  • 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

  • Converting Tailings Dumps into Mineral Resources |

    Similarly, tailings dumps arising from the processing of chrome ore in the Lower Group reefs of the BC are also being retreated to recover PGEs. Several commercially profitable enterprises have also been set up with the sole intention of retreating tailings dumps arising from South Africa’s Witwatersrand gold processing operations. According to Munyar Chirisa, a chemical engineer and senior

    1. A gold processing plant in Inner Mongolia has a history of nearly forty years, which is a classical old processing plant. Before the new tailings pond construction completed in 2002, there are 90000 tons of tailings with recoverable tailing with high gold content in the old tailings pond. The gold content is about 1665 kg, and the silver

  • Passive treatment for the removal of residual cyanide in

    In the gold mining industry, tailings from the cyanide leaching process contain variable quantities of a number of cyanide compounds; as tailings are transferred to a pond for sedimentation and consolidation of the solid fraction, the supernatant water contains residual cyanide. A natural degradation of cyanide in tailings ponds is reported in the specialised bibliography, but in most cases

  • Tailingsfo What Are Tailings? Their nature and

    Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. This process of product extraction is never 100% efficient, nor is it possible to reclaim all reusable and expended processing reagents and

  • Sulphide Gold Ore Treatment by Leaching and Flotation

    Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an
