AB  - To increase the degree of cobalt (Co) extraction, the process of the cathode material leaching was performed in a sulfuric acid (H2SO4) solution containing sulfur dioxide (SO2) as a reducing agent. To provide a high resolution of the obtained results, frequent monitoring of Co concentrations in leached solution was conducted using an ultraviolet–visible spectrophotometer with several specific modifications related to the connection of the reaction vessel with the instrumental cuvette. The maximum degree of Co leaching (99.4%) was achieved with H2SO4 concentration of 3 mol/L, solid phase concentration of 33 g/L, temperature of 85 °C, SO2 volume flow of 2 L/min, and leaching time of 60 min. The results of the performed kinetic analyses indicated that the Avrami equation best describes the investigated leaching process, which later was supported by the results of X-ray diffraction and scanning electron microscopy–energy-dispersive X-ray spectroscopy analyses. Also, the activation energy of 28 ± 3 kJ/mol is in favor of the fact that the process of Co leaching was controlled by the factors, such as diffusion and chemical reaction. The results of this study indicated that SO2 can be used as an effective reducing agent in the investigated process.

AB  - In the modern practice of copper production, more attention is increasingly being given to the possibility of treating low-percentage sulphide ores that cannot be treated with conventional procedures (crushing, grinding, flotation). In addition, the processes of obtaining copper from complex sulphide concentrates, which cannot undergo pyrometallurgical processing, are increasingly being investigated. In most cases, the extraction of copper from such raw materials is achieved by applying the leaching procedures. Since chalcopyrite (CuFeS2) is the most abundant copper sulphide mineral, a great part of the research is focused on studying the behaviour of chalcopyrite in the leaching process, because processes of copper extraction from increasingly poor raw materials may be created using results of these studies. In addition, the main goal of these researches is to investigate the kinetics and mechanism of oxidation of chalcopyrite under the influence of various oxidants (O-2, Fe3-, H2O2, chlorate ions, etc.) and in the same time obtaining data necessary for the development of copper production process that could satisfy increasingly technological, economic and environmental stringent criteria. This paper presents the existing knowledge of chalcopyrite leaching and phenomena that follow chalcopyrite oxidation in acidic sulphate and chloride solutions.
