Abstract: Disclosed, is a valve apparatus for use with flotation cells. The valve apparatus is characterized in that it comprises a nozzle tube (202) for attaching to the wall (110) adjacent the orifice (102). The nozzle tube (202) is provided between the orifice (102) and the dart (100) and configured such that while in use, the dart (100) does not come into direct contact with the orifice (102) provided to the wall (100). The nozzle tube (202) further comprises an inwardly-tapered inlet (204) which extends from a wider open end to a throat (206) of smaller diameter. By virtue of the shape of the upstream-facing surface (112) of the dart (100) and the inwardly-tapered inlet (204), a nozzle structure is formed as the dart (100) moves upstream or closer to the throat (206) of the nozzle tube (202). This nozzle structure is particularly adapted for reducing head losses.

Abstract: A system for the continuous monitoring of wear is disclosed. The system comprises a flotation cell [1] having at least one flotation component [2, 4, 5, 6, 7, 8, 13]. At least one detector [9] is provided to the at least one flotation component, and at least one sensor [10] is provided to the flotation cell [1] which is configured to communicate with the at least one detector [9] during operation of the flotation cell [1]. In use, the at least one flotation component wears away and ultimately affects a function of the least one detector [9]. The at least one sensor [10] is configured to monitor said function of the least one detector [9]. When the at least one sensor [10] detects a change in the signal of the at least one detector [9], an operator is notified that maintenance or flotation component replacement may be necessary.

Abstract: A filter cake analyser (1) is disclosed. The analyser (1) may include a probe (7) configured to extend into a path of filter cake (6) (or other material) and convey a sample amount of filter cake (6) from a catch basin (9) to a probe discharge (11). 5 A sample cup (17) of an indexable cup assembly (16) is filled with the sample amount of filter cake (6). A rotational actuator (22) supporting the cup assembly (16) indexes the cup assembly (16) between three cup assembly positions. A dryer (15) of the filter cake analyser (1) dries the contents of the sample cup (17), and a load cell (28) intermittently engages and disengages with the cup assembly (16) 0 via an actuator (26) to obtain dry and wet mass measurement values to calculate moisture content of the sample amount of filter cake (6).

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 separator device (100) includes a separation chamber (107) defined at its lower end by a fluidization fluid panel (111). The separation chamber (107) receives incoming slurry (113) via a slurry inlet (102). The separator device may be characterised in that means (122) for supplying pre-sheared aerated fluidization fluid is provided above the fluidization fluid panel (111). The means (122) for supplying pre-sheared aerated fluidization fluid includes a novel sparger (119) comprising a flexible perforated membrane which is configured to supplementally shear the pre-sheared aerated fluidization fluid and uniformly distribute microbubbles (129) throughout the separation chamber (107).

Abstract: A self-aspirated froth flotation cell 100 may include a slurry vortex stabilizer 166 having an annular body 234 with an upper annular edge 176 and an aperture 180 extending through a central region of the annular body 234. The aperture 180 may have an inner surface 182 bounded between an upper inner edge 178 and a lower inner edge 200 that is configured to allow the drive shaft 142 to rotate freely therein. The slurry vortex stabilizer 166 may have an annular undersurface 210 configured with a inner first portion 212, a second portion 236 provided around the first portion 212, and an annular intersection, transition, or inflection 214 therebetween. A sloped upper surface 242 which tapers downwardly towards the central region of the annular body 234 as it approaches the aperture 180 forms a lower fluid surface boundary within a standpipe 152.
