    Abstract: The present invention provides a method of recycling a water-based wire saw cutting slurry waste fluid comprising abrasive particles and waste solids in a water-based carrier. The method comprises the steps of (a) separating the waste fluid into a first fraction and a second fraction, the first fraction comprising recovered abrasive particles, and the second fraction comprising waste solids and a portion of the water-based carrier; (b) optionally, separating the second fraction to separate the waste solids from the water-based carrier to form a waste solids portion and a recovered water-based carrier portion; (c) optionally, drying the first fraction from step (a) and separating the resulting dried abrasive particles from smaller waste particles to produce a purified recovered abrasive fraction; and (d) suspending particles of the first fraction from step (a), the purified recovered abrasive fraction from step (c), or both, in a suspending medium comprising at least a portion of the recovered water-based carrier from step (b), to generate a recycled water-based wire saw cutting slurry.
