摘要:
Process for the selective separation, and for the simultaneous increase in purity, of two spent, fragmented, synthetic organic materials having different densities, mixed together or mixed with various contaminating materials to be eliminated, by means of dense aqueous media, each aqueous medium of which has a chosen density “ds” as threshold for separating said organic materials and contaminants, characterized in that the process comprises: a) a step of separating the mixture into two streams, a supernatant stream (a1) and a settled stream (a2); b) a step of separating the components of the supernatant stream (a1), by eliminating the supernatant fraction and collecting the settled fraction formed from the fragments of the first recyclable spent synthetic organic material; c) a step of separating the components of the settled stream (a2) by collecting the supernatant fraction and eliminating the settled fraction; and d) a step of separating the components of the supernatant stream by eliminating the supernatant fraction and collecting the settled fraction formed from the fragments of the second recyclable spent synthetic organic material.
