Your Gold Recovery Kit Includes... 500g bottle of Sodium Metabisulfite (NC-10319). 500g bottle of Urea (NC-2620). Sodium metabisulfite is commonly used to precipitate dissolved gold out of aqua regia and gold chloride solutions. When it is dissolved into water, sulfur dioxide gas is created which is excellent at precipitating gold from the solution.

Feb 11, 2012· Once you've reverse electro-plated you're left with a solution of gold dissolved in sulfuric acid. To extract the gold from the solution, you have to electroplate it onto a node. Then you can take the gold off that node and you should be left with an irregular chunk (or scrapings) or 24k gold.
Reverse Electroplating for Gold Recovery. Gold is typically thought of as a metal used for coins and jewelry. However, its resistance to corrosion, conductivity and malleability makes it useful for electronics. When electronics become defective, there are ways to recover the gold, such as reverse electroplating.
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. The most effective way to reclaim gold from scrap components is to use a process referred to as reverse electroplating.
The gold refining forum that I act as a moderator on [ed. note: goldrefiningforum.com] has done much work with the so-called "reverse electroplating" method of gold stripping using concentrated sulfuric acid as the electrolyte. It can be used to strip gold from most anything, including aluminum, without attacking the substrate metal (unless the ...
Electroplating changes the chemical, physical, and mechanical properties of the workpiece. An example of a chemical change is when nickel plating improves corrosion resistance. An example of a physical change is a change in the outward appearance.
Jun 06, 2010· The anodes for gold and platinum plating are typically platinized titanium, so that material can be used as the cathode in the setup you are describing -- but stainless steel is usually good enough, depending on the particular plating bath.
