The mining industry represented for numerous consecutive centuries an important branch of the Romanian economy. The specific activity of exploration and exploitation of mineral resources and ore processing in plants in order to obtain metals induced a further environmental pollution. The purpose of this paper is to identify pollutants in the mining perimeter Larga de Sus, Zlatna (Alba County) to determine the impact on environmental factors through geomorphological alteration of soil and continual pollution of surface waters.
