Current Projects

VEGA 1/0313/20 – a member of the research team (2020-2023, principal investigator P. Koděra) „Genesis of precious metal epithermal and porphyry mineralisations in the stratovolcanoes Štiavnica and Javorie“ Click for project annotation

The project deals with the conditions of origin and genesis of two most important types of precious metal mineralisation in Slovakia that have a real economic importance. Completion of their current level of knowledge in terms of genesis can significantly help in exploration and mining of these ores. The epithermal vein Au-Ag deposit Banská Hodruša at the Rozália mine is the only mined ore deposit in Slovakia. The completion of genesis of precious metal epithermal mineralisation in the broad vicinity of this mine is necessary for its future effective exploration. Porphyry gold mineralisation, including the Biely Vrch deposit, is an unusual type of deposit, where gold was introduced by salt melts. Completion of its genetic model has a potential to significantly improve the knowledge of these rare magmatic-hydrothermal systems even in a global aspect, because due to their rare appearance the knowledge is still just on a low level.

APVV-20-0175 – a member of the research team (2021-2025, principal investigator P. Uhlík) „Bentonite: Slovak strategic raw material – Innovative assessment of bentonite quality and origin for its efficient use ”  Click for project annotation

Bentonite is an important industrial raw material. Due to the high amount of clay minerals from the smectite group, bentonite has unique properties, e.g. high swelling capacity, plasticity, high specific surface area, cation exchange capacity and low hydraulic conductivity. Due to these properties bentonites have broad range of possible applications. As a consequence, worldwide bentonite production is constantly increasing. Slovak republic (SR) is one of the world’s leading bentonite producers and bentonites belong to the strategic raw materials in SR. In the last 10-15 years, several new bentonite deposits have been opened in SR, most of which have never been studied in detail. This may mean that the potential of Slovak bentonites is not fully utilized. One of the objectives of the project is therefore the comprehensive characterization of bentonites from new deposits. The mineral and chemical composition of bentonites, their physico-chemical, mechanical and rheological properties will be determined. The obtained results will help to better understand the geology and genesis of bentonite deposits which may lead to the discovery of other economic accumulations of bentonites. The main contribution of the project lies in the rational and efficient use of domestic raw materials which will lead to the long-term sustainability of bentonite exploitation in SR. The idea itself is not new, but the way on how we want to implement the proposed changes is highly innovative. The main application outputs of the project such as: passports for the optimal utilization of different qualitative types of bentonites, 3D model of bentonite quality and geological model of selected bentonite deposit, will contribute to achieve this ambitious goal. The multidisciplinary team of experts on domestic and world bentonites in cooperation with major bentonite producer in SR, REGOS, s.r.o. is guarantee of successful solution of the proposed project. The partners of the project are the Earth Science Institute of the Slovak Academy of Sciences (SAS), the Institute of Inorganic Chemistry SAS and the Faculty of Civil Engineering, Slovak University of Technology in Bratislava.
