At the processing plant, the taconite is crushed into very small pieces by rock crushing machines. The crushers keep crushing the rock until it is the size of a marble. The rock is mixed with water and ground in rotating mills until it is as fine as powder. Separation The iron ore is separated from the taconite using magnetism.

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.

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 ...

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).
