Čištění důlní vody z antimonitového ložiska Poproč (JV Slovensko)

Abstract

The main objective of this thesis was to treat the problem of retrieval contamination of mine water (MW), especially in terms of the content of toxic pollutants such as antimony (Sb ) and arsenic (As). The first theoretical part of bachelor thesis describes the basic genetic classification of mine water, MW position within the Mining Act, but also the methods used in the treatment of mine water. The theoretical part also describes the basic properties of Sb and As as the main contaminants in the tested mine water and geological and hydrogeological conditions at the Poproč locality (eastern Slovakia), where MW samples were taken. The practical part of the thesis was focused on laboratory testing the effectiveness of selected remediation methods for the elimination of antimony from mine water collected on antimony deposit Poproč. Namely, under the column experiments, the Sb adsorption on activated carbon, Sb elimination using separate the strongly acidic cation exchanger Amberlite 120 operating in the Na+ cycle and elimination of Sb using a combination of strongly acidic cation and a weakly basic anion exchanger Purolite A-100 were tested. As last iron sorbent GEH was tested. In the process of elimination of antimony from mine water, combination of catex and annex and the use of sorbent GEH showed high efficiency (in both cases the efficiency of Sb elimination was 98 %).
