The recycling of WC composite materials offers a wide range of advantages in ecological, economic and strategic fields. Since Austria covers the entire product life cycle along the tungsten supply chain, the source material for tungsten carbides (WC), from mining and production to recycling, this topic is of particular importance to the domestic economy. In general, it can be distinguished between direct, semi direct and indirect recovery routes, which are partly implemented and used industrially. Nevertheless these methods still require a significant extent of research and development regarding for instance introduced impurities or novel binder systems. Therefore, the CD Laboratory for Extractive Metallurgy of Technological Metals intensively examines these topics. Fundamental studies concerning the individual process steps create a detailed understanding of the respective operations and contribute to the improvement of the WC composite recycling. This counteracts future supply shortfalls and constitutes furthermore the basis for an increase of resource efficiency of the critical raw material tungsten.
