News: Webinar: Mining tailings and metallurgical heaps in Europe
The RIS-RECOVER project team organizes a webinar series to disseminate the results of the project, together with results from other research projects around mining tailings and metallurgical heaps, with the first webinar focusing on an overview of mining tailings and metallurgical heaps in Europe.
Due to their quantity and composition, mining tailings and metallurgical heaps can pose a substantial risk to environment, while on the other hand representing valuable sources of secondary raw materials, including critical raw materials.
The RIS-RECOVER project aims for a zero-waste approach for mining tailings of polymetallic ores and heaps from the metallurgical industry in North Macedonia and as such represent a relatively undiscovered potential for the European raw materials market sector.
Agenda:
10:00-10:15: Trajče Stafilov and Robert Šajn, ENVIRONMENTAL IMPACT OF METAL PRODUCTION PROCESSES IN THE REPUBLIC OF NORTH MACEDONIA.
A detailed survey of pollution with heavy metals of soil, waters, sediments, air and food on the entire territory of North Macedonia have been carried out. Air pollution was investigated by the application of moss biomonitoring and dust samples. The obtained data are statistically processed and spatial distribution maps for each specific element are prepared to give a proper interpretation of the obtained results. Special attention was paid to the pollution with heavy metals in the regions with mining and metallurgical activities. It was found that the highest pollution is present in the areas with abounded or active mines and metallurgical plants. High contents of some heavy metals were also found in the areas were their contents usually vary gradually across the geochemical landscape and depend on the geochemistry of the underlying lithology.
10:15-10:30: Aleksandra Trenchovska, SAMPLING CAMPAIGN IN THE RIS-RECOVER PROJECT.
Within the framework of the RIS RECOVER project, the aim of which is to establish a roadmap for the zero-waste extraction of CRM and metals from mining tailings and metallurgical heaps in SEE, samples were taken from selected secondary deposits in North Macedonia. In our presentation we will introduce the sampling sites, the mechanical drilling equipment, the visual presentation of the drilling and the sample preparation.
10:30-10:45: Françoise Bodénan, REPROCESSING OF METALLIC MINING WASTE: CURRENT DRIVERS.
The presentation is about mining waste and the possibilities of reprocessing it, showing industrial experiences all over the world ; and research initiatives in Europe in connection with historical stocks and mining liabilities to be managed. Perspectives will discussed various current levers on the topic and opportunities for future research program.
The speakers
Prof. Stafilov graduated at the Institute of Chemistry, Faculty of Natural Sciences and Mathematics, Ss. Cyril and Methodius University, Skopje, R. N. Macedonia. He received his MSc in 1977 and PhD in 1985. From 1974 to 1978 he was with the Faculty of Natural Sciences and Mathematics, Skopje, as a teaching assistant, 1978-1985 he was with Ferronickel in Kavadarci as Laboratory manager. From 1985–1988 he was with Mining and Metallurgy Institute in Skopje, as scientific researcher. From 1985 to present he has been with the Faculty of Natural Sciences and Mathematics, Skopje, from 1997 as full professor. His scientific interest is related to analytical and environmental chemistry. He is an author of 25 books and of over 400 scientific published papers (over 220 published in journals with IF), over 600 presentation at the scientific conferences (45 as a plenary lecturer in 20 countries) and 8 patents. He is a member of the Editorial Boards of 10 international journals and of the Coordination Group Under the Global Monitoring Plan for POPs of the United Nations Environment. Prof. Stafilov has received many awards and recognitions, the most important of which are state awards “Goce Delchev” received in 2009 and 2017 for best scientific achievements in 2008 and 2016 in the Republic of Macedonia for the monographies “Geochemical Atlas of the Veles and its Environ” and “Geochemical Atlas of the Republic of Macedonia”, respectively.
Research assistant Aleksandra Trenchovska received the MSc in Geography from the University of Ljubljana, Slovenia. She is currently working on her PhD degree at the Department of Geography, University of Ljubljana in the field of geodiversity. As an assistant at the Slovenian Geological Survey she works on European projects in the field of mineral resources and geochemistry. Her scientific interest is physical geography and geodiversity. She has received several international scholarships and two awards for her master thesis.
Françoise Bodénan has a background (PhD) in chemistry, mineralogy and crystallography. She has been working at BRGM for more than 20 years. She performs research on the recycling of waste streams like incineration, fly ashes and mining waste, also coordinating project at national and European level. She is involved in post mining inventories with some expertise for the French Ministry, namely during a BREF document consolidation on the management of waste from extractive industries (BREF MWEI). BRGM is the French Geological Service with the main location in Orléans. With a staff of around 1000 people they are involved in geoscience topics.
