Screw up.

[dansdismantling]

Good afternoon members!! After more than two months off due to shingles on the face and in the eye I decided to try to work with the acids again and I had two different batches going both close to being done,so here’s what I screwed up I had one batch that I dropped the gold,mind you these were both dirty due to some oils I didn’t clean off of materials. So one dropped and the other was ready for AR I accidentally did the AR in the beaker I had just precipitated so now I have a combination of SMB with AR in it. Actually it was H202 34% and Hcl with now Smb. So the gold ore was re-dissolved. I was so irritated with myself I put everything away and went home. Just got back to the shop and the solution in the mishap beaker is full of slush???? I have water bottles that didn’t freeze and it’s like 40F here?? Did the smb mixed with H202 quagulate?? I’m stumped and disappointed I made this mistake. Now how to fix this,since it has Hcl smb and H202 34% steam it off and start over??? Any help would be greatly appreciated!!!!

I forgot to mention it is also saturated with silver chloride…..

Can you clarify.
AR or HCl/Peroxide?
Anyway anything with Chlorides will not dissolve Silver.
What was your material?

Hcl and high strength peroxide 34% dissolves gold no problem. The material is old pins in their sockets. Once the foils came off I removed the sockets. I dissolved the gold then precipitated the gold then accidentally dumped smb in it again. I got the two beakers mixed up.

That is not AR and it do not need denoxing.
Just keep it close to boiling and stir it for a while.
Then add SMB, or other precipitant of your choice.
If that do not work, use a piece of solid Copper to cement it out.
If you have added too much SMB add water and heat it while stirring until the extra SMB dissolves, then siphon off the liquid.

Any thing with Chloride will NOT dissolve Silver.

in your first post you say you did AR again in the precipitated beaker (decanted or added acids to the solution with SMB?)
and in your second post you said you added SMB to the precipitated gold.. which is it?

I forgot to mention it is also saturated with silver chloride…..

What is full of AgCl? The foils or the precipitated solution?
Any silver should have been filtered out before precipitating the gold.
so you got me confused.
