Great video man, especially since its your first! I love how quick yet thorough you made it! Clear audio, great transitions, i love how you also displayed important information via on screen text, and so much more. Keep it up dude! You got my subscription for sure
Good video! Intersting to see this done in a fancy lab but more interesting to see this done with household chemicals ..Anyone can do it in a lab not everyone can do it with what they have on hand ...You remind me of me when I was young..I used to spend my money buying chemicals (everywhere I could find them) and doing experiments directly in the bedroom, which is not recommended.
Thank you for watching. And thanks for sharing your memories of when you were young. I do agree though, that any experiment that produces fumes should be done in a well ventilated area. Preferably outside
I'm pretty sure what you have is gold foil alloys. 24 or 22k is never used because it is too soft for electronic use. they usually come as 8-12k gold. You now need to purify the foils with Aqua Regia and you'll be surprised at how little pure gold you will wind up with. A basic rule of thumb is 1000 grams of fingers will get you 1 gram of gold.
Using more hydrogen peroxide will speed up the process. If you change out the solution every few hours it would be done quicker. For me I wanted to do it the cheapest way possible and I have time to wait. Thanks for watching
HEAT speeds up any chemical reaction. Also, if you have a way of mechanically agitating the substrates in the solution (like a repurposed washing machine) that will speed it up as well.
I save up the powder until I have a decent amount. Then I refine the powder again. Then, melt it into a small round. I then sell it to my local jewellers. They test it to make sure it's 24 karat, then they pay me.
add electric current and itd be quicker... just a tip shouldve removed the IHS off of that cpu.. the IHS is straight copper... most of your chems went to attacking the copper ihs..
I used just enough potassium nitrate to not need to de nox. De noxing is done to remove excess nitric. If you use enough to get the job done you will never need to de nox. Thanks for watching
@@goodmoodgoodday5385 if you add nitric acid very slowly, enough to dissolve all the other base metals, it's all reacted out by the time you're ready to add the SMB.
@@belvederebaileycambodia theoretically a good idea, indeed. But base metals should be already removed by treating with HCL and/or Nitric Acid before you work with AR. And most of my samples have a unknown quantity of precious metals (if even any) in it. So it seems a little tricky to me to estimate the amount of NA to add, to just get it right. Thats for I always boil out the NA, what on the other hand is time consuming.
@@goodmoodgoodday5385 you put just enough in to keep the reaction going.... until all metal is removed and the reaction stops itself. Denoxxing at the end is a pain in the ass and, I've found, leads to a less than optimal refining result.
Great video, theres a couple of things i still need hydrochloric acid-potassium nitrate/sodium metabisulfite ,can you get these 3 of amazon and the left over solution is the aqua regia ?id definitely save all my gold dust up and sell it to a jewelers
Potassium nitrate I've bought from amazon before. Sodium metabisulfite I think can be bought on there, but I get mine from another online supplier, and hcl you would get from a hardware store or ebay it might have a different name such as muriatic acid or spirits of salt
great video, I'm seeing places to buy e-waste and want a side hobby, all the ingredients can be purchased. Just really want to know how to turn the final refined product into solid gold from powder? better to know, is there a value difference in powder and soluble gold? Would I need a blowtorch? just as an easy solution.
You can use a blow torch if you want in a small melting dish. At the moment I'm using a microwave furnace. If you watch my video on growing silver crystals you can see it being used. Thanks for watching
@@3-2preciousmetalrecycling great I may look at cheaper alternatives as gasoline for the touch can be costly over time, I will look into a microwave furnace and watch your video. I assume powder gold is valuable but the real value is in solid forms, great side hobby, this was really helpful for a makeshift. 🙂
Thank you for the kind words. Powder gold holds the same value as solid gold I once sold powder gold to a jewellers. The guy melted it in his workshop to make sure it was real
For rocks, I'd probably crush them and use a gold pan to pan the gold out, alternatively try to leach the gold out with aqua regia and precipitate it with sodium metabisulfite. Thanks for watching
I thought you couldn’t produce hydrochloric acid with that condition. Don’t you need a mixture of sulphuric acid with it to catalyse the reaction and to produce hydrochloric acid.
For my understanding, it makes a weak dilute hydrochloric acid. Traditionally, hcl is made by reacting sodium chloride and sulphuric acid and liberating the hydrogen chloride gas, which is dissolved in water. When I make hcl myself, I use sodium bisulphate instead of the sulphuric acid
@@3-2preciousmetalrecycling those materials needed to this job is not easily available to every places. I have lots of assembled PCB from old gadgets such as mobile phone, emergency lighting, radio calculate but I don't know where I get all those ingredients. I have used all those ingredients in laboratory whil studying but I don't know from where I get those chemicals
Tempted to call this clickbait. It quickly devolved from "yeah, I got that stuff around the house" to "I don't have that shit in my house and nor will the pharmacy down the road".
Thanks for watching. You could use just the salt and vinegar to etch the copper from beneath the gold and bubble air through the solution . The hydrogen peroxide just speeds the process by oxidising the copper
Anyone who is starting the journey into precious metal recovery needs to watch this video. Listen to everything he says and understand it. Thank you
Thanks for the kind words, and thanks for watching 👍
I thought this was a very good effort for a first video. I'm tempted to give this a go. Thanks for the information!

Thank you folks, I have 1l 200 vol 50% hydrogen peroxide so I hope this will help to speed up
Hello and at the end how you sell this gold ?with forme or how

just one question: You put in the SMB straight without denoxxing it? Well it seems to work.

Slowly building them up. Thanks for watching
@@3-2preciousmetalrecycling youre welcome
What does it means if the solution turns yellow? Is this just other types of metals in solution? And if so which ones?
Probably iron.
You could do a stannous chloride test to ensure it's not precious metals
how much bisolfate you add? !?
It wasn't a measured amount it was just a teaspoon. Thanks for watching
Can this method be use to recover gold from rocks?

hcl
Hcl can be used. This is just an alternative way of doing it with household chemicals
@@3-2preciousmetalrecycling yes salt and vinegar reaction produces hcl, even in the food when combined
