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 …

Hence, it can be inferred from the experiments that breaking of cancrinite and sodalite phases present in the red-mud system enhances the iron extraction. Also, the trend of increase in iron values with increase in magnetic intensity can be explained as more paramagnetic iron containing phases will get trapped with increase in magnetic intensity.

Iron, symbolized as Fe, is one of the most abundant and widely used metals on Earth. It ranks fourth among the elements in Earth's crust, making up about 5% of the total. Occurrence: Iron is too reactive to occur as a free metal in the Earth's crust. It is mainly found in minerals like hematite (Fe2O3), magnetite (Fe3O4), limonite (Fe2O3.3H2O), siderite (FeCO3), pyrite …

Hematite is easier to floated than magnetic, which could be separated by positive flotation. As the density of iron ore is much higher than that of gangue mineral, gangue mineral is more likely to attach to the than iron ore. Therefore, for the extraction of iron ore, reverse flotation is more advantageous than positive flotation.
