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. Based on the ...
