in fact, it was a material with a very negligible content of precious metals. Maybe a few grams of silver and up to 1 gram of gold. It was clear that after electrolysis the precipitate contained a large amount of undesirable impurities. It had to be roasted and treated with Hno3+H2SO4 and then with aqua regia
Hello, I honestly doubt, that the rest is bismuth and silver, looks like some iron from non magnetic steel was pressent or other hard to burn metals (tantalum from capacitors???). Bismuth burns completely, silver and gold make one bead. XFR never showed me bismuth in bismut cupeled gold or silver or AuAg alloy... Something like that happend to me with iron, but not such huge extend and bead formed... Dont know, what to do... HCl? HNO3? Cupel more? Your guess is as good as my... I would try to cupel a small bit with more bismuth (30-40:1) in 3-5 portions, because is easier than chemical route for me... Looking forward, how will this adventure end...
Do you preheat your mold or ceramic with borax?? Wil help with the melting and not sticking to the cup. Also when using melting powder and slightly shaking the ceramic cup will help the separation process of junk and metals. Fun video, very interesting!
Try make a little cyclone dust separator for the hammer mill instead of that bag, as dust just pases right out, i know you got your mask on but it will help keep everywhere clean and you never know might make it even easier as you can just empty into the hammered mix.
The average wattage was about 250-400. 10-15v. 15-26 amp. In this case, I was going for efficiency to get it done quick. Pulling 1.5 amp at 2-3 v would take at least a week to do what I did in 10 hours with higher amp and volt. That's why I didn't like the beaker method because copper would not hold on to that stainless steel plate and would fall down because of high amps and volts.
I have, it's magnetic. Most of it was cohesive but a lot of it was falling down in chunks. I've seen that before because of high volts and amps, or it could be something else.
I had to put it aside for now. I'm working on my regular job for now to pay down some of my debt. But I do plan to get back to it, I have a project in process, but not sure when I will finish the video.
@@MetalScrapLab it's usually aluminum plated foil or ceramic and the legs are mostly tinned copper. Silver is pretty rare. Some high end audio ones probably contain precious metals but they are very expensive lol
I do talk in my other videos specially when scavenging. I really like the silence and only give information that matters. I don't want to overload people with bla bla bla.
I'm really looking forward to the next videos

I agree. I thought that cupeling would take care of that junk.
@@MetalScrapLab cupellation is used to oxidize base metals, it will not work with junk

I agree. I got almost the best mask on amazon and yet I still smell those particles.
7:30 - Can't believe you got copper like that.... i thought it was a piece of paper. It even sounds like paper
Filter the hvac pump before pump and after and have it vent exhaust away from you.i trap the gases in water in my gas traps
Hello
I found that using copper flashing works well , what’s your 7:10 wattage ?
Run 2-3 V and no more than 1.5 A , you get a really good sheet

Did you give that stainless steel cathode a magnetic test , is strange there was no copper cohesion
I have, it's magnetic. Most of it was cohesive but a lot of it was falling down in chunks. I've seen that before because of high volts and amps, or it could be something else.
@@MetalScrapLab seems to me that you would be your cementing copper out on the steel cathode/ spatula .
@@MetalScrapLab Lower current strength supposedly forms a better copper coating
Which is chemical like blue when you recovered copper? I mean chemical name and use's?
Thanks for using a mask. Way better than previous video.
Здравствуйте как долго длится процесс электролиза.
About 10 hours. I was running about 15-26 amps at about 10-15 volts.
Hallo, when the next video ?
I had to put it aside for now. I'm working on my regular job for now to pay down some of my debt. But I do plan to get back to it, I have a project in process, but not sure when I will finish the video.
Pakai elektrolit apa yang untuk elektrolisis?
Copper Sulfate Crystals. I bought a 25 lb bag from eBay.
Did you make that 100 mesh separator with the blue lid?
what about PGMs there is allot of platinum in caps
That's some very expensive copper foil you've made there
you seem have quite some LAB,
We wonder what rabit you take from high-head next ...
I don't think capacitors contain gold
I agree, they might contain some silver, but I'm not sure.

Why can't you talk ?. Silent movie went out in the 1950s

@@MetalScrapLab lol ok
In fact it is probably worth more as a components than doing this nonsense..
