Abstract
Process for recycling and recovering metallic components of metal-matrix composites and purifying metal scrap comprises contacting the molten composite and metal scrap with a cutting elevation on the periphery of a rotating roller. The metallic components of the composite on cutting of the roller solidify without the non-metallic particles remaining in the melt and impurities, and leave the roller in the form of fibres or flakes. USE - Used in air and space travel, and also in the car industry. ADVANTAGE - The process is simple and efficient.
