Processing raw materials - Fraunhofer IBP

Processing technologies are required both in mining in order to extract raw materials and in recycling to recover secondary raw materials. In addition to the conventional methods of crushing or grinding for breaking up materials mechanically, techniques used to process composites should ideally not only break up the materials but also separate them at the same time.
