Ore sorting involves identifying and removing waste and belowgrade ore to preconcentrate the process plant feed. It produces higher, more stable head feed grades that essentially 'preserve' the processing capacity for economic ore ore that holds higher value than the cost of processing. Ore sorting can reduce variability and deliver ...

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).

Iron ore mining is the process of extracting iron from its natural form, which is found in rocks and minerals. The process begins by removing the topsoil from the area to be mined. This soil is then replaced and compacted to make sure that there is no waterlogging or runoff. The next step is to drill holes into the rock, so that explosives can ...
