OverviewRubbishErosionSinkholesWater pollutionEffect on biodiversityAquatic organismsTerrestrial organisms

Mining processes produce an excess of waste materials known as tailings. The materials that are left over after are a result of separating the valuable fraction from the uneconomic fraction of ore. These large amounts of waste are a mixture of water, sand, clay, and residual bitumen. Tailings are commonly stored in tailings ponds made from naturally existing valleys or large engineered dams and dyke systems. Tailings ponds can remain part of an active mine operation for 30 40 years. This allows for tailings dep
