FIELD: metallurgy.
SUBSTANCE: invention relates to hydrometallurgy, particularly to a method for sorption extraction of selenium, tellurium and arsenic from solutions. Proposed method comprises adding soluble indium compounds to solution of extracted elements before sorption. Number of indium compounds must be greater than number of extracted elements in solution. At room temperature there is more rapid achievement of full extraction of said elements from solution. Use of indium in cationic form prevents undesirable reactions with formation of insoluble compounds.
EFFECT: technical result is use of indium salts for intensification of sorption of selenium, tellurium and arsenic on amino thioester sorbents.
