presentations on mineral processing of mine tailings

Management of Tailings and Waste-Rock in Mining Activities. Mineral processing wastes are available from mining and mineral processing operations, most of which are located near the mine source and operated by mining companies. The quality of mineral processing wastes can vary widely and is highly dependent on the specific source.

Tailings Management Mineral Processing Extractives Hub

Mineral Processing. 8. Tailings management. Disposal of Tailings is one of the largest environmental impacts of those mines where tailings are produced, especially gold, copper and nickel. The design, construction, operation and maintenance of tailings dams is one of the key concerns of mine management and of governments of host countries.

Tailings

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water
