Možnosti úpravy a využití jemných odpadů z výroby štěrkopísků

Abstract

The bachelor´s thesis examines the formation, processing, and utilization of fine was-te generated during the production of sandy gravel. The theoretical part describes the charac-teristics of sandy gravel, methods of their extraction, and the formation of waste materials. In contrast, the practical part focuses on the experimental processing of samples from the Ha-lámky and Chlum nad Malší localities. These samples were treated with air classification and magnetic separation, then analyzed. The results show that an appropriate combination of these methods can produce usable products, such as quartz and feldspar fractions or concen-trates containing rare earth elements and ilmenite.
