Re-Processing Gold Tailings in South Africa

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 re-processing plant will be re-deposited in a new area far from urbanization, allowing ...

From Tailings to Treasure? Miners Make Money

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.

New Tailings Reprocessing Technology Has

However, some mining companies are figuring out ways to turn tailings to profits with novel reprocessing technologies to extract valuable metals from the waste. 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.
