pH value and concentrations of total dry residue and suspended matter in the wastewater of the Majdanpek Copper mine

Abstract

pH VALUE AND CONCENTRATIONS OF TOTAL DRY RESIDUE AND SUSPENDED MATTER IN THE WASTEWATER OF THE MAJDANPEK COPPER MINE

Assessment of Water Quality of the Pek River Based on Physicochemical Analysis

“…Šerbula et al (2014; 2015) compared chemical analyses of wastewater in Majdanpek copper mine and influence of wastewater to the water quality of Veliki Pek river for the period from 2008 to 2012. They concluded that in earlier years impact was greater and that in recent years situation is better because copper mine Majdanpek worked hard to improve the quality of wastewater, and thus to reduce pollution [3,4]. In order to avoid large losses of copper through wastewater, Šerbula et al (2015) proposed to complement the existing wastewater treatment.…”

“…On that way copper would be transformed into copper sulfate and could be used in the Electrolytic Refining Plant in RTB Bor, thereby copper recovery would be complete. Also Šerbula et al (2014) proposed that for reduction of the concentration of suspended solids in wastewater of the filtration plant could be used coagulants aluminum sulfate, aluminum chloride and sodium aluminate in the sedimentation tanks for gravitational purification before discharging wastewater to the Veliki Pek river [3,4].…”

“…According to Šerbula et al (2015; 2014) in wastewater of the Majdanpek Copper Mine filtration plant (after treatment of wastewater of filtration plant in sedimentation tanks) it was found an increased content of heavy metal ions (Cu, Fe, Mn, Zn, Pb, Cd etc.) [3] and suspended particles [4] that exceed the values of the maximum permissible concentration defined by the relevant Regulation of the Republic of Serbia. This paper is derived from the results of activities of the project "Joint efforts for the protection and management of the Pek River".…”

Assessment of the impact of copper mining and related industrial activities on aquatic macroinvertebrate communities of the Pek River (Serbia)

“…The Institute for Public Health "Timok" is occasionally engaged by the MCM to monitor the quality of waste effluent from the MCM, as well as the water quality of the Veliki Pek, upstream and downstream from the mine's drainpipes. However, at the time this research was conducted, the effluent had not been treated in an adequate way [17,18]. Polluters such as CPF and the "Kaona" stone pit also have a strong influence on the Pek River, and these three sources' combined discharge released notable amounts of suspended solids into the river.…”

“…Better treatment of the wastewaters from the filtration complex of the MCM that carry most of sediment, could help to improve the ecological status of the water and biodiversity. Several technical solutions for upgrading the wastewater system were proposed in Šerbula et al [18].…”
