A method for treating a fluid slurry with concrete grindings to separate constituents thereof, the constituents including water, sand and cement particles, the method including removing solids (e.g. large concrete fragments, rock, etc.) from fluid slurry with vibratory separation apparatus, the vibratory separation apparatus having screen apparatus for separating materials, the vibratory separation apparatus producing wet solids flowing off the top of the screen apparatus and a fluid stream containing water and cement particles, the fluid stream discharged beneath the screen apparatus, feeding at least a portion of the fluid stream to centrifuge apparatus, and separating cement particles from the fluid stream with the centrifuge apparatus and producing a stream of water with the centrifuge apparatus; and re-usable cement particles recovered using such a method.
