profitability of processing mine tailings

From Tailings to Treasure? Miners Make

2015-5-7  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

The Tailings Center - Mining Engineering

2021-2-26  Mine wastes include tailings and waste rock. Mine tailings are the waste solid residuum after separation of valuable minerals from economically worthless minerals (gangue). After extraction and beneficiation, the residuals from mineral recovery are normally discharged as a hydraulic fill (aka slurry) composed of finely ground gangue (sub ...

Report says mineral processing 4.0 is next step change ...

"Vale will rely on dry processing for 70% of its production by 2023, compared with 40% in 2014 and 60% in 2018," RFC Ambrian says. "Metso, a leading industrial company, suggests that only some 5% of tailings generated [globally] in 2018 were dewatered into thickened paste, or dry tailings, but expects that to increase to some 13% by 2025."

Innovative Project Heap Leaches Tailings in Parral

2021-2-25  By doing this we obtain a lower processing operation cost. The Parral project has a 60 percent value in silver and a 40 percent value in gold. This makes it is primarily a silver project. The process begins when we employ contract trucking, pick up the tailings, drop them at our new site, then mix them with cement to make a paste.
