When separating the iron ore from the waste becomes too difficult, mining companies will dispose of the tailings in a dam. The chemical additive is added to slurry a semi-liquid mixture that contains valuable iron particles suspended in water and works by separating the iron ore from impurities in the slurry.
Characteristics of the tailings, transportation from beneficiation plants and disposal system are described. Studies on tailing slime have been carried out at iron ore mines in Orissa and the results are discussed. The tailings contain toxic elements and find their way into the water environment.

Earlier Iron ore tailings contain iron concentrations of around 45 or more. In future it may become economically viable to extract the iron content from tailings, and due to the high cost of land and environmental factors it is worthwhile attempting to minimize tailings volumes. Further RampD study was
beneficiation. The Indian iron ore tailings typically contain hematite, goethite and clay materials. The beneficiation of these iron ore tailings will not only improve the overall recovery of the process but also will reduce the amount of materials to be disposed of as gangue materials. The effective
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.
