Opis:: The article presents current methods used for the recovery of metals from used electronic equipment. The analysis of the composition and structure of the material was made on the example of one of the most popular and widespread e-waste - used cell phones. The article was address the problems of processing and separation of individual components included in these heterogeneous wastes. The main purpose of the conducted research was to prepare the tested material in such a way that the recovery of metalsin the further stages of its processing was as effective as possible. The results of attempts to separate individual material fractions with magnetic, pyrometallurgical or hydrometallurgical methods will be presented. An analysis of the possibilities of managing electronic waste in terms of the circular economy will be made.

Opis:: The continuous changing technologies of electronic devices, mainly mobile phones cause that their life is shorten from year to year (even to 8-12 months); that is way there is a constantly increasing amount of generated waste. Such waste treatment to recover mainly copper and other base metals should be really profitable. The process of metals recovery could be done using different methods including pyro- and hydrometallurgical process. The paper describes the research of leaching process of Printed Circuit Boards (PCB) coming from waste mobile phones. As a leaching agent sulfuric acid was used with addition of hydrogen peroxides. Experiments were carried out for different temperature, acid concentration and addition of hydrogen peroxide. As a result the concentration of copper, zinc, iron and aluminium in the obtained solution was measured. The results were discussed.
