Salt is a rather vague term chemically, so a description of what you did or a photo of the salt will get you back on the road to recovery.

I picked this off of the cotton filter. This is my first time trying to refine gold. It’s such an interesting process learning

I’ll post another picture after it’s all filtered off so you can see

 

[Ahk]

Ok this is what I have in the bottom of my beaker

Mt first guess would be you didn't filter the solution effectively and what settled out after you dropped the gold was a mixture of Silver Chloride and Gold powder. If this is true, a soak in an ammonia solution will dissolve the Silver Chloride leaving clean gold.

The photo came in after I started typing and the chunks look like undissolved metabisulfite. If that is the case, hot water should dissolve it away.

Actually it may be a little bit of both.

Thank you so much, man I really appreciate the help. Is it possible to dissolve the silver into some nitric

silver metal dissolves in nitric, Silver Chloride does not, that requires ammonia or sodium thiosulfate.

Perfect thank you for helping a rookie out

Also wash that solid material many rinses to get rid of any undissolved stuff.

Is there a certain concentration or will regular store brand work just fine

 

[4metals]

Off the shelf drug store ammonia will work, it just may take a bit more. Warm it and do it in a hood as another term I always used for ammonia was genie in the bottle because of the white fume created when near aqua regia. Be sure to neutralize the solution when you are done. Use Hydrochloric Acid and if there is any silver in the solution it will turn the liquid white as the Silver Chloride forms.

If you have choices of ammonia jugs check percentages.

ok so quick update tried to dissolve the salt by heating water still wouldn’t dissolve. This is what is left I’m now about to heat ammonia to try and put the silver into solution

This looks like ordinary coarse sand.
What is your start product?

It really does it freaked me out I’ll go grab a pic of it, just a bunch of connectors and low grade pins

I think you have arrived at the point where a description of what you started with and what you did next as well as when you tested and how will get you to the bottom of this quickly. If you did the ammonia, did acidifying it with Hydrochloric Acid give you indication of Silver Chloride? Having us fill in the gaps about what you did by assumption is not as definitive as you telling us the story. Sorry, we tried the quick way, now let’s do it the proper way.

Roger that. I followed a trinity gold video I went directly to aqua regia as per instructions, let all metals dissolve I did that step 3x, until the reactions stopped
Then I strained it all out rinsed it all into my bucket, resulting in this
I tested for gold and stannous came back positive for gold, I then proceeded to denox with urea. I know for a fact I used wayyy to much SMB to drop, that my good sir is how I ended up in this pickle

Prior to urea sorry it’s out of order that was after the aqua regia
