This study investigates the distribution of gold particles in technogenic placer deposits and the associated losses during extraction processes. Gold is predominantly present in fine, dispersed, and submicron forms, making complete recovery through conventional gravity separation methods difficult. Consequently, a considerable amount of gold is lost during processing. The findings indicate that the application of surfactants and sorbents can significantly enhance the recovery efficiency of fine gold particles. In addition, chemical and nanochemical approaches are identified as promising directions for improving overall gold extraction performance.
