Surface and underground waters pollutions in processing of Pb - Zn Miine 'Sasa' M.Kamenica, R.Macedonia

Natural waters (surface and underground) are the main source which provides the necessary quantity of drinking water as well as water for various industrial and agricultural needs. The discharge of the infected waters into the natural recipients can lead to environmental pollution and disrupt the ecological balance in the water ecosystem. The pollution as a consequence of the mining activities comprises the pollution of acid mining waters, hard metals, chemical reagents from the process of production, suspended materials and detached and overflow of waters in the hydro-refuse dumps. The most serious problem from an ecological aspect, connected to the flotation slag, is the discharge of the infected waters in the surface underground flow. The long-term discharge of the infected waters into the waters of the river Kamenicka, a great part of the vegetal and animal forms will be destroyed and their place will be replaced with those plants and animals that have a greater level of resistance. The figures presented in this paper are from the latest research concerning the presence of hard and toxic metals from the samples of the river Kamenicka
