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 within the Materials and Technologies for the Energy Transition 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.

Optimized buoyancy for ores: Innovative workflow optimizes reagents and increases the mineral concentration in the flotation process
Flotation is one of the most important processes for separating minerals in the raw materials industry. Achieving the highest possible mineral enrichment requires the appropriate selection and dosage of reagents - a complex, time-consuming and cost-intensive procedure. Researchers at the Helmholtz Institute Freiberg for Resource Technology (HIF), which is part of the Helmholtz-Zentrum Dresden-Rossendorf, have developed a workflow for the economic and ecological optimization and upscaling of flotation reagents. Initial tests on an industrial scale have shown a significant increase in the concentration of valuable minerals and confirmed the effectiveness of the developed approach.

The raw material detectives
In the European DeepBEAT project, scientists at the Helmholtz Institute Freiberg for Resource Technology (HIF), an institute of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), are pursuing the approach of using geochemical analyses to detect deep-seated ore deposits in a non-invasive manner. The researchers are testing the methods in three areas in Germany, the Czech Republic and Finland. The integrative involvement of all participants is an essential part of the project in order to improve mutual understanding in exploration projects. The EU is funding the three-year project with five million euros.
