A conventional tailings pond is designed to store both the solid and the water from tailings. Here, the solids segregate and settle, and process water is stored and recovered. A thickened tailings or paste disposal area is designed to store solids and a little excess water. Recovery of process water is carried out in the thickener before

Treatment of Gold Tailings in High Rate Thickeners

In 1988, a CIP gold treatment facility was installed at the Cosmo Howley gold mine in the Northern Territory. The nominal design tonnage of the facility was 1.2 Mtpa, and it was decided to include a 15 m Supaflo tailings thickener, based on bench scale testwork which indicated a throughput of 0.8 t/m²h to achieve an underflow density of 55 w

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

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were
