Christian Doppler Laboratory for Extractive Metallurgy of Technological Metals

The Christian Doppler Laboratory for Extractive Metallurgy of Technological Metals under direction of Ass. Prof. Stefan Luidold, is established at the Chair of Nonferrous Metallurgy of the Montanuniversitaet Leoben and funded by the Federal Ministry of Science, Research and Economy.  In collaboration with industrial Enterprises it aims on the one hand at the development of applicable technologies and process routes for the reclamation of these elements from so-far unused particular sources (unconventional ores, residues, scraps, used consumer goods) and on the other hand at extension of the limited knowledge about their behaviour in diverse process steps. The latter constitutes an excellent base to broaden the range of economically and ecologically exploitable resources. Ultimately, this should encourage the position of the highly developed Austrian industry.

ACR - austrian cooperative research

We are a research network. Our institutes are committed to research and development for companies, especially for the benefit of SMEs.

ACR – Austrian Cooperative Research is a network of private research institutes offering applied R&D for companies. Our demand-oriented services are tailored to meet the needs of SMEs, in order to support their innovation efforts, to provide the necessary know-how and to strengthen their competitiveness.

In addition to R&D, ACR-institutes offer testing, inspection and certification as well as technology and knowledge transfer. They perform more than two-thirds of their services for SMEs. This is the reason why ACR has become the research and technology network with the highest benefit for SMEs in Austria.

That way, ACR helps that innovation is also present in SMEs and obstacles for accessing research and development are removed. At the same time, the ACR institutes are important interfaces between science and large enterprises (national and international) in the direction of SMEs.
