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.

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.
