  • 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 , 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.
