The effective recovery of copper from waste slag is of paramount importance for both environmental and economic reasons. This abstract presents an overview of a study focused on the determination of main technological parameters required for restoring the quality of copper in waste slag. Waste slag, often generated as a byproduct of various metallurgical processes, contains valuable copper content that can be reclaimed using suitable techniques. The research discussed in this abstract encompasses the systematic investigation of critical parameters such as temperature, composition of fluxes, reaction time, and the choice of reducing agents in the slag treatment process. Various experimental methods, including thermogravimetric analysis (TGA), X-ray diffraction (XRD), and scanning electron microscopy (SEM), were employed to analyze the transformation of slag components and the behavior of copper during the restoration process. The results obtained from this study shed light on the optimal conditions for copper quality restoration, leading to improved metal purity and recovery rates. The identification of these key technological parameters not only enhances the efficiency of copper recovery but also contributes to reducing environmental impacts associated with slag disposal. Furthermore, this research underscores the potential for sustainable resource utilization, as the restored high-quality copper can be reintegrated into various industrial applications, thus minimizing the need for virgin metal production and reducing the carbon footprint. In conclusion, this abstract highlights the significance of determining and optimizing the main technological parameters for the restoration of copper quality in waste slag. Such research endeavors offer a promising avenue towards sustainable and efficient metallurgical practices, benefiting both the industry and the environment by reducing waste and conserving valuable resources.
