ABSTRACT:
A process for reclaiming composite materials that includes viscous and non-viscous constituents is described. The process comprises the steps of submerging the materials in a bath of liquid having a specific gravity greater than the viscous constituent but less than the non-viscous constituent, blasting the submerged materials with a gas or vapor heated to a temperature in excess of the melting temperature of the viscous constituent whereupon the viscous constituent is liberated from the non-viscous constituent and rises to the surface of the bath, skimming the viscous constituent from the surface of the bath, and emerging the non-viscous constituent from the bath.
