DRD Gold extracted 33,600 ounces of gold, worth nearly US40 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.

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.

Tailings Disposal of Mining Metal Ores Industrial Minerals. Mining and oreprocessing methods are similar in the metalore and nonmetal mineral industries, as are waste disposal techniques. The wastes of interest are waste rock, overburden and oreprocessing wastes (or tailings).
historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term environmental liabilities associated with acid mine drainage. The tailings from the reprocessing plant will be re
Jun 29, 2018· Tailings from the ore processing facility will be treated to reduce the cyanide levels and stabilize mercury, and would then be transported in a pipeline to the Tailings Storage Facility (TSF) built in the Anaconda Creek valley. The TSF will be constructed by building a tailings dam across the lower part of the valley.
The slime residue from the absorption section can be pumped either to the tailings dam or the backfill plant. Finally, the gold bearing carbon is removed from the absorption section and pumped to the elution circuit to remove the gold from the carbon. The gold in solution is plated out in the electrowinning circuit, where it is smelted.
The gold ore is doublerefractory. First, the gold is locked in sulfide mineral particles that must be oxidized to expose the gold for leaching. Second, the ore also contains pregrobbing carbon that will collect solubilized gold from the subsequent leaching circuit if the gold is not first removed.
