Resource Technologies

Energy > Energy Efficiency, Materials and Resources - All Topics

From the copper cables to the lithium batteries, metal and mineral raw materials play a vital role in our everyday lives. The demand for these resources in terms of quantity and diversity is increasing, especially for use in renewable energy, electromobility, communications and other advanced technologies. At the same time, however, ensuring their continued availability poses a growing number of global challenges, as mineable deposits tend to be located in inhospitable areas or at great depths, while the ores themselves have low metal content and are often fine-grained and complex in structure. How can supplies be secured in the long term? An important contribution to the more efficient use of resources can be made by recycling (known as the Circular Economy) and by minimizing loss from the system. The Helmholtz Institute Freiberg for Resource Technology (HIF) is dedicated to providing the innovative technologies that are urgently needed.

HIF was set up in 2011 by the German government as part of its national strategy for raw materials. The research team has been drawn from multiple scientific disciplines and has been gathered together under a single roof to look into such issues as the exploration, processing, metallurgy and recycling of mineral resources. By precisely analyzing the properties of raw materials and the valuable substances they contain as well as by means of computer simulation, it is possible to quantify the material and energy efficiency of processes along the value chain and to identify new solutions for the socially responsible and commercially viable use of raw materials. The focus at HIF is on complex resources from primary and secondary sources as well as on high technology metals such as indium, gallium, germanium and rare earth elements.

HIF is a constituent part of the Helmholtz-Zentrum Dresden-Rossendorf and works in close collaboration with TU Bergakademie Freiberg. It is a core member of the European EIT RawMaterials network, having played a decisive role in its establishment.
