A critical review on metallurgical recovery of iron from iron …
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, the global annual …
