Low-grade iron ore received from the West Singhbhum area of Jharkhand state in India was used to develop a beneficiation flow sheet to remove alumina (Al2O3) and silica (SiO2) from the ore to get iron (Fe)-rich product for steel plants. Mineral characterization showed that the main mineral constituents present in the head sample are goethite, limonite, hematite, quartz, …

However, the ultrafine particle size is the major hindrance to the beneficiation of plant tailings. Han et al. [60] reported different tungsten tailing deposits, shown in Table 3, comprising 96kt of WO 3 values across the globe. Further, it is also crucial to utilize the tungsten plant tailings as about 95% of the feed material report to tailing.

From Table 2.5, it can be seen that the major iron-bearing minerals are hematite and goethite. Among these, hematite is the most prominent iron-bearing mineral followed by Goethite. The gangue minerals are mainly kaolinite, gibbsite, and quartz. ... The beneficiation plant is designed to process less than 10 ...

Present investigation includes the magnetizing roasting of low-grade iron ore fines followed by grinding and beneficiation using magnetic separation. The hematite iron ore used in the investigation contains 53.17% T Fe, 10.7% SiO2, and 4.5% Al2O3. Powdered bituminous coal of 210 μm size with an ash content of 12.5% and fixed carbon of 54.25% was used as …
