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.
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
Mining-pedia is a valuable and professional communication platform who focuses on providing mineral processing knowledge, mineral extraction process and the concentration of ore.

pumping of the barren slurry (tailings) to the tailings storage facility. The processing plant has the capacity to treat up to 1.25 million tonnes of ore per annum. These stages can be described under three main headings: grinding and size classification to reduce the ore down to a fine particle size
The mine tailings were produced from grinding and metallurgical treatment of mineral from Eloy and Brunite mines between 1952 and 1981 . The main ore minerals are pyrite, sphalerite, galena, marcasite, and pyrrhotite. Other minor sulfides include arsenopyrite, minerals of the tetrahedrite-tennantite group, chalcopyrite, and stannite .
