Global mining company Rio Tinto Limited operates a fleet of heavy haul iron ore trains 24 hours a day from its 16 mines to four port terminals overlooking the Indian Ocean. To increase their operational capacity and reduce transportation time, Rio Tinto realized that driverless (GoA4) operation of its trains was the way to achieve this.

These steps vary with the respective raw material—for example, ore processing consists of crushing and grinding. For bulk material ( iron ore) once reconditioned, the product is stacked in stockyards and then it is transported to the port.

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 is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
