Synthesis of magnetite powder from iron ore tailings ...

Jul 26, 2010· Iron ore tailing—a waste material of mineral beneficiation plants, is used as a source of iron for synthesizing magnetite powder. Iron ore tailings containing 15.98% Fe 2 O 3, 83.36% SiO 2 and 0.44% Al 2 O 3 have been subjected to HCl digestion on a hot plate to extract the entire amount of Fe 2 O 3 as FeCl 3.A portion of extracted FeCl 3 solution has been used to convert it to FeCl 2 via ...
