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.
