Tailings

The modern tailings designer has a range of tailings products to choose from depending upon how much water is removed from the slurry prior to discharge. The removal of water not only can create a better storage system in some cases e.g. dry stacking, see below but can also assist in water recovery which is a major issue as many mines are in arid regions.

Tailings

OverviewStorage methodsTerminologyExamplesEconomicsEnvironmental considerations and case studiesReprocessingPond reclamation by microbiology

Historically, tailings were disposed of in the most convenient manner, such as in downstream running water or down drains. Because of concerns about these sediments in the water and other issues, tailings ponds came into use. The sustainability challenge in the management of tailings and waste rock is to dispose of material, such that it is inert or, if not, stable and contained, to minimise water and energy inputs and the surface footprint of wastes and to move toward finding alternate uses.
