what is sorting in mineral processing

  • Mineral processing metallurgy Britannica

    Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations

  • What is Ore Sorting? Ore Sorting Australia

    Simply put, ore sorting is the process of separating mineral particles into ‘the ones you want and ones you don’t’. The process of mineral sorting has been around for centuries. Traditionally precious stones, copper, iron, and other minerals have been sorted by hand.
