The degradation of the hydrothermal base mineralisation (galena, sphalerite, pyrite, pyrrhotite and chalcopyrite) and of fine-grained pyrite oxidation, which forms impregnations in hydroquartzite produce AMD. The area is acidified and the country components (soil, rock, water) are contaminated mainly by Pb, Zn and Fe. The tailing pond dam forming soils show acid pH (2.28 – 3.25), whereas the soil on the tailing pond surface is close to neutral pH (7.26). The availability of the metals from the soil is up to 75 %. The AMD from the hydroquartzite quarry is in comparison with those percolating the tailing pond sediments very acid (pH 2.71) and contains high concentration of metals (Fe 311 mg.L-1, Zn 1690 µg.L-1, Cu 890 µg.L-1, Pb 126 µg.L-1).
