gold gravity separation tailing and middlings

  • Gravity separation ee Online Library

    Gravity separation is one of the oldest mineral processing techniques yet with modern developments it is still to the fore. Gravity concentration is essentially "a method of separating particles of minerals of different specific gravities by reason of their differences in movement in response to the joint simultaneous actions upon them of gravity and one or more other forces" (Taggart

    Some operators also have a tertiary bitumen recovery circuit where bitumen is recovered from the tailings (underflow) of the main gravity separation vessel. As in the case of middlings recovery bitumen is recovered using a series of flotation cells. This low quality froth is recycled back to the main gravity separation vessel for final clean up.
