Beschreibung
Zusammenfassung:	FIELD: metallurgy. ^ SUBSTANCE: invention refers to hydro metallurgy, particularly to method of desorption of gold and antimony with saturated resin. The method of desorption of gold and antimony with saturated resin includes treatment of resin with sulphuric solution of thiocarbamide with transfer of gold and antimony into the solution. At that the treatment is performed by stages: during the first stage desorption of gold is carried out by means of treatment with sulphuric solution of thiocarbamide, containing not more, than 15 g/l of sulphuric acid. During the second stage desorption of antimony is performed with sulphuric solution of thiocarbamide, containing not more, than 15-30 g/l of sulphuric acid, further resin is treated with alkaline solution, containing 45 g/l of alkali. ^ EFFECT: production of qualitative marketable electrolyte with low contents of antimony. ^ 4 dwg, 1 tbl, 1 ex
