Summary
The subject is focused on group of noble metals, their properties and structure of consumption as future sources for recycling. It familiarises students with selected secondary raw materials, with contents of noble metals, their material characteristics and possibilities of noble metals recycling. It deals with recycling at use of conventional pyro-processes and to the most widespread recycling processes of materials containing gold, silver, platinum, palladium and rhodium.
