The impact of the tailing dam of the SASA mine on soils in the Kocani valley

Flotation tailing dams affect the environment through the soil, water and air, and in that way they affect the plants and the animals as well as the people. This paper shows the quality of the soil according to the concentration of heavy metals in the surroundings of Sasa mine, more precisely, the Kocani valley which uses water from the dam Kalimanci. The dam receives water from the tailing dam of the Sasa mine. The results indicate the occurrence of two geochemical associations: association As, Cd, Cu, Mn, Pb, Zn, which is directly related to anthropogenic impact that comes with problems associated with the exploitation of Pb-Zn polymetallic ore, which are exploited in the area of Sasa - Makedonska Kamenica and in the region of Zletovo, and association and Ni, Co, Cr, which is basically defined by the lithology or present geological formations in this area. From the examination of soils taken from the Kocani valley, it can be concluded that the increased concentration of heavy metals in the western parts of the investigated area, near the Zletovica, is not a consequence from the water from Lake Kalimanci but it is the result of the influence thru “Zletovo“ lead and zinc mine have on the surface and underground water system Zletovica. It can be concluded that the water of Lake Kalimanci are still not contaminated to the extent that may endanger the soil system in the region of Kocani valley
