Dilute nitric or nitrous acid solution containing halide ions as effective media for pure gold dissolution

The greatly enhanced oxidation ability of dilute aqueous nitric acid (0.10-2.0 mol L −1 ) containing bromide and iodide salts as well as chloride salts has been examined based on the dissolution kinetics of pure gold at 30-60 °C. It has been found that bromide salts are more effective than chloride...
