Abstract

The study of acid mine waters and drainage systems of certain poiymctallic and active mines in the Eastern Macedonia have shown that pH values are in the range 4.0 - 7.8 in the Bucim porphyry Cu-deposit, 4.8 - 5.1 in Pb-Zn mines Sasa and Toranica, and 3.4 - 5.1 in the Zletovo Pb-Zn mine. Both the underground and open pit mines drainage systems on a vertical scale are of several hundreds of meters (from surface to depth) and are affecting the adjacent waters with heavy metals. Determined metal concentrations in the polluted mine waters from the Pb-Zn mines in Macedonia were in the range: 10+1340 μg/1 Pb, 40 - 70070 μg/l Zn, 1 - 240 μg/l Cd. Also, increased concentrations were determined for Ag, Fe, Al, Ca, Bi, Sb etc. In the copper mine waters were determined heavily increased concentrations of 4 - 509838 μg/l Cu, 25 - 300 μg/1 Ag, 4 - 4890 μg/1 Co and increased concentrations of Fe, Ni, Cr, As, etc. In general, metal concentrations decreased downstream from the source due to dilution from other rivers and co-precipitation of metals on other mineral phases.
