Abstract
Abstract Processes and apparatus for treatment of flowing slurries of particulate material mixed in liquid employ a wide, elongated downwardly-slanted, metal tray with upturned edge flanges, cable-suspended for unrestrained vibratory flexing and undulation. The tray is provided with a plurality of ultrasonic transducers mounted on its underside, and the flowing slurry is delivered to the upper tray end, flowing lengthwise down the tray in a shallow flowing sheet. Ultrasonic vibratory energy coupled through the tray to the flowing slurry has a "microscopic scrubbing" action on all particles and agglomerates, breaking the surface tension on the particle, cleaning particle surfaces, and separating different constituent particles and coatings of gels, slimes, algae, clay or mud. Mixtures of fine particles of coal or other valuable minerals with ash, clay, rock or sand particles are separated with unexpected efficiency by these techniques. In a second embodiment, a second reflection tray is provided superimposed on the first tray.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
122 words
The process of treating with vibratory energy a flowable slurry of particulate materials mixed in a liquid comprising the steps of providing a first laterally extended downwardly elongated treatment zone bounded by an adjoining flat boundary surface and a laterally extended downwardly elongated reflection surface located over the treatment zone, coupling vibratory energy through said boundary surface to cause the slurry to vibrate in a direction substantially perpendicular to its length and to its width at a frequency between about 10 kHz and about 50 kHz, while the slurry flows downward through the downwardly elongated treatment zone toward a lower exit end thereof, and thereafter conducting the treated slurry to a separation zone where the particulate materials are separated from the liquid.
Claim 2
Dependent Claim
122 words
The process of treating with vibratory energy a flowable slurry of particulate materials mixed in a liquid comprising the steps of providing a first laterally extended downwardly elongated treatment zone bounded by an adjoining flat boundary surface and a laterally extended downwardly elongated reflection surface located over the treatment zone, coupling vibratory energy through said boundary surface to cause the slurry to vibrate in a direction substantially perpendicular to its length and to its width at a frequency between about 10 kHz and about 50 kHz, while the slurry flows downward through the downwardly elongated treatment zone toward a lower exit end thereof, and thereafter conducting the treated slurry to a separation zone where the particulate materials are separated from the liquid.
Claim 3
Dependent Claim
30 words
