The Pollution of River Trepça with Heavy Metals as a Result of Exploitation and Processing of Pb-Zn Ore

Abstract

Intensive exploitation of Pb-Zn ore in “Trepça” mine during years 60-90, but since 2000 it has continued to cause serious problems of environmental pollution in general, but in particular on river Trepça, since this mine is located on one side of the banks of this river. After discharge process of untreated waters from mine galleries, the pollution with heavy metals of this river continues also during flotation process of Pb-Zn ore. Building object in one side of river Trepça, in which occurs the flotation process of this ore, located near the residence of the First Tunnel around 2 km below the Stari Terg mine. Our work based on laboratory analysis is focused on the degree of pollution with heavy metals of waters of the river Trepça, as a result of the impact of these two polluting sources.
