Apparatus and method for the beneficiation of ore and coal with the aid of ultrasound

摘要

An apparatus for treating a slurry with ultrasound to improve separation based upon specific gravity comprises a plurality of modular conduit units having substantially vertical walls defining a flow space through which a slurry may be pumped. Each modular conduit unit has mounted thereon ultrasound transducers for transmitting ultrasound energy into the slurry being pumped through the modular conduit unit and means for exciting the ultrasound transducers in a frequency range of 60 to 100 kHz.
