Whilst demand for some resources such as coal is falling, other resources such as copper are seeing increasing demand as new products and technologies require different materials.

Use of Evaporation Ponds in the Mining Industry

Tailing ponds are some of the most well-known and common harvesting pits that rely on evaporation. Many mining methods still relying on powdered rock that is tricky to separate from minerals or metals. Yet, tailing ponds also generate highly acidic and contaminated wastewater. The majority of tailing ponds around the world are natural pits with no liner, leading to

Phytostabilization of Mine Tailings in Arid and Semiarid

200831What prevents the natural revegetation of mine tailings? It is generally a combination of factors beginning with metal toxicity. Tailings are characterized by elevated concentrations of metals such as arsenic, cadmium, copper, manganese, lead, and zinc (1–50 g/kg) ( Boulet and Larocque 1998; Bradshaw et al. 1978; Walder and Chavez 1995 ).

Mine Tailings

20101215Most modern hardrock metal mines dispose of tailings as a wet mud, held in pits lined with clay or a synthetic liner. Many mines put the tailings back into the original mining pit. Some large mines use entire existing valleys sealed off with earthen dams, and others store tailings in natural lakes. In most cases, disposal pits are covered with water, forming an

Tailings Management

Tailings are a by-product of mining, consisting of the processed rock or soil left over from the separation of the commodities of value from the rock or soil within which they occur. If not managed responsibly, tailings can pose potential risks to human health and safety, the environment, infrastructure, and to mining companies themselves.
