In India, where iron ore processing is one of the major industries, the generation of tailings is estimated to be 10-25 % of the total iron ore mined, amounting to 18 million tons per year (Das et al., 2000). The tailings contain silica in high percentage (40-60 %, from various locations).

A typical ore body will contain a few percent of ore minerals—typically sulphide minerals like chalcopyrite or sphalerite—along with the minerals of the original rock (e.g., quartz, feldspar, amphibole etc.). Most ores also contain some other non-ore minerals (e.g., hematite) and some other sulphide minerals, especially pyrite (FeS 2).

The tailings dilemma Mine tailings are the waste byproduct left after extracting the economic fraction from ore. Although the exact composition varies according to the ore and processing methodology, tailings generally contain a significant water fraction alongside unwanted gangue material and chemical reagents.

Mine tailings are the waste material that remains after the economic fraction has been extracted from the mineral ore. Tailings consist of a slurry of ground rock, and water and chemical reagents that remain after processing. The composition of mine tailings varies according to the mineralogy of the ore deposit and how the ore is processed.
