Falling prices for iron ore with lower quality than 60 % Fe have led increasingly to the design of iron ore beneficiation lines. General problems of water scarcity and risks with tailings dams have led to the focus shifting to dry beneficiation technologies. In the following article, current developments are examined and case studies referenced.

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).

Iron ore beneficiation is the process of improving the quality of iron ore by removing impurities and increasing its iron content. It is necessary to reduce alumina and silica in the feed. The process improves the chemical, physical, and metallurgical characteristics of the ore to make it a more desirable feed for iron-making furnaces.

Mining (extraction), beneficiation, and processing of iron ore produces iron and steel. Mining is defined as removing ore material from a deposit and encompasses all activities prior to beneficiation. High grade iron ores (iron content greater than 62 %) are simply crushed, screened and shipped directly to the iron making unit (e.g. blast furnace).
