Recovering Iron From Iron Ore Tailings And Preparing

Iron ore tailings IOTs are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this paper iron recovery from IOTs was studied at different points during a process involving pre-concentration followed by direct reduction and magnetic separation. Then slag-tailing concrete composite admixtures were prepared from high-silica residues.
