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.
Percolation bioleaching of copper and zinc and gold recovery from flotation tailings of the sulfide complex ores of the Ural region, Russia. The indigenous culture was grown in 250mL Erlenmeyer flasks containing acid mine drainage from the flotation tailings (10 mL) and 100 mL of sterile Silverman and Lundgren 9 K medium at pH 1.8.
The defined culture constructed from strains of acidophilic chemolithotrophic microorganisms exhibited higher rates of bioleaching than the indigenous culture obtained from the acid mine drainage. Treatment of the substrate with sulfuric acid (pH 1.24) resulted in recovery of 48.6% of zinc, 28.2% of copper, and 2.8% the total iron.
According to the company, the Las Lagunas project in the Dominican Republic involves reprocessing highgrade gold and silver refractory tailings that were accumulated at
High grade gold from mineralized samples taken at a couple gold mines on our mineral property and finding loads of vuggy quartz veins all over the claim. Our goal this trip was to mainly search
We have experience in Greenfield and Brownfield operations and frequently perform tradeoff studies to determine the best technical/economic solution for the mine, with particular emphasis on water recovery and life of mine planning.
