small scale ion exchange gold recovery

  • Process to electrowin gold from acid mine water?

    There are ion exchange resins that are selective for gold and platinum group metals recovery from acidic waters. Typically, these are not regenerated. Instead, they are sent to a refiner where the resin is burned, followed by metal recovery from the ashes. If you have soluble gold, then only good pre …

    Ion exchange can potentially treat poorly clarified liquors or even pulps, thus eliminating costly solid/liquid separations. The best-known metallurgical application of ion exchange is in the recovery of uranium -a process developed in South Africa in which Mintek, with its patented NIMCIX contactor, played a major role.
