Tailings are solid wastes of the ore beneficiation process in the extractive industry and are available in huge amounts in some countries. This paper reviews the potential utilization of tailings as a replacement for fine aggregates, as supplementary cementitious materials (SCMs) in mortar or concrete, and in the production of cement clinker.

Utilization of mine waste rocks and tailings in concrete as aggregates will help in sustainable and greener development. The literature shows the potential use of iron ore tailings as a replacement of natural fine aggregates. As natural sand reserves are depleting day by day, there is a need for substitution for sand in concrete.

Researchers worldwide have carried out a rigorous study on the recovery of chromite from tailings, considering the low quantity of Cr (T) and Fe (T) in the ore. These processes are partially successful due to the further assimilation of waste in the form of tailings.

The results demonstrate that the slag formed during the melting of silicate–carbonate refinement tailings can be used in the cement industry as an additive and when backfilling mine workings as a filler in backfill mixtures. A large share of the global gold reserves is concentrated in technogenic waste [1].
