Key Enabler for a Sustainable Circular Economy of Minerals and Metals

The Helmholtz Institute Freiberg for Resource Technology (HIF) pursues the objective of developing innovative technologies for the economy so that mineral and metalliferous raw materials can be made available and used more efficiently and recycled in an environmentally friendly manner.

The institute is a constituent part of the Helmholtz-Zentrum Dresden-Rossendorf. It researches in the Resource Technology Topic within the Energy Efficiency, Materials, and Resources Program of the Helmholtz Association. HIF works in close collaboration with TU Bergakademie Freiberg and is a core member of the European EIT RawMaterials network, having played a decisive role in its establishment.

For sustainable raw material exploration: Freiberg-based start-up TheiaX enters market with innovative mapping methods

With the increasing demand for high-tech metals by the industry, mining faces complex challenges. The sustainable supply of raw materials requires energy-efficient and socially acceptable methods with low environmental impact. At the Helmholtz Institute Freiberg for Resource Technology (HIF) belonging to the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), researchers have developed novel, digital mapping methods for sustainable raw material exploration and extraction o­ver the past two years and brought them to market. The founding team of TheiaX is now offering these ­techno­logies to industry. The start-up is already the third spin-off of the Freiberg institute.

When batteries become foam: HZDR PhD student with concept for improved battery recycling at Falling Walls competition

Efficiently recycling batteries and reintegrating the reco­vered materials into production is still an apparently unsolvable problem for industry. That's why researchers around the world are looking for new approaches. One of them is Anna Vanderbruggen. The PhD student at the Helmholtz Institute for Resource Technology Freiberg (HIF) - an institution of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) - developed a concept to recycle graphite from used lithium-ion batteries. On November 7th, she will present her approach in the final of the future competition Falling Walls in Berlin.

The FineFuture project researches new ways to exploit the reco­very of fine particle fractions in metalliferous raw materials. Se­parating ­very fine particles is important for the valorization of multiple mineral resources, for example nickel, kaolin, feldspar, talc and magnesite. With a particular focus on froth flotation, the project aims at enabling the development of groundbreaking ­techno­logies in the raw materials sector.
