No I don't panic . I haven't watch his video in 2 or 3 years . I time has come znd gone I sure could of used these video 20 years ago when I had access to military electronics . I had 2 five gallon buckets of military spec gold plated backplzin pin. You know how many lbs of pins in a five gallon bucket? Neither do I but its atleast 80 pound minimum so I had 160 lbs of pins. I bought them from a circuit board manufacturer here in Manassas Va . Yea my chance has passed but I'm still have gold fever. It's a life long compulsion that I enjoy and don't won't to break the habit. You haven't the slightest idea what I mean. Just kidding. If you are watching this channel you got gold fever as well Consider it a hobby and you will do well as a business we good luck to that.
Have you seen any of the video coming out of Sri Lanka? a cargo ship off the coast caught fire and dumped 25 metric tons of Nitric Acid into the Indian Ocean. The country has hazmat teams removing the top layers of soil/sand/dirt from all the southern coasts affected. After watching what just a few mls of it does, seeing what 25 metric tons can do is crazy. Can't imagine the damage to the ecosystems...
Thank you. It’s a very limited interest area. Not many people want to refine gold at home. Plus most folks are clueless about gold as money. They believe, incorrectly, that paper money is more valuable. They want paper so badly that they will sell you their gold - at a discount! But this won’t last forever. Eventually people will come to realize that all fiat, whether paper or digital, is worthless. I think it will happen, fairly rapidly. When faith is lost there will be a stampede into precious metals. There won’t be enough to go around. Maybe then I’ll gain some subscribers!
@@sreetips I'm not even in refining myself, but i really do enjoy your channel, and i love how you explain things in your videos , keep up the good work ! Big thanks for the great content !
Good day. Hope you are well and your family is safe. Watching your videos and getting a lot of crucial information. I want to say a big THANK YOU for all that are you doing on youtube and explaining chemical processes. I have one little question and hope that you can find time to answer it. Several times we saw in your videos how you filtering solution using a funnel and vacuum pump. So my question is which pump (model/name/picture of the pump) you are using and which filter/gas separator you applying to protect the pump from possible pump damage of gases.
As you know I just love to point out safety tips, the fear of god entered me when you was moving the acid into the fumehood, that rickety stand is a deathtrap. Also it doesn't need to be so highly elevated, just a tiny bit higher than the destination vessel would do, which would make it easier and therefore safer to handle. Great video, lots a various sreetips action involved 😃👍
Hi Kevin. Great video. Please stay safe and sound and take care of yourself and your family members. To all members also. Talk to you later my friend. ☺☺☺😇😇😇
I enjoy your videos and do appreciate your time, I am just stock piling now. Would like to see video on contacts, ( circuit breakers , electric contacts) gold, silver, nickle recovery. Thank you .
Just bought a 999 gram of pure gold from eBay from your listing. Thanks now thats a type of investment I can get behind is refined gold bars and coins have no flexibility once you melt or alter bars or coins its pretty much over so why pay a bar or coin premium. I'll pay 999 fine gold dust/powder premium cause that means I can do with it what I see fit in doing so 👍
Hello Streetips question? I had some gold in solution I filtered and added smb I got just milky liquid Im sure there is gold in it tested it. What to do?
Nitric acid for "free" When your nitric acid is spent. you have a solution of silver nitrate and copper nitrate. Sulphuric acid and both these salts will react to give the sulphate salt and more nitric acid. I have never tried this so a little experimentation probably needed. The silver sulphate is not very soluble so you may get a precipitate but you can cement it out with copper because as the little dissolved cements out more silver sulphate will dissolve untill it all gone. (might be slow). Just a thought.
1. Is it necessary to completely digest the plated wire? I would assume that at some point all of the silver would be in solution while there is still a lot of copper yet to be dissolved. This would save a lot of precious nitric acid. 2. Adding some 30% hydrogen peroxide solution to the diluted nitric acid would also cut way down of the amount of nitric required in the digestion step.. As nitric acid oxidizes copper and silver, it is itself reduced to brown NO2 gas and lost to the air. H2O2 is a strong oxidizing agent that reoxidizes NO2 back to HNO3, essentially recycling the acid in situ, 2NO2 + (OH)2 ---> 2HNO3. You can even substitute 3%-6% H2O2 for the distilled water used to dilute the acid in the digestion step.
Hello again regarding my last question I looked again and there is mud in the bottom and tested liquid gold droped out but I must have put to much smb how to seperate? rinse with ?
Fantastic video as always. Do you do the stoichiometric calculations to estimate the efficiency of the acid utilisation in dissolving silver/copper etc at all? You know how much nitric acid it took, you work out the moles and compare it to the weight of sample dissolved etc etc?
I’m a self-taught non-chemist refiner. With the aid of professional refiners on the goldrefiningforum.com I was able to use common sense with trial and error to pull this off. Plus another important ingredient - an intense desire to achieve! I could study the chemistry and write the formulas, but for now, I don’t know how to do the stoichiometry.
@@sreetips No worries, thank you once again for the reply. I have a few issues with our electrowinning/refining issues at work and I am always curious to expand my knowledge regarding silver/gold chemistry to assist with trouble shooting. Your replies and videos are fantastic, thanks again!
Sreetips I've only been watching your channel for about a year now. I refine gold on the side but very amateur. I was just wondering if this is a hobby of yours or if this is a full time gig for ya? Your very good at it and your knowledge of your content is great.
Yeah it amazes me that everyone isn't doing a little small scale amatuer refining when most of our electronics have gold plating in almost everything. I don't use or have any set up like his but with high purity vinegar time and gold plated items you can refine is small amounts and save over time now thats a hobby I can get into te
I came across about 20 feet of at least triple ott 000 shiny clean silver coated copper wire. How much silver do you think it would render & how much material would it take?
I've been waiting for this one. didn't expect you were going to be able to not try it with nitric. :) By any chance did you ever try to see what might have been in the grey sludge left over from the sulphuric? I know there was nothing there when you melted it but I was wondering if there'd be anything if you tried to dissolve in dilute HCl.
I dilute the sludge with plenty of water then filtered out the sludge and added it to my paper storage. I’ll do a filter paper recovery video in the near future. Sure would like to get some rhodium. I know it’s in there. Just don’t know how to ID and recover it yet. That will make a good video. Rhodium is over $20k per ounce!
@@sreetips I hear you on that. I did a few hundred old sterling bracelet charms last year and they were all rhodium plated. I probably only have a few milligrams of the stuff but when I saw the price I knew it'd be worth saving.
I must do another SO2 gas precipitation with SMB slurry and sulfuric acid gas generator. Adding SMB to the gold solution does the same thing, but making SO2 in a gas generator is much cleaner for some reason
When you dissolve the lead out of the chloara-auric acid with sulphuric, is there anyway to precipitate that lead out because I would be interested to see an experiment on your waste solutions. let see how much lead is there..,, what would you use as a precipitant?
Any lead in solution with the chloroauric acid, will be precipitated out as lead sulfate. It can then be filtered out of the chloroauric acid solution to achieve a 100% separation.
@@sreetips Did you ever tried with a mixture of sulphuric and nitric, for this plated stuff, to not disolve all that copper and brass. I don´t know whats your price difference for nitric and sulphuric or if its nor necessary... ? best regards
It's not as interesting as one might think. lol Mind you I've done older ones (prior to 1969) that had almost no copper and almost pure silver inside. Was shocked with those ones. Modern ones though I don't waste my time with. So little silver that they aren't worth it to me. And most from the early 80's to present (at least the ones I've done) have had a sintered tungsten contact that is impregnated with silver. Hard to fully recover it all without a lot of time and effort. best to smash them to a powder if possible. Bear in mind this is for household breakers. Industrial breakers are a whole other story. Some of my favourites come from heavy duty hydraulic motor contacts. The size of quarters and almost a 1/2oz each. Forklifts have nice contacts too.
@@raymondutter2616 Very likely. I've had gold plated ones and gold alloy as well but most with gold just have heavy plating on them. Many of the older, high-current contacts are also high in palladium. What I have found is that if they feel abnormally heavy they are most likely tungsten.
They make and install solid silver wire . Fine stranded wire . It would be in stalled in " cant fail" military electronics i ran across some it took 2 weeks to strip it being in armor sheathing the had to unwind paper spiral stuff then pull the wire out of braided fiber insulation that was the easiest part the naked wire would come out of the braid when I compressed the end of the insulation like you do with Chinese finger cuffs. I got about five pounds znd but eventually abandoned it silver being practically worthless when sold to a refiner that was about 2013 I refuse to sell any precious metal or any scrap metal for less than 500 dollars it ain't worth the transportation cost to cash in a small load. . Sell it to some sucker on ebay. Well I didn't have internet connection back in those days. I got 30 lbs of silver electrical contacts . And it ain't worth selling either . It will all be thrown in the trash after I die
@@sreetips yea but it still very entertaining to learn from your videos . Particularly i like when you demonstrate household chemical to refine stuff. One of your video showed a drain cleaner for it high concentration if sulfuric acid. I wasn't aware of such a household chemical . I'm a big fan of hydrogen peroxide but never considered it for precious metal refining
I would guess that once the copper dissolves, it's not copper anymore, but copper-nitrate or something like that. That doesn't change place with the silver.
Nothing, the silver will cement out on the copper probably just as fast as it (the silver) dissolve forming an inefficient viscous cycle, until all the copper gets dissolved. Once in solution, the copper would cement the silver anymore. That’s one of the reasons this method uses so much nitric. It’s not very efficient.
@@sreetips have you thought about uploading to Odysee as well. They have a Lab Tab that your content would go great there. Once you create an account it links to your RU-vid account and uploads for you. Money wise they pay in LBRY crypto but viewers earn it as well and can leave support. It wouldn't surprise me if RU-vid censors this comment and is why I'm encouraging creators to expand. Rumble is another option I just don't know their pay system. Thanks for the great content Sreetips.
You write your name on a lot of stuff like glass and when the top of the R fades it looks like “Skeetips” and I’m upset I haven’t gotten a single skeeball tip from your videos
Both copper and silver are soluble in hot dilute nitric. Silver will precipitate back out of solution on the copper as the silver dissolves. This will continue until all the copper is in solution. There is a way to get silver plated off copper. I just haven’t tried to do it yet.
Sir as u do for gold plated item with sulphuric acid.is there any kind of process for silver plated item without using nitric acid.please share your valuable knowledge with us.
Second way: Concentrated sulfuric acid with nitric acid. No heating!!! H2So4 doesn't allow copper to dissolve, HNo3 dissolves silver. Then add HCl and get AgCl. Then NaOH + sugar.
You could have exploited the difference in melt temperature between the silver and the copper. This could have saved you a lot of nitric at the expense of a few cents of propane or electricity.
@@sreetipsmix in the wire with some lead in a melt dish. The lead will act as a collector metal. Heat to 961 Celsius but don’t let it go over 1000 Celsius. After it has held at temperature for a few minutes all the lead will be molten, and the silver will have alloyed with the lead. While still molten you can easily remove the solid pieces of copper wire(at this point the silver is no longer on the wire). Finally pour the alloy of lead/silver into a cupel and continue heating until all the lead oxidizes, which will leave only the silver behind as a bead in the bottom of the cupel. Then you can refine the extracted silver with chemicals like normal to get it to .999 fine. Also the wire you removed after the melt can be used to cement out the silver from the nitric so nothing goes to waste.
Good suggestion, didn’t even cross my mind. But then I wouldn’t have it to make this video. Plus, I’m wanting to see how this yield compares to my previous attempts with sulfuric acid
I plan to give my jeweler friend all his silver back once this experiment is complete. So I’m not planning on any kind of profit from this silver coated wire.
Because I refine silver also. The first step in refining the sterling/925 silver is to dissolve it in nitric acid. So may as well use it to inquart the gold. Like refining both metals at the same time - killing two birds with one stone.
Hello my friend, I would like you to help me I would like to know why I can no longer enter the goldrefining forum, this forum helps me a lot to evolve in metal refining works. I know you are a member of this Forum, I follow you there, I have been trying to enter the forum for a month and I can't, I learn many things there, I wanted to know what happened. Thank you for your help .
@@sreetips thank you my friend, I couldn't be banned, because I didn't do anything I was just learning, thank you, I'll talk to Harold. I still think it's a server issue.
@@sreetips my friend to do a second refining with oxylatic acid I add first the oxylatic according to the amount of metallized gold (chloride) with warm water, then I add NoaH sodium hydroxide dissolved in warm water? Is this the same sequence? oxalic after sodium hydroxo NoaH? Thanks.
Please forgive, I’m not a wealthy man, deeply in debt and almost flat broke. I wish I could give it away. Imagine being so wealthy that you could go around giving your metals away! I’m smart as a whip, but terrible at business. Mrs sreetips has set the prices for me. Otherwise I’d have it priced so low that it would all be gone by now!
