Section snippets Definition of tailings. Tailings are mixtures of crushed rock and processing fluids from mills, washeries or concentrators that remain after the extraction of economic metals, minerals, mineral fuels or coal from the mine resource (e.g., Fig. 1a; Hudson-Edwards et al., 2001, Younger and Wolkersdorfer, 2004, Lottermoser, 2007).

A tailings dam is a tailings embankment or a tailings disposal dam. The term "tailings dam" encompasses embankments, dam walls or other impounding structures, designed to enable the tailings to settle and to retain tailings and process water, which are constructed in a controlled manner. A tailings impoundment is the storage space/volume ...

conventional tailings include cross-valley and paddock (ring-dyke) impoundments, where the tailings are behind a raised embankment(s) that then, by many definitions, become a dam, or multiple dams. However, a tailings facility can have an embankment function like a dam during some portion of its life cycle but not during another (e.g. closure).
