A method for extraction of noble metals from industrial waste comprises treatment of initial raw material by electrolyte containing trivalent iron in the lixiviation chamber and electrolysis in electrolysis chamber. The initial raw material is preliminarily annealed, lixiviation chamber and electrolysis chamber are filled with initial aqueous solution of electrolyte of specified composition. This invention relates to a method for extraction of noble metals from industrial waste and can be used in jewellery for reprocessing waste based on iron and chrome oxides.
