process of iron ore concentration

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 preconcentration followed by direct reduction and magnetic separation. then, slagtailing concrete composite admixtures were prepared from highsilica residues.
