The high temperature and high-pressure desorption method is to install thegold-loaded carbonin a pressure vessel, and mix the solution with 0.4% to 1% NaOH and 0.1% NaCN, heat temperature to 130 to 160 ° C, under the pressure of 3.6 to 5.9 kg/cm2. Within 2 to 6 hours, thegoldand silver desorption rates ofgold-loadedcarbon exceeded 90%.

Gold electrolysiswas invented by Emil Wholwill in 1874. But various versions of this process have been developed over the years. It is an electrochemical process which has been applied in many large-scalegold-refiningestablishments or industries. The principle ofgold electrolysisis very straightforward or simple: Dore bar, which is a castgoldingot at 95% plus purity is used as the anode.

The method just described aims at leavinggoldin an insoluble state at the anode. Other impurities are usually left there, and thegoldsponge, or slimes, needs furtherrefiningby methods, to be indicated later. By using a suitable electrolyte thegoldcan be dissolved from the anode bars and deposited in sheet form on the cathode, while many metals can be left in solution. The active agent ...

The gold, which is not quite pure, is then purified by dissolving it in aqua regia and then selectively precipitating it. If the gold is greater than 25%, this will not work - the gold will form a crust on the surface and prevent the penetration of the nitric. Similar blockage would occur …
