Sažetak

Used auto catalytic converters contain PGM metals. There are many methods of recovering these metals from used auto catalytic converters, e.g. Rose method, cyanide extraction, chlorination, segregation, melting methods, blowing with metal vapours and metal collector method. They are based on pyro- and hydrometallurgical processes. As a result of such treatment the solution or metal collector with PGM metals is obtained. Then the important task is to separate the particular precious metals. In the paper review of such methods and short characteristics are presented. To those methods belong: classical precipitation method, solvent extraction method, solid–phase extraction method, chromatographic separation.
