@Sreetips My guess was you would recover 5 grams! I've done similar batches of gold-plated sterling silver jewelry. You can expect about 0.5-1.0% yields. Sometimes that plating is under the minimum 2.5 microns, and the yield is a bit less. Awesome recovery yield video! These videos are so great! Sincerely, TBBW

Do you think there would be any benefit to doing a nitric boil either instead of or in addition to the hydrochloric boil at the end to clean up the gold? Correct me if I'm wrong but nitric alone won't dissolve the gold, or it might take a negligible amount, but it seems to me that with the gold in that highly particulated state a quick nitric boil would pull out any base metals that you missed in the previous steps.

Sreetips, was a little worried when the aqua-regia turned green rather than yellow/orange, but it looks like the green stayed in solution after the sodium-metabisulfite, is that what you saw too ? if so all was good. but the green may have been a sign to use ferrous-sulfate rather than SMB (but not sure which is more selective). I did see your follow up video where this button was added to some other karat scrap and that didn't turn green so this must have been a good refining. thoughts ?

Nice video. Separating the gold plated jewelry according to the base metals is a wise 1st step. I am curious to know: 1. Is the electrolysis method easier and what's the bath solution made of for gold plated silver? 2. Also can gold plated silver jewelry be done with a 2-3% iodine tincture leaching method? 3. Can your method be done with sodium nitrate? What would the solution be made up of? Ex: 17% sulfuric acid, distilled water, sodium nitrate, urea. I ask because its hard for me to get nitric acid. I can only access sodium nitrate. Also do you know about the gold leaching solution made up of mostly vinegar, a little of an oxidiser, and a little of mild acid, created by the University of Winnipeg. I am guessing the oxidiser could be sodium nitrate, and the mild acid could be oxalic acid or citric acid. Whats your thought on this?
