METHOD OF EXTRACTION OF NOBLE METALS FROM SOLUTIONS

摘要

FIELD: extraction of silver, gold, platinum and platinoids from solutions containing such elements. SUBSTANCE: method includes sorption with sorbent + hydrogen sulfide salt 1,3,6,8 tetra + azatricyclo (10,1,1) dodecane followed by separation of noble metals from sorbent-concentrate by ashing. EFFECT: increased selectivity of sorbent to noble metals; enhanced efficiency. 1 tbl, 7 ex
