tailing in mineral processing

Management of mineral processing tailings and ...

Feb 10, 2019  Mineral processing tailing and hydrometallurgical samples were manually sorted to remove the organic materials, glass and stones they sometimes contain. Sorting was followed by oven drying at 103 °C. The samples were then subjected to crushing and milling, when necessary, to ensure particle size reduction to 1 mm for ore concentration and ...

Tailings - Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) 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 and gravity
