    Dec 01, 2018 Abstract. Iron tailings are the main component of industrial solid waste, and their resource utilization has attracted the attention of the whole society. Based on the introduction of chemical mineral composition of iron tailings, the comprehensive utilization status of iron tailings is analyzed. Some existing problems are put forward and relevant Suggestions are given.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.
