Abstract
This article provides an overview of methods for processing electronic waste (mobile phones, smartphones, printed circuit boards). The possibility of extracting tin from the waste of printed circuit boards of mobile phones using hydrochloric acid is shown. Established that the deposition of tin from the productive solution occurs due to cementation - an electrochemical displacement reaction between a cementing metal (aluminum) and a cemented ion (tin). The possibility of intensification of the process using a vibrating installation is evaluated. An environmentally friendly and efficient method for processing tin-containing electronic waste is proposed.
