FIELD: production of metals of platinum group by extraction. SUBSTANCE: method of re-extraction of ruthenium from tri-n-butyl phosphate includes extraction and re- extraction. Extract containing ruthenium, copper and nickel is washed by hydrochloric acid solution for removal of copper and nickel from it. Ruthenium is re-extracted by acoustic soda solution. EFFECT: simplified procedure of purification of ruthenium re-extract from admixtures in refining. 1 tbl
