Magnetic separation could be carried out at a magnetic intensity as low as 750 gauss by increasing the quantity of reductant and by increasing the temperature and time as well. Red mud and coal dust (CD) in proportions (5%, 10%, 20%, and 40%) were mixed properly and calcined for 3 h at 600 °C, 700 °C, and 800 °C respectively.
