Abstract

The invention relates to a method for preparing a suspension from a separation process  wherein the suspension is made of a particulate abrasive and a liquid slurrying agent. The method comprises the steps: a) thinning the suspension in a tank (1) with an additional slurrying agent (PEG) without adding additional water  producing a constant volume ratio between the particulate abrasive and the liquid slurrying agent; b) separating the thinned suspension into a liquid and a solid fraction in a centrifugal separator (2)  and c) subsequent refinement or reuse of the separated liquid and solid fractions.
