FIELD: metallurgy.
SUBSTANCE: proposed method includes reduction of silver chloride at heating and holding at heat in flow of gaseous hydrogen, bubbling of gas escaping from reaction chamber through water and obtaining aqueous solution HCl. Reduction is performed from silver chloride formed at refining of noble metals and ground to size of ≤100 mcm and located in reaction chamber at thickness of layer of ≤20 mm at temperature of 450°C±5°C by gaseous hydrogen heated to holding temperature.
EFFECT: increased degree of extraction of silver from silver chlorides.
