      Tailings are a type of rock waste from the mining industry. When a mineral product is mined, the valuable portion is usually embedded in a rock matrix called ore. Once the ore has been stripped of its valuable minerals, sometimes through the addition of chemicals, it is piled up into : Frederic Beaudry. hart () for the dewatering of sand washery tailings, with vertical electrodes placed from a pontoon, where dewatering was achiev ed using only 1 kWh/dry tonne.

Additional Physical Format: Online version: Rickel, R.L. (Rod L.). Sand bed dewatering of alumina miniplant tailings. [Avondale, MD]: U.S. Dept. of the Interior. Part of the investigation evaluated the sand bed dewatering technique for disposal of alumina miniplant tailings as a means to increase consolidation rates and contain effluents.

The technique employs a bed of sand resting on an impervious bottom. The tailings slurry is impounded over the sand layer and is dewatered through bottom drain piping.

Final Tailings Dewatering – the only waste product is now a filter cake with dry solids content of 80%, effectively eliminating the requirement for tailings dams; Dewatering concentrate - The filter press can also be applied in the processing of a variety of ores for the dewatering of the concentrate in preparation for further processing.

Outotec solutions for tailings dewatering Optimized offering with large portfolio for different demands of tailings treatment. Currently Tailings are a composite of all processing plants wastes and represent varieties of mineralogy with a wide range of particle sizes rheology, process water, excess reagents and spillage.

The project was awarded $K to establish the technical feasibility of using the Inline Dewatering Process to dewater tailings to a predetermined density before discharged.

Results: The Inline Dewatering Process uses the concept of cross flow filtration (CFF) whereby a slurry of tailings, flowing through a special pipe, is dewatered. Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an gs 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. Environmentally, the past years have experienced a very positive approach to improving the quality of effluents discharged from mining and milling processes, and ultimately the quality of seepage from the tailings impoundment area into the environment.

This book assembles all the various aspects of the process and of tailings management which have an impact on the environment, thus. tailings, and oil sands tailings are not included. Laboratory and field characterisation of tailings properties and behaviour has been reported in the literature by several others.

Underground mining is conducted through adits or shafts by a variety of methods that include room-and-pillar, block caving, timbered-stope, open-stope, shrinkage-stope, sublevel-stope, and others.

Waste removal is proportionately much less in underground than in surface mining, but it still requires surface waste disposal areas. One of the challenges faced by the oil sand industry is the dewatering of mature fine oil sands tailings (MFT) due to the low permeability.

Vacuum pressure or electrokinetic (EK) dewatering is effective to meet this objective. This research was focused on the experimental study and analytical modelling to explore the influence of combined vacuum and EK treatment on : Rui Zhang.

However, it still appears relevant as a target for the development of oil sands tailings dewatering strategies. The production of 1 tonne of synthetic crude oil with the Clark hot water extraction process requires mining tons of oil sands and uses tons of water (Allen, ).

The waste from this process is tons of tailings with an Cited by: 5. The appropriate management of oil sand tailings requires a reduced environmental footprint of the waste containment facilities. This study models the short-term dewatering behavior of a 10 m deep deposit.
