Iron is the most abundant element on earth but not in the crust. The extent of the accessible iron ore reserves is not known, though Lester Brown of the Worldwatch Institute suggested in 2006 that iron ore could run out within 64 years (that is, by 2070), based on 2% growth in demand per year. Geoscience Australia calculates that the country's "economic demonstrated resources" of iron currently amount to 24 gigatonnes, or 24,000,000,000 t (2.4×10 long tons; 2.6×10 short tons). A

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 1.3 billion tonnes in 2019 to 665 mt by 2050 per IEA’s SDS (see Figure 1).

2020.2.8 In this regard, Rath et al. used microwave roasting followed by magnetic separation to achieve an iron ore concentrate of 63–64% Fe with more than 80% iron recovery from an iron grade of 57% Fe. In addition to the advantage of a much lesser time of roasting, it was observed that, unlike the conventional route, the microwave roasting

2006.2.7 Iron ore usually consists of iron oxides and carbonates. Its most important mineral forms are magnetite (Fe 3 O 4 , 72.4% Fe), hematite (Fe 2 O 3 , 69.9% Fe) and siderite (FeCO 3 , 48.29% Fe). In Brazil, some ore that contains practically no other minerals can grade as high as 68% Fe, but the crude ore mined in Canada grades between 30
