitative perspective, iron ore supply should not be an issue, with BF iron production falling from just under billion tonnes in 2019 to 665 mt by 2050 per IEA's SDS (see Figure 1).
