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 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.
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.
In the mining process, ore mills generate huge amounts of waste, called tailings. These are most commonly dumped into ponds created from naturally existing valleys, and secured by dams. Other naturally sourced water, such as rainfall or snowmelt that was also collected in the ponds, needs to undergo the same treatment as the tailings.
