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

Abstract

The paper analyses the average annual values of the concentration of total dry residue, pH value and suspended matter in the wastewater of the Majdanpek Copper Mine. It has been shown that certain results exceed the values of the maximum permissible concentration defined by the relevant regulations of the Republic of Serbia. The obtained results were compared with the permissible concentration limits prescribed by the Regulation of the World Health Organization and Directive 98/83/EC of the European Union as well as with some well-known examples in the world. The paper proposes an adjustment to the settling basin in order to reduce the loss of copper concentrate in the form of suspended particles in the wastewater of the filtration plant by using coagulants.
