This article reviews recent literature related to electronic waste (E-waste) processing. The extraction of precious metals is shown as the main economic driver of E‑waste processing. The study methodology is based on collecting and analyzing statistical data and performing comparative analytical methods. The theoretical aspect is based on a critical analysis of the research of Russian and international authors. This article highlights the current pyro-, hydro-, and biometallurgical processing methods used for extraction of precious metals from E‑waste. A comparative analysis of known technologies for E‑waste processing is performed; their advantages and disadvantages are shown to achieve a cleaner waste disposal process. The technological and environmental aspects of E‑waste processing, as well as the effect of toxic substances and harmful components in E‑waste processing, have been subjected to a detailed analysis. According to the analysis results, existing technologies must be revised for a comprehensive solution to environmental problems. The increasing E‑waste formation demonstrates the necessity of new approaches and the development of innovative technologies for E‑waste processing. The use of E‑waste as an additional source of raw materials to produce precious and other valuable metals seems very promising.
