Abstract: 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).

Abstract: A feedwell assembly for a thickener/clarifier including a feedwell body, at least one feed channel connected at a downstream end to the body, and a plate member disposed in the feed channel for separating froth from an incoming slurry stream to where the separated froth may be dissipated by a liquid spray directed onto the plate member. The plate member may include a planar upstream portion inclined upwardly from an upstream end of the plate member and may further include a planar downstream portion inclined downwardly from a downstream end of the upstream portion. At least one spray nozzle may be disposed above an elevated portion of the plate member so as to direct a liquid spray onto the plate member in a region about the joint, for further dissipating froth guided onto the plate member.
