FIELD: chemistry.
SUBSTANCE: silver is extracted from the chloride solutions with bis (2,4,4-trimethylpentyl) dithiophosphinic acid disulfide at the concentration of 0.02-0.2 mol/l in diluent. Silver reextraction is carried out with solutions of thiourea.
EFFECT: increasing the efficiency of the silver extracting method by increasing the extraction of silver from chloride solutions and reducing the consumption of reagents.
