Abstract: An assembly separates a multi-phase mixture into liquid (54) and dry (52) phases and employs a decanting centrifuge (100) with an annular immersion disc (14). A liquor weir is located on the end-face of the centrifuge drum (20). An Independent claim is also included for a separation process in which after starting the centrifuge drum (20) and setting an initial tank depth, the mixture (50) is introduced into the drum. The liquid and dry phases are drawn off. The tank depth and centrifuge fluid level are regulated by the liquor weir until a pre-determined dry substance concentration is reached. The tank depth is continually compared with a tolerance range. During the process the weir is so positioned that a reaction to feed concentration changes is possible in both directions. As the process progresses, the centrifuge speed is lowered in steps and the weir position adjusted so that the dry phase remains constant.

Abstract: Dependent on the quantity of froth produced in a flotation plant, process parameters which indirectly or directly affect the quantity of froth produced are reduced in their quantity depending on the quantity of froth produced. This is effected by reducing certain material flows, including those material flows which are circulated in a flotation plant. Fabrication waters used for dilution are partially replaced by fresh water. This prevents difficulties being caused in the operation of a flotation plant by an unduly large quantity of froth produced.
