Increased mining activity of iron ore has led to the generation of voluminous wastes of various nature, especially during the different stages of its extraction and production. The improper disposal of such waste causes negative impact on the environment. One such waste which is generated during the beneficiation process of iron ore is waste iron ore tailings, which is also termed as IOT.
India was ranked in fourth position among the iron ore producing countries in the world in the year 2009 (MoM, 2010). The country has an iron ore reserve of billion tons,
