METHOD FOR SELECTIVELY SEPARATING USED COMMINUTE ORGANIC MATERIALS BY MEANS OF DENSE AQUEOUS SUSPENSIONS

摘要

The invention relates to a method for selectively separating synthetic organic materials such as polymers and/or reinforced or non-reinforced copolymers in the form of wastes, in particular domestic wastes recyclable in order to be reused. Said synthetic organic materials are recuperated from broken used cars and obsolete consumer durable products. The inventive method for selective separation consists in separating materials which have an identical density threshold value and are selected from a dense medium comprising separate liquid fluid suspensions which consist of powdery disperses particles in an aqueous phase and are stabilised with respect to the density threshold value selected in such a way that a selective separation of a determined fraction of the mixture of separable used material is initiated.
