2020-10-28 Tailings are usually produced at some mineral processing and mine sits. In the mining, the most part of the mines are tailings whereas the extracted minerals are just small part of all fractions. After low-grade ores has been utilized, almost 99% of main materials may finally become tailing. Therefore, tailings contain large part of waste in mining

2019-10-16 Africa has the second largest ultimately recoverable resources (URR) of gigaton (Gt) iron (Fe) ore in the world. South Africa is among the countries in the world with high-quality iron ore deposits. The most significant sources of Fe ore in the African continent are hosted by the banded iron ore formation of Precambrian age with high-quality hematite (Fe2O3) bodies.
Mine tailings are the finely ground residue from ore extraction. The grain size of the tailings depends on the nature of the ore and the milling process. Size measurements (Robertson, 1994) of tailings from four mines in Ontario, Canada, indicated the tailings materials to be predominantly silt and fine to medium sand with <10% clay content.
2020-9-23 The presence of REEs in tailings of iron ore and apatite has been studied. REEs were found in fluorapatite, monazite, allanite (ce-bearing), xenotime (Y), light rare-earth element (LREE)-bearing epidote, and REE fluorocarbonates [88, 89]. Yang et al. investigated apatite vein-type REE from Mushgia Khudag, South Gobi, Mongolia.

Wastewater produced by the mining industry is also known as tailings. Tailings contain waste from the extraction processes, equipment washing water and the refining process. It is a sludge-like waste that contains a mixture of fine gangue particles, chemicals and water; and in many cases is stored in large facilities called tailings dams or ponds.
2016-1-21 1-87). No further grinding treatment was conducted in laboratory. The tailings were dried in oven at 100˚C overnight, cooled naturally, and then be characterized. The tailings was suspended in water (1:4 tailings to water ratio) slurried by stirring with an impeller stiand r-rer without adding any dispersant or adjusting the pH value. 2.2.
2020-3-27 If Karara Mining Limited’s iron ore mine had chosen a wet tailings storage facility, the tailings pond would have been roughly eight square kilometres, based on 30-year mine life. Karara is located in the Mid-West region of Western Australia in an area of water scarcity and so losing so much water to wet tailings
The treatment plants at Serra Leste (in Curionópolis) and the S11D complex (in Canaã dos Carajás) do not use water to treat the ore. At S11D complex, for example, the use of the natural moisture processing route allows water consumption to be reduced by 93% when compared to the conventional method of iron
2005-9-21 Fe(II) treatment of TM reduced the water-extractable total As to <10 microg/L as the Fe:As molar ratio increased from 0 to 8. The water-soluble As of Fe-treated tailings could be reduced to 10-30 microg/L also under conditions of intensive leaching. Stabilizing the pH with CaCO3 resulted in consistently higher As release.
2016-5-7 Pyrite has long been used as a source of sulphur, and its recovery as a by-product from the flotation of certain base metal ores is a well established practice. Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite. In many instances these tailings

2021-3-17 The beginning of the tailings filtration operations in Vargem Grande is another step in stabilising iron ore production and on the way to the return of the production capacity of 400 Mt/y at the end of 2022, says Vale. The planned Vale
The experimental results in Fig. 5a show that as the content of iron tailings continues to increase, the mud content shows an increasing trend. When iron tailings and fly ash are both sieved to 150 mesh, there were more large particles of 150–200 mesh in iron tailings than fly ash.
2018-11-23 Mine tailings are, potentially, the most environmentally hazardous part of any mining operation. GEA has developed diverse technologies that can significantly reduce the impact of tailings on the environment and help minimize water usage, while isolating and extracting valuable minerals which can become an additional revenue source.

2010-12-15 Mine tailings are the ore waste of mines, and are typically a mud-like material. Worldwide, the storage and handling of tailings is a major environmental issue. Many tailings are toxic and must be kept perpetualy isolated from the environment. Scale of tailings production is immense, since metal extraction is usually only ounces or pounds, for
2021-8-20 For the dry treatment, no water (from the environment) is required to process the extracted ore; thus, there is no need to build tailings dams. In comparison to the wet processing, the dry processing technique reduces the total water consumption by 93%, on average.
