HI, I'm new around. I'm trying to experiment just for fun, I forgot a lot from old chemistry lessons. My questions is: I have salty water which I perform electrolysis on using gold anode and copper cathode. From what I know when all sodium chloride has reduced i have gold chlorid and sodium hydroxide Are only these two substances created? Have all gold ions reacted with chlore?

Gold Electroplating is a method of depositing a thin layer of gold onto the surface of another metal. Gold plating finds its uses in jewelry, semiconductor industry. It often employed in electronics to provide a corrosion resistant surface. In this instructable, I am making alkaline gold plating solution which can deposit gold by electrolysis.

gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms ...

Gold mainly exits in the electrolyte, and little gold can be electrodeposited. Besides, the results of XRD and SEM show that the obtained metal powder is mainly copper and copper powder particles are mainly dendritic. On the basis of these results, slurry electrolysis could be applied to the recovery of copper and gold from electronic component.

Sep 12, 2008. #1. In the past I've used electrolysis to remove copper from (dore) bars placed in copper sulphate solution (12v across a bucket of the solution). I guess, I'm wondering how much the sulphate solution 'degrades' after time. In particular, while copper dendrites readily continue to form at the cathode, the solution changes color.

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.

The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride.

Electrolytic Methods Used in Refining Processes of Gold and Other Precious Metals. Electrolysis is an electro-chemical process where an electrical current stream is flowing between two electrodes and through an electrolyte.This process involves the transfer of metal ions through the ionised electrolyte solution, depositing positive ions on the cathode and negative ions on the anode.

Gold is soft so might be easy to erode or roughen and this would give it a dull non-reflective appearance. The fact that you seem able to reverse the degradation by remelting the surface would seem to support this scenario. I noticed this with my electrolysis experiments in junior high.

The gold anodes are made exclusively from the gold from the silver-cells, which assays about 875 thouhs gold, from 100 to 125 thouhs silver, and a small amount of base metals. This gives, in the first cells, cathodes about 998.7 fine, which, on being re-treated in the second set of cells, produce gold about 999.7 fine.

PREVENTING ELECTROLYSIS Electrolytic Corrosion (Electrolysis) occurs when dissimilar metals are in contact in the presence of an electrolyte, such as water (moisture) containing very small amounts of acid. The dissimilar metals set up a galvanic action which results in the deterioration of one of them. The following is a list of the more

The gold is separated from the solution by either running it over zinc shavings or by means of electrolysis. In either case the gold is deposited as a black mud and is periodically collected and refined. In electrolysis the solution flows continuously through vats containing either lead or tin plate cathodes and oxidized lead anodes.
