• New approaches for extracting and recovering metals from

    most effective extraction of copper (84 to gt90%) was achieved by bioleaching the tailings at 45 176C, using a defined microbial consortium, where elemental sulfur was added to the tailings and the pH of leach liquors allowed to fall to pH 1, at which point anaerobic conditions were imposed.

  • 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. The extraction of minerals from ore can be done two ways placer mining, which uses water and gravity to

  • Vanadium Extraction Process Mineral Processing amp Metallurgy

    extraction and recovery process of vanadium as a byproduct from the tailings of a uranium processing plant poses many problems. In this study vanadium is recovered from impounded resininpulp tailings and from the current tailings of a uranium plant which did not include a circuit for vanadium recovery in its initial design.
