Shower of pos­ter awards for HIF researchers

HIF staff members have lately been successful with presenting their research at various conferences. Dr Rohan Jain, a Marie Curie Fellow at HIF’s Biotechnology Group, has received a pos­ter award for pursuing an entirely novel approach in biotechnology in order to reco­ver gallium from wastewater. PhD student Bruno Michaux, who works with the Processing Division, has won a pos­ter award for introducing a modeling and simulation approach to handle water chemistry issues in ore processing using flotation. And his colleague Haosheng Wu was just given a best student presentation award for her research dedicated to the microanalysis of raw materials (see news of 20 Sept).

Microanalysis of raw materials: Best student pos­ter award

Haosheng Wu, a PhD student at Helmholtz Institute Freiberg for Resource Technology (HIF), won a best student presentation award at the 21st International Conference on Secondary Ion Mass Spectrometry (SIMS). Part of HIF’s Processing Division, she applies methods of the institute’s Ion Beam Analysis Group, thus linking both teams closely. The conference took place from 10 to 15 September 2017 in Krakow, Poland, gathering representatives from both academia and industry to exchange results and new ideas on SIMS and related techniques.

A different approach to networking – First-e­ver HIF science slam

Around 120 researchers, technicians and administrative staff are currently employed at HIF, which operates three different sites in Freiberg and Dresden. As a mat­ter of fact, hardly any team member will know all the others. But how can the networking and scientific exchange be facilitated? In order to achieve this, HIF’s first-e­ver science slam took place on 1 September.

A mobile extraction plant for recycling of copper and indium

There is as yet no commercially viable method of salvaging all valuable metals from the dust generated during the production of copper and zinc. The HIF is conducting research into a new process specifically targeted at recycling the rare metal indium.

Electronics recycling and its environmental footprint: The “Fairphone” example

In Germany, less than half of electronics waste is recollected again. Meagre collection quotas are just one, albeit ­very important reason why there is still so much left to do when it comes to recycling. The complex design of modern electronical devices like in a mobile phone is by itself a great challenge for reco­vering valuable metalliferous and mineral resources.

Explore, analyze and process raw materials

Freiberg’s terra mineralia exhibition is offering a new series of summer workshops for anyone interested in exploring, analyzing raw materials and enriching minerals; the series is being conducted in cooperation with the Helmholtz Institute Freiberg for Resource Technology (HIF), part of the Helmholtz-Zentrum Dresden-Rossendorf, and other partners. All raw materials enthusiasts aged 12 and o­ver are welcome to take part. The first workshop takes place on Wednesday 28th June 2017.

EU supports innovation and sustainable mineral exploration

The Helmholtz Institute Freiberg for Resource Technology (HIF), which is part of the Helmholtz-Zentrum Dresden-Rossendorf, will receive a grant of approximately €900,000 o­ver the next three years to support the development of new ­techno­logies for the environmentally and socially sustainable as well as efficient exploration of natural resources. The EU funding will be made available by EIT RawMaterials, which is supported by the European Insitute of Innovation and Technology, and has already been earmarked for three new projects. The researchers are seeking to advance drone-based exploration and other innovative exploration methods.

The addition of chemicals makes the ore particles differentially wettable; valuable substances are extracted while worthless particles are left behind. The valuable substances are attached to air bubbles, transported upwards and can thus be separated. ©Copyright: HZDR/ 3D Kosmos

Copper mining with bioactive substances derived from bacteria

Chile is one of the most important suppliers of copper to German industry. Within the framework of the scientific and technological cooperation between the two countries, research is now being pursued into how Chilean copper ores can be extracted in a more environmentally sustainable way. Bioactive substances derived from bacteria may replace or reduce chemicals. A further aim is to increase metal yield while extracting metals that are traditionally difficult to se­parate out, in particular the molybdenum content. The joint project between Helmholtz Institute Freiberg for Resource Technology (HIF) – part of HZDR – and the Advanced Mining and Technology Cen­ter at the Uni­versidad de Chile in Santiago de Chile began in February.

Future raw materials experts from all o­ver the world attend win­ter school in Freiberg

The youngs­ters attending the Win­ter Business School (9th - 27th January 2017) come from Brazil, Colombia, China and India as well as many other parts of the world and have already graduated in subjects such as Geology, Mineral Engineering, Physics and Chemistry. They are united by a desire to identify solutions to the challenges faced by the raw materials industry and to obtain a European Master’s in Georesources Engineering. This includes a three-week win­ter school in Freiberg, Saxony. 18 students from the course are taking part.

Raw material exploration 2.0

There are many known ore deposits on Greenland, but also many sites that are difficult to reach. An innovative ‘toolbox’ based on drone-borne methods as well as specialised compu­ter software could soon make the exploration of raw materials significantly easier. Researchers from Freiberg are hereby collaborating with the Geological Research Institute of Denmark and Greenland (GEUS).
