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.
