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 cast gold ingot at 95% plus purity is used as the anode.
May 14, 2015· The best way to extract the gold from scrap electronics for newbies is with a solution of hydrochloric acid (toilet bowl cleaner) and hydrogen peroxide and a fish tank air pump. After all pcbs are clean of any metals, melt all materials with copper to make a bar. Then after you can use electrolytic.

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 ...
