With demand for raw materials higher than e­ver in Europe, so grew the discrepancies between the need for mining and the social reluctance. The INFACT Horizon 2020 project set out to unlock the unfavourable status of mineral extraction by developing more acceptable ­techno­logies to invigorate the exploration industry and map unrealised underground potential throughout Europe. INFACT documented their journey in a new video, showcasing these more effective, sustainable and acceptable practices.

Dr Wills recently held a guest lecture at HIF about "The Evolution of Mineral Processing". During his visit, he had the opportunity to look behind the scenes of the institute, but also enjoy Freiberg, Dresden and the mining museum in Altenberg. How impressed he was, can now be read in his MEI Blog.

The a majority of the Freiberg city council voted this week to sell 3.2 hectare to the State of Saxony to enable the expansion of the new HIF campus. Until 2030 up to 100 Mio Euros are planned to be invested into the area of the former research institute for processing (FIA) and to increase the number of employees from 140 to 350. Currently, the campus is undergoing constructions for the new metallurgy pilot plant. Another pilot plant as well as offices and labs will follow.

Recently, the European Training Network SULTAN has initiated its research on the reprocessing of tailings and the Helmholtz Institute Freiberg is part of it. To explain the research goals to a wide audience, the SULTAN team has just released its official video. In this animated video SULTAN Researcher Jillian Helser explains how the SULTAN target is to transform mining waste (tailings) into valuable products.

The Erzgebirge is set to become a model region for the forward-looking treatment of residual materials from the mining industry. Up to €15 million will be made available from the funding program WIR! – Wandel durch Innova­tionen in der Region (We: Innovation for change in the region) under the auspices of the project rECOmine – Ressourcenorien­tier­te Umwelt­techno­logien für das 21. Jahrhundert (rECOmine: Resource-oriented environmental ­techno­logies for the 21st century) set up by the German Federal Ministry of Education and Research. The aim is to promote new methods within the region and for the world market, by means of which tailings and metal-rich water from the mining industry can be sustainably reclaimed and the valuable residual materials can be economically extracted. The project is coordinated by the Helmholtz Institute Freiberg for Resource Technology (HIF) which is part of Helmholtz-Zentrum Dresden-Rossendorf. TU Bergakademie Freiberg and SAXONIA Standortentwick­lungs­- und ­verwal­tungs­gesell­schaft, a site development and ­manage­ment company, are involved in the running of the project, and it also enjoys the support of Wirt­schaftsförde­rung Erzgebirge GmbH.

HZDR Press Release of June 3, 2019: A foam bath for ores

Water is a vital resource on which many industries rely and which can be used more sparingly. An example is the beneficiation of mineral ores. Taking the raw material fluorite as their example, researchers at Helmholtz Institute Freiberg for Resource Technology (HIF) have now shown how water usage can be optimized. They have developed a new procedure that extends the simulation of the beneficiation process. It indicates the circumstances in which it makes sense for water to be recycled without incurring losses during ore enrichment. The consumption of fresh water can thereby be significantly reduced. This not only benefits the environment but also the mining companies, because it makes the extraction of raw materials more efficient. The researchers have presented their new procedure in the Journal of Environmental Management (DOI: 10.1016/j.jenvman.2018.11.139).
HIF is part of Helmholtz-Zentrum Dresden-Rossendorf and works in close collaboration with TU Bergakademie Freiberg.

HIF scientist Dr. Martin Rudolph was awarded the Science Communication Prize of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), to which the HIF belongs, for the successful and committed communication of the research topic "resource efficiency" to the general public and the scientific community. He heads the Department of Processing, which deals with the extraction of primary raw materials and secondary materials by flotation, the most common industrial process for the production of metal concentrates.

The German Resource Research Institute GERRI lately invited high-level representatives from politics, research and industry for a debate on Europe’s path towards a circular economy. During the roundtable organised by the network of resource research organisations in Germany, the experts looked at challenges but also discussed different solutions to establish a closed-loop life cycle for products in Europe.

During the last few years, the use of lead (Pb) in the EU economy has been called into question by some policy makers. Lead is frequently seen as a problematic metal that can be detrimental to human health; what is much less well known is its fundamental role in the Circular Economy. To provide a firm metallurgical background on the importance of lead, Prof. Bart Blanpain (KU Leuven), Prof. Markus Reu­ter (HZDR/TU Bergakademie Freiberg) and Dr. Annelies Malfliet (KU Leuven), active in the EU ETN SOCRATES network, have published a Policy Brief. They argue that restricting lead metallurgy in the EU would not only have a detrimental impact on the lead industry, but also on all the industries linked to it that work with elements like sil­ver, copper, antimony, tin, tellur and zinc.

Metal recycling is regarded as an important measure of the future to secure the supply of raw materials. Many experts agree on this. In most cases, howe­ver, it is unclear exactly how recyclable a product is and what proportion of the materials can be reco­vered at all. In an interview for the Helmholtz Association's "Earth and Environment" knowledge platform, HIF Director Professor Markus Reu­ter argues that the complexity of modern equipment and the resulting scrap make it har­der to close material flows and achieve a genuine circular economy.

Anyone working in a laboratory in research and industry also deals with chemicals and other hazardous substances. To avoid risky situations, employees receive regular training. The Helmholtz Institute Freiberg for Resource Technology, which is part of Helmholtz-Zentrum Dresden-Rossendorf, together with the laboratory equipment manufacturer VWR International, is organizing an in-house exhibition on the subject of work and environmental safety on Tuesday, 22.1.2019.
