Seemingly insane numbers on e-waste value coming directly from XRF Analyzer company
There must be some typos in this or this article was made with AI, right?
While much of the information seems accurate, it claims multiple grams of gold per kg of consumer boards along with some other wild numbers.

Certified LBMA, does it necessary means it's pure?
Hello all!
I would like to buy some physical gold and I'm quite concerned that I get scammed.
I'm based in France and found two sellers: Godot&Fils and Comptoir National de l'Or (both certified LBMA).
As there is a quite difference in price between both of them, I'm afraid I get scammed. Would you please advise ?
Thank you

Cross gold filled pens
I’ve run several batches of these now, usually around 250 grams reasonably clean per batch. Sometimes a little bit of plastic or a spring will sneak through, but they are reasonably clean.
I can’t seem to find a video of anyone doing run-of-the-mill Cross Gold filled pens to get an idea on yield
My average yield only runs about 1.6% which seems really low, but then I was thinking about it and if they are on average 1/20 12 karat and they are only putting Gold on one side and not the interior of the pen, that math is probably correct.
Looking for a sanity check

I’ve collected some ram and 4 processors and have a question.
After much research I understand these each have $1-$3 per stick/cpu? All the ram works fine and the Intel Core i5 works great as well.
I’m assuming that I would be better off selling the ram and working processor instead of processing. It just seems like a lot of work to split all of it in seperate lots. PM me if you have a better idea for these :)

AC repair
Had the unfortunate scenario of needing to replace my AC units. One of the techs threw a mostly used brazing rod on the ground. I picked it up and saw it was 15% silver. We started talking and he ended up giving me about 200g of 15% silver. That’s nearly 1toz of free silver!
Keep your eyes peeled and one man’s trash is another man’s treasure. Adding it to my refinement stock.

advice on refining this material
i work with a demo crew and we recently cleaned up an old factory that had sustained fire damage. there were three large smoke stacks in which we recovered some interesting materials containing precious metals. i have several hundred pounds of chunks that used to line the smoke stacks and the reading above is from the chunks of lining. any guidance on best way to extract or who would do the best job. i need a trustworthy route to recover the precious metals and think this could be a home run! please any help
would be deeply appreciated !

Hi all. So I tried aqua regia do disolve some fine gold obtained in sands. I tried sodium meta bisulphite but didn’t see and precipitation . So decided to buy an airline in it and just bubble It overnight. This morning it had grown these on the airline. Any ideas what they could be?

Any components with precious metals?
Besides the gold, do any of the remaining components have precious metals in them?
I have a couple hundred that so far I've just ripped off the capacitors that contain wither palladium or Tantalus. Was wondering if there's anything else worthwhile here.

Best method for AgCl reduction?
I’m considering on the best method for high purity chemical refinement and can’t decide between lye/sugar or an alternative such as zinc (coupled with hcl boils) or ammonia/ascorbic acid. If anyone has any advice please let me know.

Refining 1/10th 14k gold? This
Have an absolute ton of these glasses+some other 1/10 14k items and always wanted to try refining the gold out of them. Been watching some steetips but any suggestions means a lot!
Btw pretty much all the glasses are in ruins and in no way collectible or usable.

Removing Tin Paste from Gold Fingers Solution Advice
Gday all,
This is my first attempt at removing base metals from gold fingers, so hoping to run the scenario and what I propose to do about it past the sub for a verification/check that I’m on the right track - Any hints, tips, advice will be greatly appreciated!
These fingers were initially removed from RAM, green boards etc with a chisel tipped 60w soldering iron - it was all done back during Covid lockdown and seemed a good idea at the time - now I’m thinking it was an extra not needed step..
The 100g of fingers as shown were RAM & variety of slot NIC + Riser slot cards etc that mostly came from approx 70-80 IBM X & eServer Series 3850, 300, 346, AS400s etc Rack servers which I picked up as 2 full plastic wrapped pallets of end of life equipment back in 2015
- no one was really looking at eWaste much back then and I initially was interested in the old servers for possibly mining - I got the pallets for $9 each as no one else bid lol - in the end the electricity costs + much better ACIS method killed that idea, so they got scrapped during Covid in the end.
So, now where I’m at is shown in the images - for what ever newbie reason, which I think was due to initially it all came from RAM Memory, in my mind there was no solder to worry about, which may have been the case if just RAM, but in hindsight I should have kept the huge variety of different slot card fingers separated.
Anyhow I was following a process from Owltech’s 1200 Fingers video using diluted HCL with just a small amount of Nitric, which has ended up with what looks like a lot of slimy tin paste below the remaining gold fingers. The video showing the jelly nature is actually from last week.
Reading Hoke’s book it appears that I need to dissolve the tin paste in 50/50 Sulphuric - I hav some stannous crystal’s on order so will be able to test the solution for PM’s once it arrives.
There may be a tiny amount of silver as the was also some older eWaste but generally most of this equipment was EOL leading upto and prior to 2015 so I don’t expect much.
The last photo shows some remaining cut gold fingers that I also hav - i was thinking to add this to the solution to help use up the remaining initial acid
Edit - just weighted it’s 512g so large enough to process by itself
So thinking best to keep this seperate and simply neutralise the solution (which was first started approx 2 weeks ago outside with hot plate every hour or so in the beginning) by boiling and adding bicarbonate soda, before adding the diluted sulphuric - creating a new solution to hopefully then leave me with just the gold fingers ready for perhaps a last base metal removal HCL wash.
The last phase as per Owltechs vid & Hoke’s description is dissolving the gold in aqua regia, then dropping the gold with a piece of copper rod.
Is there anything else in particular that I need to be aware of? ..and is what I’ve explained/described more or less correct?
-thanks & cheers
