after the diamond ore is mined where is it processed in processing plants

  • Mineral processing

    This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue. The water extracted from the ore by dewatering is recirculated for plant operations after being sent to a water treatment plant.

  • Malachite

    Some definitions of minerals give them as inorganic materials, however both diamonds and graphite are considered minerals, and both are primarily comprised of carbon, which would make them organic. So this leads me, as an engineer, to believe that mineralogists do not have a good, precise definition of a mineral, but rather a loose definition.

  • How Are Diamonds Mined And Processed

    Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted. Depending on how rich the ore is, a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds. Even after extraction, the rough diamond is still far from being set in an engagement ring.

  • The Complete Story Of How Diamonds Are Mined

    Diamonds are also mined from the seabed using horizontal and vertical marine mining. The first step in processing diamonds is comminution i.e. breaking the ore by crushing and milling. After the diamonds are manufactured they are ready to be sold to jewelry makers and diamond wholesalers.

  • How is Opal Mined?

    If the boulders show any evidence of opalisation, they are first removed from the mined ground and collected for later inspection for opal content, and sorted in readiness for sale as rough, or for further processing. For boulder opal, some of the ironstone is left attached as a natural backing, producing natural doublets.
