Wet circuit iron ore processing generates slimes to the tune of 10 to 15 % of run-off-mine (ROM).In Dalli mines, which is processing iron ore through wet circuit, 0.7 MT slimes are produced per annum. About 14.5 MT of slimes has accumulated in the Hitkasa tailing pond. Fe content varies from 49% to 55% in the accumulated slime.

It is estimated that about 84% of total solid waste generation is in iron ore tailings (Fines/ Slimes), coal combustion residues (Fly Ash or Bottom Ash), and the remaining 16% constitute all others, including slag. The above wastes (Iron ore slime & Bottom ash/ Fly ash) are being used for landfilling and in few countries to get value …

Iron ore tailings (IOT), the predominant solid by-products of iron ore mining and refining, present significant environmental challenges due to their sheer volume. This paper endeavors to scrutinize the prospective deployment of IOT as an alternative to soft soil in the fabrication of controlled low strength materials (CLSM) for backfill applications.

Also, the ratio of IOT generated to that which is utilized is high, due to lack of advanced beneficiation techniques for low-grade ores in iron making process (Patra et al., Citation 2019), and hence, a large quantity of these tailings are dumped at the mine sites or tailing ponds. Therefore, there is a need to find alternative reuse techniques ...
