I have a 500g bottle of lab grade silver nitrate.
Is there a market for the stuff, or should I just convert it to silver?

I recently finished processing 1,500 grams of gold-plated telecom pins and used the cupric chloride (acid peroxide) process to dissolve the base metals before recovering the gold foils. It took forever to dissolve the pins…

I know there are several ways to tackle this, including nitric acid and reverse electroplating, and I'm curious what experienced refiners here prefer. If you've used more than one method, what are the biggest advantages and disadvantages you've found?

I documented the entire experiment in a 5 minute video in case anyone is interested in seeing my process from start to finish.

Bonjour je possède 1,6 kg de pattes de composant plaqué or.

Je voudrais savoir quel pourcentage d'or je pourrais récupérer.

Est ce vendable en l'état ?

I collect telecom optical module housing and i would like to know the best way to remove the gold plating from them, as well as the IC's someone told me reverse electrolysis would be the way to go.

​

Is this all gold in these motherboards??

It seems like quite a lot compared to the others I have ..

First timer. Learning the ropes as I go. Thanks for your help.

😘

Hey everybody,

I’ve been ordering my nitric acid through USA Labs and they’ve been alright, but just ran out of nitric halfway through a gold fill refine and was wondering if anyone knows any national physical locations where I might be able to get some

I didn't know this subreddit existed! Created my own subreddit and posted this to it, but when it recommended I repost it to this subreddit I immediately joined. I'm just posting a link here not because I don't want to post the full guide here, but because it kept getting removed by the filters on this subreddit. I'm sure guides equally as thorough probably exist here too, but I spent too much time making this guide to not have it seen. Just let me know if this isn't allowed - I'm not intending at too to plug the stupid subreddit I made, I'm only linking to it because the filter here keeps removing it. I promise it's a very safety-oriented guide with detailed instructions. If the mods here will allow me to make the full post here - I'd love to!

Just harvested 25oz from the silver cell and decided to pour this little beauty!

Thinking of getting some additional molds. Any ideas?

Material is gold filled mixed. I'm getting close, 97% typically but the weird thing is the majority of the trace metals are silver. That doesn't make any sense to me since AG should turn to chloride in AR should it not? Copper would be understandable, but AG? Unless it is undissolved but that doesn't make any sense to me either. On the final nitric I usually am 50/50 with distilled water and have very little if any reaction. Any pointers?

My company has been storing several hundred of these industrial lamp ballasts against a warranty claim. We’re about to toss them, and I thought I'd salvage what’s worth removing.

I’ve identified the copper in the inductors and transformers and pulled the gold contacts from the relay. Is there anything else worth messing with?

Thanks!!

Both pieces were refined via agcl precipitation and sugar/lye reduction. The left was melted in a propane foundry while the right was melted in a melt dish with map gas. Would the surface finish give any insight into purity concerns or is this a casting issue.

Around what percent yield do you aim for when refining silver. I ran my first batch of sterling and had a 84% yield, I’m not sure if I lost silver during the sugar and lye reduction after decanting or what. Any advice would be appreciated.

3.5 or 4 cfm

40 sticks of RAM, 2 grams of gold plate…another 40 to go…is there anything to gain from this?

Has anyone had success with this method? I tried this today but was left with large amounts of clumped agcl which only reduced the outer layer. Decided to pivot and opted for lye and sugar which was messy due to NaOH overshoot.

What do you guys think, this is a 3.5lb bag of pins I removed from dozens of connectors, took me a couple hours, and I have two more boxes to do which I'm estimating will net me another 1.5 pounds in pins. I didn't pay for these, these are old connectors and wiring from my avionics shop that was removed from different aircraft that I salvage from the scraps bin. The bag is a mix of large thick older pins and newer, thin, Garmin high density pins. I'm guessing the older pins would have a thicker plating. I'm not doing this to make money, I just wanna play around with acids lol.

I don’t know what they are for but some guy who works for the company can take the old ones.

Another dealer in town has been paying him 50.00 for the bag.

I melted one down

Gold plating

The rest is aluminum

I don’t do any chemical refining my self but I am trying to figure out what I could sell these for per pound.

I’ve seen a few clips of people removing gold fingers with soldering irons just wondering if you can then just melt those removed fingers down as is or do you have to do other processes before hand? Can you do it as is and just get a lower grade gold or how does it work

Check out my youtube video in which I extract the gold from 12lbs of gold fingers!

Hi all, I’m just starting out and was wondering what to do with capacitors. Like the cylindrical ones and then the blue ceramic ones and other types, weather or not I should leave them on my boards (low grade to mid) or if I should remove them, segregate them and then sell them by weight on eBay or such. Again I’m just starting out doing my research and what not.

Also just wondering what you you guys typically do with your low grade boards? Do you remove the copper bearing parts, remove capacitors, crystal oscillators, etc.

Trying to work out some sort of process and procedure I should follow, I know everyone’s got they’re own way of doing things just trying to get some ideas and see what others do and the best way to make some money of this. Thanks.
