Conceptual Design For Treatment Of Mining And Metallurgical Wastewaters Which Contains Arsenic And Antimony, Zeljko J. Kamberovic
Conceptual Design For Treatment Of Mining And Metallurgical Wastewaters Which Contains Arsenic And Antimony, Zeljko J. Kamberovic
Zeljko J Kamberovic
This paper presents a preliminary design for treatment of mining and metallurgical wastewaters (MMW) from the basin of antimony “Zajača“, which contains high concentrations of arsenic and antimony. MMW have been investigated in laboratory, due to large difference in concentrations of pollutants. Metallurgical wastewaters were treated using iron (II)-sulfate and lime milk used to adjust the pH value at 7. After chemical treatment of metallurgical wastewater and its joining with mining wastewater, residual amount of arsenic in water was below maximum allowed concentrations, while the concentration of antimony, remained above the maximum allowed value. The final phase of purification process …
Possibility Of Secondary Lead Slag Stabilization In Concrete With Presence Of Selected Additives, Zeljko J. Kamberovic
Possibility Of Secondary Lead Slag Stabilization In Concrete With Presence Of Selected Additives, Zeljko J. Kamberovic

A comparative technical and environmental evaluation of products arising from the stabilization/solidification of secondary lead metallurgical slag into a cement matrix was performed. Provided samples of an industrial slag generated in the process of recovery of lead from automotive batteries (Engitec CX process), were used in experimental work. Characterization of slag by X-ray Diffraction (XRD), Atomic Absorption Spectrometry (AAS) and Optical Microscopy (OM) revealed that slag contains a certain percentage of sodium and lead, in the form of oxides and sulphides, as well as unreacted coke and iron compounds. Dissolving of the slag components causes migration of ions into water …
Selective Removal Of Heavy Metals From Metal-Bearing Wastewater In A Cascade Line Reactor, Zeljko J. Kamberovic
Selective Removal Of Heavy Metals From Metal-Bearing Wastewater In A Cascade Line Reactor, Zeljko J. Kamberovic
Zeljko J Kamberovic
This paper is a part of the research work on 'Integrated treatment of industrial wastes towards prevention of regional water resources contamination – INTREAT' the project. It addresses the environmental pollution problems associated with solid and liquid waste/effluents produced by sulfide ore mining and metallurgical activities in the Copper Mining and Smelting Complex Bor (RTB-BOR), Serbia. However, since the minimum solubility for the different metals usually found in the polluted water occurs at different pH values and the hydroxide precipitates are amphoteric in nature, selective removal of mixed metals could be achieved as the multiple stage precipitation. For this reason, …
