ABSTRACT:
Method for the extraction of the metallic phase from dispersed mixtures of light metals and nonmetallic components. The invention pertains to an advantageous method for the extraction of the metallic phase from a dispersed mixture comprised of at least one light metal and at least one nonmetallic phase and, if applicable, at least the partial separation of the nonmetallic phase. The temperature of the dispersed mixture is raised to a temperature in the region above the melting temperature of the metal or alloy; the heated mixture is then inserted into an apparatus, subjected to an acceleration, and disintegrated, with the metallic phase thereafter being coalesced, collected and allowed to proceed to solidification.
