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.

The detailed study of chromite ore beneficiation processes reveals that the opportunities still exist to recover chromite values from the low/sub-grade ores and tailings using the conventional beneficiation processes.

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].

Cement Production: In cement kilns, raw materials like limestone are heated to produce clinker, the key component in cement. Chromite-based refractories are used to line these kilns, ensuring that the high temperatures …

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 …

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.

Metallurgical fine chromite tailings can be upgraded to foundry sand specification, with dry size classification and magnetic separation. Chromite FeCr2O4 is a heavy mineral, specific gravity …

tailings. A pilot-scale Longi-Multotec LGS 500 vertical ring WHIMS unit was successfully used to upgrade chromite by 6–14% with a recovery of 44–62% at 0.4 T, and by 4–6% with a recovery of 55–72% at 1.3 T. A horizontal ring WHIMS of comparable size was not available for testing.

Uses of Chromium - Buzzle, ... has found a variety of industrial uses, ... chromite and chromium oxide an ideal refractory material. They have found applications in blast furnaces, cement ...

For this purpose, the tailings were partially replaced with the fine aggregate by the weight at 0, 10, 20 and 30% proportions by weight in the ready-mixed concrete mixtures.

Metallurgical fine chromite tailings can be upgraded to foundry sand specification, with dry size classification and magnetic separation. Chromite FeCr2O4 is a heavy mineral, specific gravity 4.5 - 4.8, containing iron and chromium 1.

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.
