The electrochemical dissolution of metals of the platinum group in acid solutions using an alternating current is investigated. It is shown that this is an efficient and promising method for the production of pure noble metal salts, and for the analysis and extraction of small amounts of noble metals from waste and poor ores, The production of pure bromides and chlorides of gold and rhodium is particularly! efficient because their rates of dissolution are high. The mechanism of the influence of the alternating current on the metal/electrolyte interface is also discussed.
