Research on Beneficiation and Reprocessing of Gold 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.

How to reshape the future of tailings?
Mining involves processing of mined ore to capture valuable minerals, which in turn produces large volumes of tailings. The annual global tailings production is currently estimated to be at the range of 10-12 billion tons/annum and increasing. Therefore, it's important to reshape tailings management and accelerate the positive change.
