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 rotor (1) for a self-aspirated flotation cell (100) includes a body (2) having a base (25), and a bottom surface (19) that may be frustoconical. The rotor (1) may have a plurality of vanes (8) extending radially-outwardly from the body (2). A pumping cavity (9) may be centrally disposed within the rotor (1). The pumping cavity (9) may be defined below the bottom surface (19) and between inner surface portions (22) of the plurality of vanes (8). The plurality of vanes (8) may each extend from an upper vane surface (10) to a lower vane surface (18). The lower vane surfaces (18) may extend beyond the bottom surface (19) of the base (25).

Abstract: A disperser hood (1) for a self-aspirated flotation cell (100) includes a collar (2), and a conical member (4) extending downwardly and radially-outwardly from the collar (2). The disperser hood (1) may be characterised in that it further comprises a plurality of vanes (6) extending downwardly from the conical member (4). Each of the plurality of vane (6) may have a lower side (8), a radially-inner side (9), and an external radius, curve, or chamfer (7) extending between the lower side (8) and radially-inner side (8).
