I stopped wasting my hard earned money on gold filled scrap to refine . Now I'm strictly just buying solid gold to refine best decision I made. First best decision was to follow your channel
I don’t understand why you want to refine solid gold, can you give me a quick explanation? New to all this stuff.I understand why you’d do that to the unpure stuff. Thanks,
I love your videos, Sreetips! I can recite by memory all of the gold and silver refining steps using inquartation and aqua Regia. You really opened my eyes to other methods.
Every video gets better and better, I love what you do, and how you explain it in simple terms. It's very relaxing to watch and super exciting to see the end results, thank you!
I've left. Other comments before . What really impresses me is the military standard you set in your videos. Being military myself as a department of the navy in the fleet marines Usmc .the detail in your instruction is self evident. Top notch .outstanding. I've learned a great deal.
Thank you very much I found the video that shows the calculation of gold for purification is extremely useful I already watched the video that shows the calculation and I can do the calculation without problem thank you the video that explains the calculation was posted on February 6, 2023
@@lvstofly I would be interested in it too. But I think he'd probably have to seal it some way to prevent leakage during shipping. I think an amount containing exactly one gram of gold would be a good standard. And if it were concentrated to the deep orange color, it would be amazing!
Hi Mr.Sreetips. Thank you for your content you make. I have been watching your channel for probably 4 years mabe even more it feels like and Im very glad I found your channel. I was wondering if you will ever make a video of all the equipment you use to film and how your setup works and looks??? I think it would make for a interesting video. I want to start a cooking channel😅 and it would be informative to see your setup.Hope you get time to make a video on this topic if you want to and when you have the time one day.Hope you have a great day and thank you.👍
I love your videos and thank you for doing this process. I think the growing of silver crystals in the electrolytic cell is a beautiful process and was wondering if you could do the same for gold. I will be looking forward to the watch this process, seeing the growth over several days, the final yield and length of the metallic crystals. I have seen natural formations of gold crystals, which are beautiful, and eager to see the final results. Thank you for enquarting (sp?) chemistry with art!
Great video! I was hoping that someday you will make the electrolytic gold cell, but no so soon! Also, I'm a little worried that the titanium cathode will not work as expected, that's because titanium is way higher in the electrochemical series of metals, meaning you would need to supply additional voltage to force the gold in solution to precipitate in the titanium cathode, besides that, that electrolyte looks pretty good! I can't wait to see your next video, I'm sure you will get some shinny gold crystals for sure!
I'm trying to figure out why sreetips is using a titanium cathode anyway. I thought from his other electrolytic gold refining that the gold precipitate is permanently bonded to the cathode. Why would a titanium cathode be used for precipitating gold?
@@SuperDavidEF I was wondering the same, in his silver cell he uses a stainless steel cathode, maybe gold doesn't bind to titanium because of the titanium oxide layer that forms on its surface in such aggressive solution that prevents metal to metal contact? If that's the case, that possibly applies in the stainless steel cathode too, where the oxide layer is formed by the Chromium and prevents the silver from strongly binding to the cathode.
ow awesome awesome awesome, I've been thinking about the Gold cell lately. I do notice you pass one of the parameters. Current density. 125 Amps per square foot. I'd converse that to metric to do math with that.
Hello Sreetips I think You could reduce amount of copper on the sterling silver by sulphuric acid pickle before loading the anode basket, thus reducing copper contamination of the nitrate, regards George
If your process can make a profit, all you need is the first batch. Otherwise you can keep it, and you're basically just putting money in the bank at interest rate = inflation.
This is the series I was hoping for! I'd like to do electrolytic purification of my forthcoming gold, as it requires so much lower total volumes of reagents, and thus much less waste. Electricity is DIRT CHEAP where I live, so it'll be VASTLY more cost-effective too.
I found Hoke's book online free in .pdf form. Just do a search for "Refining Precious Metals Wastes by CM. Hoke" That is the name of the book and the author.
@@MrThorp1 Cool I'll have to try to find it if I get impatient lol. Yea I imagine they don't get as big and spikey but still looking forward to the "growing gold" bit of it.
when i get caught up with life i will start, but will be hard to back track over the period to find the steps that you proven was more effective, but can't wait excited to pass on to the next generation thanks for the videos watch soon as i see it , always on the top row of my views to see because i watch mutliple times when bored =)
Question from someone with no experience, just thinking about a step in terms of physics. After SMB precipitation, you allow the solids to settle at room temp (depending on exothermic effect on temp). Would instead boiling the precipitant gold settle the solids better owing to decreased density of the liquid? Could this reduce waste from pouring off? I almost hate to ask this question, because I find the waste container refining vids incredibly satisfying.😂
It's crazy to me that you can instantly see a change in the metal and the color of the nitric acid when you pour the used nitric onto the metal the first time.
Hello Mrs and Mr sreetips. A big thanks to Mrs sreetips who provide Mr sreetips whit muth gold, so whe can enjoy this canal 🌹. Whis everybody a nice day. Arne
Do you know roughly what purity the gold is after the nitric acid step? I'm wondering if high purity wasn't a concern if you could just skip the aqua regia step entirely.
If i was more of a gambler id wager the cloudiness of your solution was very fine silver chloride in suspension. Its so fine even slow lab filter paper doesn't easily catch it. I have better luck using the cotton ball jammed into a funnel method if filtration. The liquid of the solution wicks down the cotton fibers leaving that ultra fine particulate behind. If it was me before that though i would dilute it with water by a lot to ensure wll the silver was kicked kut of solution before filtration. Takes longer but makes for a cleaner initial drop. Cuts overhead costs in the end. My 2¢
I agree with those above that are excited to see this in action! I would love to see a video about your melting set up, where do you use propane vs. aceteline. Would be very interesting. Let me know if you've already covered this!
How is lithium recovered from all the junk e-vape batteries people are now lining the streets with? Is that shit gonna leech into the ground water and make us even dumber?
Is that titanium grade 1 or 2 because any other grade will contain impurities and maybe unusable or needs pre treatment in hot 20% HCl just to destroy any other metals on the surface that will be a problem later. Overall the only worry is aluminum which is ampotheric and will be put into solution as gold plates onto it and maybe silicon in very trace amounts.
You can tell my guy here has broken a few beakers. Look how he adds the ice . And it's over another container just in case . This tell me that even sliding the cubes down the side can break a beaker .. lol
I see the fumes going up in your hood, and your talking like you aren’t wearing anything over your mouth/face… is there a shield on your fume hood to block those fumes from you before it’s extracted out? Also, have you ever breathed in any of the fumes that you have worked with? (dumb question, but just curious 🧐)
The fume hood has a strong daft that pulls the deadly fumes away from me. I’ve done chlorine gas, SO2 gas, nitrogen dioxide, and never caught a whiff. There’s no way to safely do these reactions without a fume hood.
25:46 it also says you need 10% free hydrochloric acid in the mixture and you didn’t mention it so since this is your first time I wanted to make sure that wasn’t an oversight on your part and produce an undesirable result. Anyway I guess you can adjust your concentrated mixture with water up to 180 mL and add 20 mL of hydrochloric acid 🤷🏻♂️ I’ve been following this channel for a few years now and I can’t wait to see the results of this particular experiment
This isn't his first time. Sreetips has some older videos of doing this process. He used a gold cathode that time. I'm interested in finding out why he decided to use titanium this time. He also has some other refiners (or at least one) that he gets ideas from and help when he needs it.
What is the cost of the process of refining gold/silver? Just wondering how much it adds to the investment cost. Also curious if you are picky with what you melt and what you keep as I would imagine some of the jewelry and chains would hold a higher value in their jewelry form.
Sreetips, when you're pouring off the liquid after the SMB, why don't you run it through a filter in the waste container? Wouldn't you capture the gold that pours off in the filter? You could just burn the filter and have the gold, right?
I have much sterling that must be dissolved. So why not use it to inquart? Like refining both metals at once. Using cement silver to inquart is not recommended. The PGMs will tend to build up in the silver. And that could cause problems in the silver cell.
Great video , I guess if you have a lot of money and time , but for me , bust ,crush , smelt ,then remove ,gold from silver , this will help for that part , and for purifying , my family members have perfected this in the old days you might of heard of Englehardt gold .
What was the point of adding the silver in the beginning? After you melted it all together you ended up pulling the silver and other metals out of it anyway. So why do you add silver in the first step?
I try to avoid that by cutting it open. And wouldn’t you know it, as soon as I begin shooting video it does that to me. I must have over-looked that piece.
Premixing aqua regia 3:1 or 4:1 is antiquated and not used by modern refiners. It’s much better to use incremental nitric dosing instead. I can dissolve an ounce of pure gold powder in 150ml hydrochloric acid and 15ml to 18ml of nitric acid.
And do you know or do you have an opinion based on the knowledge that you have major companies like out of Switzerland and all these other shoes gold refining companies is it easier to do it electrically or chemically when it comes to Gold processing and refining
Is there anyway you can DM me I would like to pick your brain about some nitric acid that could possibly be contaminated. Any help would be appreciated.
Is it possible to grow gold in an Electric cell , the same way the silver crystals are grown? Just curious to know if it could even be achieved? Thanks
I bought all equipment and glassware on eBay accumulated as I needed it. Consumables mostly HCl, nitric, a little sulfuric, and some SMB. That’s about it.
