  • Removal of Fe from fly ash by carbon thermal reduction

    Jun 01, 2017· A certain amount of reduced fly ash was weighed, grinded fully in a mortar, and mixed with water for magnetic separator to remove magnetic Fe by XCRS400300 magnetic separator made in China. After that, the residue was mixed with 4 mol/L HCl solution, and the mixture was heated at 90 °C for 2 h to provide enough reaction time.
