FIELD: mining.
SUBSTANCE: invention refers to the area of the extraction of gold, palladium and platinum from hydrochloric solutions. The method comprises their anionite sorption and desorption. The sorption shall be performed with low-basic anionites. After sorption, desorption with a mixture of sodium sulfite salts mixture Na2SO3 and sodium nitrite NaNo2.
EFFECT: quantitative extraction of complex chlorides of gold, palladium and platinum from aqueous solution in a wide range of hydrogen chloride concentrations.
