  • Separating Minerals From Waste Mining Of Mineral

    A number of different separation techniques are used. These techniques are based on the properties of the minerals. Different minerals are often found together, for example copper and zinc, gold and silver or the PGMs. A combination of techniques are used to separate the minerals from the waste and then the minerals from each other.

  • Gangue Wikipedia

    OverviewRe-useSee also

    In mining, gangue is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped of valuable minerals; a worthless rock containing valuable material. The separation of mineral from gangue is known as mineral processing, mineral dressing, or ore dressi

    Separation in mineral processing refers to the separation between valuable minerals and gangue, and also the separation of valuable minerals themselves. Its aim to achieve a high quality concentrate product with maximum recovery. Separation in mineral processing is based on the physical and chemical properties of minerals and their relationship to the application of concentration technologies

  • Mineral sorting and quality control of rock LLA

    For a successful separation by RGB cameras, the colour of the valuable minerals and the waste rock fraction must differ significantly. If both fractions show a similar colour, the application of NIR-process technology will enable a successful separation nevertheless. Each NIR active mineral shows a unique pattern in the NIR spectrum.
