Hi Mike, Awesome video! 1.2 grams is excellent! That's 6 grams per kilo. If Jani has 40 kilos of these pins - that's 240 grams of gold. Which is equal to about 7 3/4 ounces of gold. With todays gold price at about $2660.00 per ounce - Jani would have about $20,400.00 in gold! I'd say that's pretty damn good! Congrat's to Jani for all the hard work in collecting those pins. Thumbs up for a great video! Stay safe. Jim
I sure wouldn't mind having a few bins like that of my own. Can't imagine the time spent to pull all those. Takes me forever to fill my pint sized pickle jar. Welcome home.
Hoping you are okay and doing well after the hurricane man. He's front of your videos and was waiting for another one to make sure you're okay. Stay safe
I think it took longer than expected because telecom grade tends to have a pretty solid plating on it, so the AP couldn't get to the base metals on the inside all that easily, unless the plating was already nicked by handling. Same reason the initial bubbling was delayed because not much was exposed right away.
Reverse electrolysis is very messy and labor intensive. I like the 999 Dusan brute force method. He breaks all the "rules" and still gets good results.
I have always liked AP... It takes longer but it is more thorough.. looks like you might have left it for a little while longer to get rid of the rest of the bottom of the pins but it did a good job.... Would straight hydrochloric acid take the tin? What kind of time do you think that would take? I would think if the hydrochloric acid would just take the tin and lesser base metals... You could then move to AP for the copper... And then on to aqua regia.... Thoughts?
@@scrappydoo7887 After removing from the wire wrap pins from the board, there was some of the connectors left(plastic) I used two different methods for cleaning the pins, sulfuric and potassium nitrate, in several batches based on sorting. I had 3 separate batches. One batch didn’t dissolve at all with “poor man’s nitric”, probably the richest of the pin batches. I refresh the pins and rinse, and do final pin dissolve in nitric acid. This method is less than four hours. About the yield, these are very old high quality wire wrap boards, it took several 5 hour days to snip and prepare them for processing(recovery). There is no easy gold!
AP solution even with the 3% stuff does not need to be a 50/50 mix! That strong and it'll begin to eat into the gold somewhat. I mix mine fairly weakly and it does just fine.
Been waiting for a video from you for couple weeks… finally 🤓 I have me a nice little stack I need to process too myself. How the hell does dude get one of those switch towers like that
I have to add something on the HCl etching. What dissolves the copper is NOT the acid. What dissolves the copper is the CuCl2 - sometimes called Cu(II)Chloride. To get the reaction running you first need to MAKE some CuCl (does not dissolve) then oxidize it to CuCl2, which dissolves. This can THEN dissolve more Cu by CuCl2 + Cu => 2 CuCl. This THEN must be regenerated into CuCl2 to dissolves more copper. It is best to jumpstart the reaction by starting with CuCl2 from storage.
With all his gold to process I'm wondering if reverse electroplating would be a better option? Method 1. stainless steel pot with a cheapie 3v power supply. Neg terminal to the pot. Pos terminal to isolated SS knife. Salt water electrolyte. Dump all pins into pot. Turn on power. Gold will start to electropolish (de-plating) and go into solution. Stir often to make sure all pins come into contact with the SS pot. Water will turn muddy brown. Turn off power and decant solution into another container and look at the pins to see if all the gold has come off. If not, then just add fresh water and salt and do again. If yes, then add HCL to eat up the base metals and what you have left is the gold alloy to process. Method 2. Instead of adding all the pins in at once, use a copper or SS scoop and do a scoop full at a time. Both methods are easy, but I found method 1 to be the fastest. Cheers
@@Alex-kp3hr I used to be a fan of eco goldex. With cheap nitric and alternatives, it doesn’t make sense for high quality pins. Low quality insitu is another thing altogether, I use it on gold electroplated watches. I use the electrowinn method after, essentially the same as the deplating rig
If you use coffee filters for foils most rinse out into beaker easily. No need to use ashless lab filters, just toss those with other old gold filters. And cottonballs with foils is annoying in my opinion. 😂 Better for finely divided material.
With the reported yield, 40kg should be right around 240 grams of gold, or US$19,300 @2500 US$/g. If his other pins share the same yield its a very respectable 15.43 TOz of gold in total
I believe you are correct, but as more copper goes into solution the dissolved gold will precipitate out of solution as black powder. Please correct me if I'm wrong.
@@GeorgiaDogScrapper with great difficulty basically. I've had the same issue before and it becomes far beyond worth the hassle unless you have some really high grade material
@@scrappydoo7887 my problem is that the pins are thick, they are molded into the plastic with like blades on the sides of the pins. I have tried to just cut the plastic, but I cut the pin and it flips off. I end up loosing it somewhere on the floor
@@GeorgiaDogScrapper I'd suggest removing the pin bearing plastic from the board and getting a pan of boiling water and basically cook them. It will soften up the plastic and it should allow you to pull them straight out. I've done it in the past and it's worked well but without knowing exactly what you are working with it's hard to guarantee that it's going to work. If you give it a go I'd suggest you do it outside or in a well ventilated area.
@@scrappydoo7887 thanks, I will have to try that. I have around 3 lbs of connectors that have gold pins and it would take forever to cut the plastic and remove the gold pins. I also have to see what it takes to get the gold off of boards, I have several boards that are gold masked under the masking. I need to get it to where I can recover my precious gold from these components. Thanks for any advice.
@@adambuysyuckyhouses usually only if you keep dosing it with peroxide or if you have very concentrated peroxide. Realistically the peroxide should only be used as a kickstart to the process of copper chloride and an air bubbler
If the pins are 95 -100% encapsulated in gold plate, the AP solution will have a lot of difficulty permeating the gold to attack the base metal. To speed the recovery process, it would make sense to mechanically distress the pins to expose more surface area of base metal for the AP to attack. I'll bet a handful of those pins and a couple of quick power bumps in a cheapo, expendable yard sale kitchen blender would nick them up enough to be effective. Any gold removed can easily be recovered from the blender and added to the pins in AP solution.
Too much time spent with AP. If i do it, i doit direct AR, add sulfuric acid at the end of reaction to precipitate silver/metastanic acid, add some ice too cool down, filter, precipitate, washing, dry, weight and melt, that it in jyst few hours! Even on big quantities like he has, is still not so expensive. Here in Romania 1Kg of HCL and Nitric, is just around., 3 euro each!
Niemals weiter Wasserstoffperoxid hinzugeben!!! Durch die erneute hinzugabe von Wasserstoffperoxid lösen sich die schon abgelösten gold folien auf ! Dies kann man für den nächsten schritt tun nachdem man die lösung gewechselt hat um das gold aufzulösen

I just did 347g of pins and got 7.5g gold! These were late 60’s pins.
Was that after cleaning ect?
I only ask because that's quite a yield 👍👍

What do you mean by wire wrapped boards? It's not a term I have come across
@@scrappydoo7887 They were development/prototype boards and other custom components, look at boardsort under wirewrap boards.
@@MickNailZ my apologies, I misread your reply.

So if you bubbled pure oxygen it would work faster?
Which filter paper are you using for gold foil filteration?
Not critical. The foils are large. Even coffee filters would work well.
If you use coffee filters for foils most rinse out into beaker easily. No need to use ashless lab filters, just toss those with other old gold filters.
And cottonballs with foils is annoying in my opinion. 😂
Better for finely divided material.
Did u test
Gold ex?

Ap will dissolve a bit of gold if you put too much hydrogen peroxyde it why i prefer cucl2 ( hcl and burned copper to start it)
I believe you are correct, but as more copper goes into solution the dissolved gold will precipitate out of solution as black powder. Please correct me if I'm wrong.
Acid lowers pH.
How can remove gold from pins that are stuck in plastic. I can't get them out, they continue to just break off inside the plastic.

There was 800 ml. After 2 weeks we can see allmost 1000 ml.
