Cast a anode plate much easier also

Sulfuric cell

Melting is the absolute worst way

Nice bars! Melting crystal is sooo much nicer than melting cement. Those bars are probably 9999 fine or very close to it.

You could have just added nitric acid to the sodium hydroxide and skipped the step where you added the sulfuric acid

God Bless AT

Conner is here and been looking for another channel besides sreetips!!! He's my dude tho! Love your setup

I must say, very nice videos Sir! It is great to see NurdRage method incorporated into full circular refining economy! I think i will come back to see more :)

Wait this isn’t a vid about Ric Flair and the four horsemen? Dang…. Great information regardless though since I have a couple 5 gal buckets in need lol

So, Nurdrage = God. Got it :D

there is another way to get pure nitric acid the easiest way .... JUST BUY IT!

Please don't use the graham condenser, it'll back up and pressurize possibly breaking your flask. Also sodium bisulfate, not bicarbonate.

Try adding some sulphuric acid to the gold solution before filtering. Helps to precipitate out any lead that might be in solution during filtration.

I stumbled upon gold revovery by watching a Sreetips video where he had a silver cell. I was hooked

Hi Anthony, Am I correct in thinking that sulphuric acid could be added directly into the aqueous copper nitrate solution and that this might save a step as well as yield significantly more nitric acid? This should allow one to reclaim the maximum amount of nitric acid. And, ending with copper sulphate is desirable as it can easily be converted back into pure copper and sulphuric acid using electrolysis. Please let me know if I am overlooking anything. BTW; I am so glad to have found your channel. You are the first person I have seen on CZcams that has given any consideration to reclaiming acid as well as the various base metals. May God bless you and your family. Fondly, C. Chaos

Excellent video 🙏🙏🙏

Very crucial info for those that refine. Thank you for the great content Anthony 🎉

i prayed to god to stop youtube ads .

is the silver cell safe to operate inside of the house or does it give off harmful gases.

Please ditch that graham (spiral) condenser for a Leibig condenser. The Graham was only intended to use vertically. As configured, it pressurizes the distillation flask. It may just pop the joint loose one day, or it could "explode" the distillation flask. All in all, a very good instructional video.

A couple more thoughts on things to consider and ways to improve this process: First, do you actually have a need for fuming nitric acid? I haven't seen any example of a process in refining gold, silver, or copper that doesn't work with dilute nitric, and many seem to absolutely require it. Given the effort, expense, and severely increased danger of working with fuming nitric, I would avoid it entirely unless I had a specific need for it. Secondly, if you want to convert dilute nitric into sodium nitrate, lye seems like a poor choice of reagent to me. Sodium carbonate (washing soda or ph-Up for pools) and sodium bicarbonate (baking soda) are both substantially cheaper, easier to find, and safer to work with than sodium hydroxide. They also both provide a nice, visible indication that you've reached your endpoint when they stop creating carbon dioxide bubbles on addition. Third, since you always have a need for dilute nitric in your refining, I would recommend skipping the conversion step entirely. Just save the cost of the lye and put it toward buying more nitrate salts if you need to produce fuming nitric instead of converting the stuff that you already have ready to use in other operations. Keep up the good work, and thank you for sharing your processes with us. I love that this community is getting more quality content producers who are working to refine (pun intended) these techniques. 😊

I prefer to add copper to to dilute nitric acid to make copper nitrate, which can then be distilled with sulfuric acid, which gives you nitric acid and copper sulfate. Which of course you can put in your cells and recover the copper metal and sulfuric acid again.

I like your general idea...but I am pretty sure it was not sodium bicarbonate you added...probably rather sodium bisulphate. Also it is a bit unclear if your sodium nitrate is clean or a mix of sodium nitrate and sodium sulphate...would be nice if you could explain more in detail how you get rid of the sulphate ions.

Humbly and with great respect, I confirm your thanking NurdRage. I too have enjoyed and learned much from his work. As an absolute amature in the metal refining scene. So, after having used the method you show many times before your video i would politely add my own findings. In my own case I learned the following the expensive way.... 1/ the left over salts in the reaction chamber can and will destroy the chamber if left to go cold and reheated with water to clean because of uneven heating, as nurd warns of in his video.( scratch one reaction vessel) As the salts are very hot, it's difficult to pour them out safely before they set. 2/ if you overdrive this reaction you may experience a boilover, which results in a solid salt mass forming in your condensor, this results in a pressure build up in your reaction vessel. Dependind on your apparatus, you might end up with high pressure breakage and very hot salts ejecting. (Blocked condensor of your type is very hard to unblock, Graham). 3, Any small amount of nitric acid generated comes at a massive electric and chemical cost, with risk to equipment and health, at a far higher concentration to be safe to you or required to conduct silver refining anyway. I have enjoyed this channel and can learn too. I don't post videos. I refine gold and silver and sell it on an amature basis. I can see that it's possible to make extra money setting up a channel and posting videos of my work to increase my earnings. However i dont want to be responsible for ignorantly posting chemical reactions that I don't understand and causing injury to others who may be more ignorant than me even. I wouldn't want to have the pressure of posting regular videos to keep the channel alive and the money coming...... Eventhough it's up to others to do their own research. All the best and thanks.

why adding a stir bar to the powder mixture ??? is it useful ??? won't mix the powder

As cheap as sulfuric acid is compared to nitric acid, it seems like you'd just be better off buying that and distilling your nitric acid right from a nitrate salt. This method is nice if these reagents are all someone could get, or they have a bunch already on hand, but between the low yield, and the high price--I'm just wondering exactly how much it would cost to make, say 1L of 70% nitric acid, considering that can be purchased as-is for around $100. Even less would be buying a gallon of sulfuric acid drain cleaner for about $20 and using it on the copper nitrate or mixed nitrate waste products, and then electrolyzing the sulfates to recover the metal and the sulfuric acid. I've heard of people doing dry pyrolysis of Copper Nitrate directly to nitric acid but with low yields.

@10:08 I think you meant to say "sodium bisulfate monohydrate", not "sodium bicarbonate monohydrate".

The first time I did this method my finished silver had small iridescent spots throughout the bar. I wish I would’ve just held onto a small piece instead of reusing it for karat gold recovery and now my first silver cell. I wonder if it was due to some sugar or lye possibly remaining. I rinsed it until it was clear. I thought I did at least lol

Get inexpensive 'Flask' from a Goodwill or secondhand store, by purchasing cheap glass 'French Press'. It is designed to hold hot liquids and already has a great shape for chemistry. Old Coffee pots also work.

what happened to cupper sulfate with sodium borohydride ???

a beautiful artistic work ! thumbs up 👍👍

Good job sir

I love how nice your electrolysis setup is, and I'm blown away by how clean your whole lab is. I'd love to see a video on how you extracted that nice, clean nickel sulfate. 🙂

More information on the dangers involved in each step would be appreciated, otherwise, great work. I'm a top honors STEM student and DIY whizz in many areas, but never made it passed mycology for lab work, mostly. Learning how to start on a very small scale would be great.

God bless you brother

What is the situation when I pour raw silver? There is no shine in all the tin. I ask you to explain the lack of shine. Thank you very much and respect.

❤ You've peaked my curiosity ❤. I rarely respond to videos. I've been working with recycled electronics for less than a year and although I have recovered a few ounces of .999 silver and almost 15 grams of 22+ gold, I believe there's a lot more missed. I've been saving everything from my refining and now have a pile of circuit boards, about six or seven gallons of pretty much the same colored waste liquid as well as different undefined white, beige and yellow/orange powders and copper and lead bars from about 50 electronic devices. QUESTION, how do I identify this stuff 😊? (Cheaply) Your "four horse" system is a stroke of genius (👍❤️) and although my "wifie"(love you, she'll probably read this)😁 won't allow "household finances" to be used, I'll duplicate as close as possible the system with pyrex (not my wifes) from the dollar store (and a side job mowing my neighbor's lawn😂). Most acids are derived from household products , stump remover, pool supplies, vinegar, h2o2, ect... Thanks for your encouragement through the videos. It's crossed my mind that I'm crazy to continue with refining and just recycle but I really enjoy "exprementing" with chemistry and I'm not allowed to play with fire at the homestead 😁👍❤️🙏 🙏JESUS IS LORD OF MY LIFE AND THE ONLY WAY TO GOD OUR FATHER 🙏

What's got got to do with any of this?.

You don't need the bible to see that terrible times are coming.

Have you considered using oxalic acid to free the nitric acid by precipitating copper oxalate as a solid, filtering, and just boiling the supernatant nitric acid to concentrate? No distillation required. I believe NurdRage did a video on it recently.

Hello, your video showed up on my suggestions page, and I can see that you are a firm believer in God (I assume you mean the God in Christianity). I am a chemical engineer, raised in a Christian household, but am struggling with my belief. I would like to ask you why you personally believe in God? Thanks.

What size is the Aspirator bottle? Have you found any reason to go bigger like 10L beakers? Appreciate the knowledge sharing!

I still have two questions though. How is the anode bottle made and what is that round thing on the inside of the outer jar?

Great video with clear and precise instructions. I will definatley will try this method sometime.

Awesome that you put God first above all.

Good work. Really good work. I’ll to set this up at my school. I have only been doing one step at a time. Can’t wait to try.

Great Vid, thank you for posting your set-up and its operation...very clean and professional! Are you running your horsemen within the fume hood?

Great content! And I like your way being human!!!

Will a graphite anode substitute for a platinized anode to scrub the remaining metals from the dirty copper sulphate waste?
