Abstract: At least one froth receiving device may be positioned in a slurry retained in a tank of a flotation cell of a flotation machine. Each of the froth receiving devices may be positioned adjacent to froth formed in the slurry by being positioned in the tank at a height that positions the froth receiving device in the froth or near the froth. Each froth receiving device may receive froth to extract the froth from the tank. In some embodiments, the extracted froth may be sent to at least one particle separation device so at least a portion of solid material in the froth is separated from liquid of the froth. The separated solid material may be moved to another machine for further processing for recovering the desirable material while any remaining solid material and liquid may be sent to another device for being utilized in further material processing.

Abstract: A flotation machine includes a stator positioned in a tank adjacent a rotor. The stator has a plurality of vanes. Each of the vanes has a plurality of slots formed therein. Each of the slots has a shape that is elongated in a direction along the width of the vane in which the slot is formed. Each of the vanes is spaced apart from the other vanes to which that vane is adjacent. The vanes are positioned in series adjacent a periphery of the stator to define a central opening within the stator that is sized such that the rotor of a flotation machine may be positioned therein. The stator may be retrofitted onto a prior flotation machine installation. For instance, a stator may be offered for sale and then installed onto a flotation machine. A previous stator may be removed before the installation of the new stator.

Abstract: An auxiliary stirrer tank for a solvent extraction system includes a tank that receives immiscible liquids for agitating together to facilitate mass transfer of a material and a shaft positioned within the tank that is rotatable within the tank via a drive mechanism. A first set of blades are attached to the shaft at a first location on the shaft. Blades of the first set of blades are spaced apart from one another about a diameter or periphery of the shaft at the first location and extend a first distance outwardly from the shaft. A second set of blades are attached to the shaft at a second location on the shaft. The blades of the second set of blades are spaced apart from one another about a diameter or periphery of the shaft at the second location and extend a second distance outwardly from the shaft.

Abstract: A flotation machine includes a stator positioned in a tank adjacent a rotor. The stator has a plurality of vanes. Each of the vanes is spaced apart from the other vanes to which that vane is adjacent. The vanes are positioned in series adjacent a periphery of the stator to define a central opening within the stator that is sized such that the rotor of a flotation machine may be positioned therein. An annular member is attached to each of the vanes of the stator and is positioned at a vertical location that corresponds with positions of the openings of the rotor to divert a flow of gas emitted via the openings of the rotor to facilitate bubble generation within the slurry.
