  • Ore Sorting & Pre-Concentration
    Sorting Ore in The FlowsheetThe Economics of Ore Sorting & Pre-ConcentrationOre Sorting by Sink-Float For Pre-ConcentrationThe place at which ore sorting will be done is mainly dependent upon the size of the mine-run ore. If the ore is not in too big chunks, the sorting belt may be placed below the grizzly or trommel to receive the oversize after it has been sprayed with water. The grizzly undersize is transported direct to the storage bin. If mine-run ore is in too large pieces, it should be broken to 4- to 7-in. size, sprayed, and then fed to the sorting belt. The wash water containing the fine material sometim...
  • Sensor-based ore sorting to maximise profit in a gold

    The available sensor technologies for particle ore sorting are not able to directly detect gold occurring at the typical fine grain size of most deposits, be they refractory or free milling. Therefore, the sensors are used to detect minerals associated with gold or alternatively characteristics of gangue or waste material. For example, gold is
