Sorry but in this process you dont extract gold, the only solution can dissolve gold is aqua regia nitric acid, and hydrogen peroxide. Separating Gold From Goldplated Gold Refining
#0183;#32;Gold, silver, platinum and palladium can all be recovered from circuits and processors of electronics. Of all the precious metals, gold is the one most frequently recovered and refined from electronics. Although it is possible to melt the gold plating away from the circuitry, you will cause more of a mess and lose some of the precious metal.
Two (2) major techniques for refining gold. Generally, gold can be refined using these twobestknown goldrefining procedures: Aqua Regia and gold electrolysis.

The removal of gold plating from jewelry is often desirable if the gold surface has become tarnished or lackluster. In most cases it will not be possible to preserve the gold as it is removed. Gold plating is very thin, usually over a silver or copper base, and the process will typically destroy the thin layer of gold
Sep 23, 2008#0183;#32;2003. A. I have a simplicity refiner from Shor at home and use it to refine karat gold. The alloy is dissolved into a saltwater solution by using either a rectifier or battery charger [affil. link to info/product on Amazon] (12 v 10 amp+) then the gold is precipitated by adding a powdered chemical (I believe is sodium metabisulfite). The quot;mudquot; is collected rinsed and dried and melted back to

The most you can get for gold is % that is for single refining and only if you spend a long time putting a lot of nitric acid, usually it''s between to %.
Gold fingers are typically found on PCI cards, ISA cards, or on Memory sims/dimms/etc. They create the corrosion free connection between the computer and the expansion card. This process can also be used to recover gold from CPU such as Pentium Pro, or Cyrix or older 486 and lower generation chips.
