  • Mineral processing - Concentration Britannica

    Mineral processing - Mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic ...

  • Ore sorting - Preceding processing Ausenco.

    4/3/2019  When positioned correctly in a process flowsheet, a pre-concentration stage or sensor-based ore sorting mechanism can reduce material transport costs, meaning less waste is conveyed or hauled to the next part of the mining process.

  • Mineral processing - Wikipedia

    Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.
