[@robertbrawley5048]

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.

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.

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...

[@sreetips]

That sounds bad. It should degrade as it reacts with compounds in the seawater - hopefully

[@IZUMI_SAGIRI]

This Channel deserve way more subs

[@sreetips]

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]

There might be some palladium in those contacts. But there might be tungsten also.

[@edwardhughes352]

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.

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 😃👍

[@sreetips]

[@hateonskillz318]

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 👍

[@chadiissa5623]

[@Hossak]

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?

[@sreetips]

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.

[@Hossak]

[@ifindmetal]

Hey Kevin when you are adding liquid you are adding less if you go by the beaker because you aren’t factoring in the displacement of the metal

[@StreetMachine18]

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?

[@sreetips]

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 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.

[@hateonskillz318]

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

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?

[@youGooglin]

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?

[@sreetips]

Depends on how thick the coating of silver is. Experiment with a couple inches to determine how to proceed

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 ?

[@sreetips]

SMB is soluble in water. Just rinse over and over

[@menotume]

Dumb question ... Why dissolve all of the wire? Wouldn't it be more efffficient to just dissolve the silver coating off and discard the wire core?

[@sreetips]

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.

[@johnbackes2266]

Have you tried piranha solution

[@menotume]

@@sreetips Thank you.

[@slimpickins09er87]

Sreetips what keeps the silver from cementing off of the copper wire once the silver dissolves into the solution?

[@ruuddekoff1090]

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.

[@sreetips]

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]

Correct

[@Enjoymentboy]

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]

@@Enjoymentboy have collected some industrial electrical contacts used ones burnt , looks like gold is mixed in with it. Am I correct?

[@Enjoymentboy]

@@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.

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!

[@ExtractingMetals]

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.

[@sreetips]

How can I do that?

[@ExtractingMetals]

@@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.
