As high-grade iron ore deposits are gradually being depleted, more difficult-to-process ores such as goethite-rich, low-grade iron ores and tailings are now being processed. These ores often contain impurities and require some form of beneficiation in order to achieve the typical grades required for sale to downstream steel producers.

Beneficiation techniques occasionally result in more energy-effective iron and steel production. For instance, employing higher-grade iron ore lowers the amount of energy used in the blast furnace, lowering greenhouse gas emissions. Figure 1 shows work flowchart for beneficiation process followed in the present investigation. The ore …

Magnetization roasting followed by magnetic separation is considered an effective method for recovering iron minerals. As hematite and magnetite are the main concomitant constituents in iron ores, the separation index after the magnetization roasting will be more optimized than with only hematite. In this research, the mechanism of the …
