Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, …

For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is processed further and pelletised for use in direct reduced iron (DRI) steelmaking. In the processing stage, the mined material is transformed into usable raw material.
