A tailings storage facility is a facility used to contain tailings. This can include a tailings dam (impoundment and pond), decant structures and spillways. A tailings storage facility can also be open pits, dry stacking, lakes or underground storages. A tailings dam is a tailings embankment or a tailings disposal dam. The term

The gold mine tailings used in this study contained As, Cr, Cu, Ni, Mn, Zn, V, Sb, Pb, Ba, and sulfate (Table 2). ... Cr was leached out from the reference sample indicating that some contamination from crushing and milling equipment occurred during CSAB clinker production. The leaching of Cr decreased when the amount of mine …
A previous feasibility study for the gold resource using conventional cyanidation showed net operating cashflow of A$30.6 million, net present value (at 8% discount) of …
At present, the common gold mine tailings treatment methods and comprehensive utilization mainly include the following ways. 1. Re-selection of gold mine tailings. The gold content in gold mine tailings is generally 0.2-0.6g/t. Due to the backward mining technology in the past, some of the gold and silver is lost in the tailings.
This paper describes the mineralogical properties of gold tailings, including chemical composition, phase composition, particle size distribution, and microstructure; …
Mining of minerals such as gold, copper, and platinum has been one of several activities sustaining the economy of South Africa. However, the mining sector has contributed significantly to environmental contamination through the improper disposal of mine tailings which covers vast areas of land. Therefore, this study utilised a vitrification process to …
From satellite networks to digital twins, we look at the latest digital tools for tailings monitoring. Scarlett Evans August 2, 2024. Both aerial and ground-based tools …
New technology allows it to recover up to 40% of the gold left in particle form in tailings. DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013. Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources.
Mine tailings are generally disposed of by artisanal and small scale gold miners in poorly constructed containment areas and this leads to environmental risk. Gold phytomining could be a possible …
Similarly, tailings dumps arising from the processing of chrome ore in the Lower Group reefs of the BC are also being retreated to recover PGEs. Several commercially profitable enterprises have also been set up with the sole intention of retreating tailings dumps arising from South Africa's Witwatersrand gold processing …
