Evaluation of exploiting barite, the critical raw material in Slovakia, and benefits of its mining
(Dnipro University of Technology, 2021-06-30)
Purpose. There are several deposits of critical raw materials in the Slovak Republic, but currently only one is mined. This is
a barite deposit in Spiš, which shows an ever-lower volume of exploited raw material year-on-year. ...
Impact of Artana mine on heavy metal pollution of the Marec river in Kosovo
(Dnipro University of Technology, 2021-06-30)
Purpose. This paper aims to reflect the extent of the impact of the Artana mine on heavy metal pollution of the waters of the
Marec river. Mineralogical pollution of this river resulted in almost total degradation of ...
