Investigation of Sterile Mining Dumps Resulting from Ore Exploitation and Processing in Maramures County, Romania

Abandoned sterile dumps can be a significant source of environmental pollution, therefore the distribution trace elements throughout mining is vital. Monitoring factors in closed perimeters aims to track quality discharged waters emissary and assess acid mine drainage, soil vegetation, stability, condition land surfaces within perimeter deposits. One primary sources land, water air pollution dumps. Knowing first step adequately managing affected areas. This paper investigates physical–chemical properties concentrations heavy metals resulting from mining. We studied one dump that was result ore processing whose surface covered with abandoned mixed concentrate (Pb, Zn), located Băiuț area (Romania), second exploration exploitation work Ilba (Romania). In order determine physicochemical characteristics concentration metals, 27 samples sample were taken dump. Additionally, 10 collected Aqua regia extractable determined by inductively coupled plasma optical emission spectrometry. At same time, using portable XRF, we analyzed selected each site for total metal concentrations. Furthermore, site, FT–IR The pH values both highly acidic (≤3.5) content generally increased.
