Can You Remove Gold Plating with Sodium Bisulfate?

in this video, I experiment with reverse electroplating to see if it can be done with sodium bisulfate, instead of the typical sulfuric acid. sulfuric acid can be difficult to get hold of in some countries, so I thought I would try a new method.

Fan of sulfuric acid stripping cell , but good to know as a back up

Basically every electrolyte can be used to dissolve the gold into solution. The difficulty is getting the gold from small parts that are not worth putting on a wire

I see some using saltwater. Haven't tried it yet but think I will when ready.

trashed old car batteries wink wink

Copper sulphate is another option for electrolyte. I'd imagine you'd get somewhat faster results

I might try that on them next 👍

Can this be used for Glass or porcelain plated objects?

[@3-2preciousmetalrecycling]

Probably not. It would be very difficult to maintain an electrical connection. A leaching solution would probably be better iodine can leach gold plating. 👍

@ thank you I’m very new to all of this but from my job I got a buuuunch of circuit boards and glassware aswell as porcelain and am trying to learn I would love any pointers you have for me because I have a decent amount and would like to do it right and not just destroy or waste it all

The first tip I will give is before jumping straight in, do some reading and research. Check out the gold refining forum on the Internet and just read some comments. There will be people on there who have made mistakes when starting out, and there's some good advice for the problems they came across

Once you have researched, do small test batches to get comfortable with the reactions.
