Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were ...
Tailings are also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra-cone (terrikon). Examples Sulfide minerals. The effluent from the tailings from the mining of sulfidic minerals has been described as "the largest environmental liability of the mining industry".
Tailings dams usually only hit the headlines when they fail, resulting in the loss of life and catastrophic environmental damage. As a result, the proper design, management, construction, and monitoring thereof are vital, writes Nicolaas C Steenkamp.

16.2.1 Tailings Dams. The design, construction, and operation of tailings dams is a major consideration for most new mining projects, as well as for many existing operations (Vick, 1984). It is economically advantageous to site the impoundment close to the mine, but this imposes limits on site selection.

most important gold mining areas in the world. It is, however, replete with gold mine tailings which have contributed significantly to water pollution as a result of AMD. Water quality is affected mainly by mine tailings and spillages, especially from active slimes dams,
A conventional impoundment is a surface retaining structure designed to store both tailings and mine water, with the aim of reclaiming the water for use in the processing plant as required. There are principally two types of surface impoundments, a water retention type dam, and a raised embankment that has many configurations (Vick 1990).

dams are consequently designed and constructed without intervention on technical aspects by the authorities. However the Swedish dam owners in general have been aware of their responsibility and used the knowledge and experience available at each time. They have also supported research and development in the field of dam design and management.
