Abstract[English]
A feedwell assembly (1) having a feedwell (3) and feed dilution apparatus (27) is characterised in that the feed dilution apparatus (27) includes a centrifugal impeller (16) arranged within a pump housing (9). The pump housing is arranged below a weir box (12) having an upper opening and a spill lip (12b). The spill lip (12b) is arranged at an upper periphery of the weir box (12). The spill lip (12b) is configured to be arranged below an air-liquid interface (20) during operation such that there is a depth of submergence (26) between the spill lip (12b) and the air-liquid interface (20).[French]
