mine water discharged by Grootvlei Proprietary Mines in South Africa, RO was one of the technologies assessed (Schoeman and Steyn, 2001). • The TDS in the feed, 2000-4500 mg/L, was reduced to potable water standards at 85% water recovery. • The flowrate of the brine stream for an 80 ML/d plant at 85% recovery was estimated to be 12 ML/d.
Tailings, especially those obtained in the past, have remaining copper and other valuable species in quantities that can potentially be recovered, such as gold, silver, vanadium, and rare earth elements which transforms this abundant waste into a potential source of precious or strategic metals for secondary mining.
3.1 SETTING OF THE MINE SITE Tailings management is typically easier, at least physically, in dry climates, where advantage can be taken of desiccation (that is, drying by exposure to the wind and sun) to naturally dewater, increase the density of the tailings and strengthen the tailings. However, on desiccation in a dry climate, sulphidic

Sep 13, 2019· Say a copper mine produced 1Mt of metal in 1999 at 90% recovery. The remaining 10% of copper, around 111kt, went to tailings. If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal. Fast forward 20 years and at today's price, US$5,842/tonne, if that material could be reprocessed and an extra ...

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...
