However, there is a need for the site-specific estimation suited with the strata condition for estimation of optimum burden at the blast faces having huge variations in the rock types. Two different approaches have been used in this paper for computation of optimal burden of different rock strata of an Indian iron ore mine.
Iron ore is a rock from which the metal iron is extracted. About 98% of the world's iron is used to produce steel. Pure iron is an element and a soft grayish-white metal. Other than meteorites that fall from the sky, iron is never found by itself in nature. Most iron is part of minerals that contain other elements. Iron oxide is the …
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).
