摘要： A flotation tank has an input to receive a slurry from a pipeline section. The slurry contains finer mineral particles and coarser mineral particles. The pipeline section has one or more loops or coiled sections arranged to perform partial centrifugal separation on the finer and coarser mineral particles. As the mineral particles are moved tangentially into the lower part of the flotation tank, the coarser mineral particles tend to be near the tank wall while the finer mineral particles tend to move into the central part of the tank. Air bubbles or lightweight synthetic bubbles are used to collect and lift the finer mineral particles to the upper part of the tank. The coarser mineral particles are recovered by using collection surfaces coated with a hydrophobic material.

摘要： An ultrasound device is provided for treating a pumpable or flowable medium. The device includes a treatment vessel which is comprised of a hollow longitudinal member having an entrance aperture and an exit aperture for transporting a pumpable or flowable medium there-through. At least three transducer attachment cavities are provided for in a sidewall of the hollow longitudinal member. The device further includes an acoustic transducer mounted in each of the cavities such that each of the acoustic transducers is operable to be driven at a frequency and an amplitude to impart energy into the pumpable or flowable medium and to produce cavitation within the pumpable or flowable medium in the treatment vessel. The transducer attachment cavities in the sidewall of the hollow longitudinal member and hence the respective transducers are distributed in a helical path around an axial length of the hollow longitudinal member.
