INFACT’s first trials of innovative, non-invasive mineral exploration ­techno­logies are imminent

The EU-funded INFACT project, which is coordinated by Helmholtz Institute Freiberg for Resource Technology at Helmholtz-Zentrum Dresden-Rossendorf, aims at combining the development and test of innovative, non-invasive minerals exploration ­techno­logies with an assessment of their social acceptance. For this purpose, three European reference sites will be established in Germany, Finland and Spain. Stakehol­der consultations took place at all sites in June and early July to pave the way for first technology trials which are about to start in August.

Raw Material­s Deposits in the Erzgebirge: Researchers aim to extract metals from local complex ores

Freiberg is at the centre of efforts of European raw-materials experts who aim to show that important metals can be extracted commercially from complex, composite ores that previously could not be exploited economically. The consortia of the German national project AFK, coordinated by the Helmholtz Institute Freiberg for Resource Technology (HIF) at Helmholtz-Zentrum Dresden-Rossendorf, and the European funded project FAME, managed by Wardell Armstrong International UK (WAI) and Geokompetenz­zentrum Freiberg (GKZ), have joint forces to invigorate complex ore processing by using modern rock analysis methods and compu­ter simulations. The newly designed process is now to be tested in a pilot plant trial in Freiberg with 150 tonnes of ores from the Hämmerlein-Tellerhäuser deposit in the Erzgebirge.

Masters of the rocks: Professional networking for mineral sample pre­parators in Freiberg

Analysis technology has become so sophisticated that it now affords astonishingly accurate insights into the structure of rocks and minerals. But it is not only rock in its natural state that comes in for analysis but also specially prepared samples. There is a dedicated laboratory for this at the Helmholtz Institute Freiberg for Resource Technology (HIF), part of the Helmholtz-Zentrum Dresden-Rossendorf. From 13th to 14th March, mineral sample pre­parators from uni­versities and research institutes in Germany, Austria and Switzerland will be gathering together here.

Erzlabor: A spin-off for raw materials characterization

HZDR Press Release (Feb. 07, 2018): Profound understanding of raw materials’ characteristics is essential for process and resource efficiency in the mining as well as in the recycling sector. Material­s characterization has become a powerful tool for the acquisition of quantitative data and is already applied along the entire raw materials value chain, from the exploration of new deposits to their rehabilitation. The newly established company ERZLABOR Advanced Solutions GmbH provides analytical services for the primary as well as secondary resource industry. The team of scientists and engineers from the Helmholtz Institute Freiberg for Resource Technology (HIF) – part of HZDR – make state-of-the-art infrastructure and analytical competence available for the industry.

Back to the factory instead of in the garbage

Developments in waste ­manage­ment are supposed to head towards a circular economy: in accordance with this ideal, all the material used in manufacturing a product should be recyclable at the end of their lifespan. But a lot still has to happen before we get that far. As studies have shown, when it comes to electronic waste, modular construction and smart sorting would help to recycle valuable metals.

A foam bath for ores

In nature, raw materials do seldom occur in a pure form. The valuable particles in the ores first have to be painstakingly se­parated from other materials and enriched. The leading method for doing this is flotation. HZDR scientists examine its underlying mechanisms and microprocesses with the aim of optimizing industrial processes and improving the extraction efficiency in raw materials processing.

Germany’s hidden treasures

The Energiewende is systemically changing our use of raw materials. While the need for coal, oil and gas is decreasing in the long term, the demand for metals and construction materials for energy-efficient wind and solar plants, battery and hydrogen storage or other systems is growing. Germany is not yet fully exploiting its potential in this field.
