Abstract

See full text

Systems and methods are provided for processing abrasive slurry used in cutting operations. The slurry is mixed with a first solvent in a tank. The slurry is vibrated and/or ultrasonically agitated such that abrasive grain contained in the slurry separates from the other components of the slurry and the first solvent. After the abrasive grain has settled to a bottom portion of the container, the other components of the slurry and the first solvent are removed from the tank. The abrasive grain may then be washed with a second solvent. The abrasive grain is then heated and is suitable for reuse in an abrasive slurry.
