Abstract

Device and process for separation of absorbent/floating material from product mixes by means of float/sink separation with a float/sink separator which exhibits a separator tank filled with a liquid separating medium, in which context there are provided devices for generation of a surface flow in the separating medium, which propel the absorbent/floating material as a floating fraction from a pickup point of the product mix to an output point for the floating fraction, along the surface of the separating medium, at such a speed as to inhibit absorption of the separating medium.
