Flotation tailings from copper production are deposits of copper and other valuable metals, such as Mo, V and U. New hydrometallurgical technologies are more economical and open up new possibilities for metal recovery. This work presents results of the study on the extraction of copper by mixed extractant consisting p-toluidine dissolved in toluene. The possibility of simultaneous liquid ...

and Ore Processing Facilities Project (NorthMet) proposed by PolyMet Mining Corporation to extract copper, nickel, cobalt, and precious metals. The joint EIS will allow evaluation to the NorthMet project in accordance with the National Environmental Policy Act (NEPA; 42 U.S.C.
Ores that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.
New Tailings Reprocessing Technology Has Environmental Benefits ... Very small diamonds can be recovered from the residue of the original diamond-bearing ore, and the U.S. Geological Survey found that discarded mine tailings may yield significant amounts of rare earth elements. Several efforts are underway to extract gold and copper from 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. It expects to recover 58 kg of gold per month, and has enough slimes to last until 2025.
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 ...
With advent of novel technologies, mining companies are now figuring out ways to extract valuable metals from tailings. In gold, copper sulfide and iron ore tailings, the potential of extracting minerals is an opportunity. Reprocessing tailings to collect the valuable minerals can be a cost-effective approach compared to processing material.

The filtering and tailings cost of the operation works out to be approximately US$4 /t of ore processed. This is significantly higher than a comparably sized copper operation which uses a conventional tailings method, such as Lundin's Neves Corvo whose tailings cost is only US$1.80–1.85 /t processed.
The properties of copper tailings, a fine-grained residue waste produced from beneficiation of copper ore, and their effects on the properties of bituminous mix were studied by Oluwasola et al. (2014, 2015). The copper tailings were used at 20% content as a fine granite replacement for …
