You’ve got to go hunting. It won’t fall in your lap, even though it feels like it does when someone goes in their house and comes back out with a hand full of scrap gold and puts it in your hand

Sr. Chief, question about the construction of your fume hood…I noticed the roof being canted forward from the rear to the front (operator opening). Wouldn’t this design bring the fumes in proximity to the operator?
Just noticed one thing that might have been an issue if unlucky: You rinsed the lids into the filter setup for the silver nitrate. While I understand it's habit to do this to transfer everything across chemically (practiced chemists do this without even thinking), it would be a problem if some of the nitric spattered onto the lid from the boiling nitric solution. You went through a lot of trouble to make sure all the nitric was consumed but by rinsing the lid into the final solution you might inadvertently reintroduce some nitric again if it's on the lid.
I also use cement silver for my electrolyte. It has a slight blue tint to it from copper contaminants but that helps grow chunky crystals I've found. I pour my sterling into anode bars directly, too. If your goal is volume, that setup works just fine. After each crystal harvest I'll precipitate out the silver, clean it, then redisolve it, instead of using crystal. This allows me to recycle the electrolyte while turning around and selling the (poured) crystal. I am comfortable with only 1 run, though, with with cement as electrolyte. I know you are able to get more runs out of your electrolyte so there is certainly an advantage there with your method.
I used cement silver to make electrolyte for my first batch ever. The problem with using cement silver for electrolyte is palladium. Since it is soluble in just nitric (the only one of the six PGMs that is) it can build up in the cell electrolyte and start plating out with the pure silver crystal. This could cause it to contaminate your pure silver crystal. Bad enough, contamination of your silver, but worse is that palladium is 100 times more valuable than silver. A fraction of a gram of palladium is worth more than the ounce of silver that carries it. You can have as much as 10% palladium contaminating your silver before it becomes noticeable
You’ll recognize palladium in your electrolyte because it will turn green (copper is blue plus palladium is yellow = blue plus yellow makes green). I have a video that shows green silver cell electrolyte and I use DMG to remove the palladium.
Just so i understand mechanics here! You desolve the pure silver for electrolyte, pass low voltage and amp current through cell fill filter basket with impure shot to refine, but does the pure silver you you desolve for electrolyte also replate out as a double refined silver also?
Hi I sent sum gold plated and gold filled jewelry into a refine place through this shop guy and he only gave sum gold back from it , no silver or other materials.. is that suppose to happen? I thought I was gonna get gold and silver not just gold from it.
gold plated and filled jewelry typically doesn't have much silver as it isn't usually plated over a silver core usually some other base metal. karat scrap is typically gold mixed with silver so there is a little more silver in that but still at best a few grams depending on how much you refine.
Question on the action taking place in the Cell: How do you know the silver crystals that are forming are not coming out of the Electrolyte solution that has 600 g of silver in it to start with? i.e., how much of the silver harvested comes from the shot vs electrolyte?
Sreetips do you recover any of the silver that is used to make the electrolyte? I also agree with you on the value of coins. The jewelry piece with writing on it says "dissolve me".
@@sreetips I was wondering if the 500 grams you use to make the electrolyte, if you recover it while/when you are running the silver cement in the silver cell and is that why you need to make more electrolyte is all the silver in the electrolyte has been reclaimed.
@@kirahund6711 after I asked that of him I realized what he was saying. The electrolyte is just silver nitrate at that point the other acid was depelted and it is a constant cycle of recovery. I would think the copper would be seperated in the soaking in copper process when the silver cement is created and the silver nitrate had changed to copper nitrate. The sludge in the basket would be more platinum metals that cemented out with the silver. I really don't know though. It would have to be a passionate hobby to turn a profit. He sells the good pieces and probably turns a fair profit on them as well. Plus with the jewelry he refines the gemstones are taken out. Throughout history precise metals and gemstones have been worth something. If this hobby was applied for a few decades with the way inflation and markets go, it would be well worth the time. Just for the simple fact it's basically reinvesting your money. The high in 1991 was $4.50 per ounce. There's ways to lower energy cost. Energy is typically being used when your at the house anyways. Does that hotplate use that much more energy than a TV or a computer.
Thanks for showing this, I've been curious about your electrolyte and how the silver cell works. Curious how long the electrolyte lasts before it needs to be replaced? Do you keep it topped off with distilled water? Thanks for all of your videos, I've become a Sreetips junkie in my spare time.
It depends on copper concentration. Never use it more than twice. The silver in the electrolyte gets depleted as the cell operates. To compensate, I dissolve some more silver and top it off.
Can I purchase the electrolyte? I could run a silver cell without the need for the toxic acids and ventahood. I just need the electrolyte. Is silver nitrate on Amazon the same thing?
I try to get two uses from one batch of electrolyte - the silver depletes out of the electrolyte as the cell operates - it gets plated out along with the dissolved silver from the anode basket
@@sreetips didn't know this. Guess this would accelerate the copper percentage in the electrolyte. feels like an accurate test for Ag and Cu concentration is a must for running an efficient cell with minimal maintenance
@@thereverendcoyote Yeah, I guess with care and a little math you could weigh the metal going in and the metal plating out after a set time with a set starting concentration of electrolyte and figure out the approx Cu concentration and replenish with water and AgNO3 until the Cu gets to the upper limit. When I finally start my cell I will do this...
Great point. I was wondering what could have been inside the metal but it may have been on the outside. I didn't see him incinerate the coin before dissolving it
That number may have been for sterling/925 silver, not pure silver. Copper is alloyed with silver to make sterling/925. Copper takes more nitric to dissolve it than silver does.
Got a question, you ever come across computer components that has gold foil and gold powder in them when in hydrochloric acid and hydrogen peroxide 3%???
@@sreetips ok, I put 100pcs R2P LOT Dual DIE CPU LGA775 Intel Xeon C2Q Processor in AP the foil started coming off with a metallic powder I think is copper. I didn’t expect copper to dissolve like that in AP but it resembles gold when in power form so it’s still in AP I’ll play with it more when it’s all finished.
I have a few ounces of silver crystal for sale on my eBay site. The ask is a hundred bucks. But other than that, I’m not wanting to sell any of my silver. Selling silver, with the spot price so grossly undervalued, would be foolish. I feel like I’m getting cheated selling it for a hundred bucks per ounce on my eBay site.
Not sure, I started in my garage and just accumulated the stuff over the years. I had a Chem lab in grade school in my basement. This is kind of an extension of that.
Good sir, I know you're always careful but please remove the top of the dripper only after plugging on the tube next time. ;) Always a pleasure watching you at work. Stay safe and all the best.
@@sreetips can we use copper nitrate solution as an electrolyte and use graphite electrodes to extract copper? I have a plenty of copper nitrate solution going as waste. If not, can you tell me how else can I get copper from copper nitrate solution.
In the future, a quick three-second dip in E-Z-Est coin/silver cleaner would make silver jewelry pieces like those pop. Could probably get a decent amount more for them on eBay after cleaning.
A couple of additional suggestions for your Silver Cell. You might consider some Automotive type weather packed connectors in your next harness assembly. The Alligator Clips, you might also line them with a little Dielectric Grease, AKA: Automotive Light-Bulb Grease with will conduct electricity, but will help control the corrosion factor on your connections. Next on your Stainless Bowl, you might also solder some connector tabs to the bowl, then use a weather packed slide connector or bullet type connector. The contact should be better than the alligator clip(s), and instead of constantly connecting and disconnecting at the bowl. For the Anode end, the alligator clip will have to be used. Just a thought...
Beautiful coin!! I think people got upset because it was so beautiful and the fact that those 10 oz Maple Leafs are hard to come by they probably wouldn't have cared if it was 10 Single ounce Maple Leafs because they're a lot more plentiful but Awesome video I really enjoy your precious metal videos keep it up brother
the part that always gets to me is the effort put into making the commemorative coin and to make it look the way it is. Why If I reach a point I am actually making money and can get things like silver and gold. I will get simple bars. Simply cause I would get to attached to commemorative fancy looking decorated coins and such and if I was gonna melt. I would much prefer a lump or rectangle. As I don't think I could watch something with so much detail melt.
@@kdm1234gmail yeah I know what u meen I have a bunch of Silver Eagles and I could never picture myself melting them and if I needed some money I think I would sell my silver bars first because like you said I'm kind of attached to the Eagles
I think the purple stone is charoite, and the red stone with the yellow streak in it is mookaite. The stone you are referring to as hematite is marcasite.
I have a couple of silver ingots I made from scrap sterling silver. I suspect the copper may be high in 1 of them as it doesn't seem to shine completely silver & has a slight coppery sheen. how can I refine it to 999 without nitric acid as I live in UK & you can't get nitric acid here (or the home chemicals from your other video). is there any way of refining it with what's available in England? If I melt & repeat with borax would that remove the copper?
Melting and borax will not separate the copper from the silver - it will cause them to alloy. You could try using a silver cell on the sterling silver. But with copper that high the electrolyte would become saturated with copper quickly. Silver nitrate crystals dissolved in distilled water can be used for the electrolyte.
Thanks for your reply. if I was to use silver nitrate crystals to make a silver cell would the copper affect the solution to the point where I'm experiencing high losses anyway? wish I could just get nitric acid. it would make the process so much easier.
@@iananderson4572 Ian, I use cement silver melted into granules to feed into the anode filter basket. It’s about 99% pure with copper as the main contaminant (also traces of gold and platinum group metals). Feeding sterling/925 silver (it’s about 90% silver and 10%) into the cell will work, but the electrolyte will quickly become fouled by the high copper content. After about 60g per liter copper concentration, the copper can start to plate out with the pure silver thus contaminating the pure silver crystal.
@@sreetips 2HNO3 + 2Ag → 2AgNO3 + H2 Molar mass of nitric acid is 63.012g/mol. Molar mass of silver is 107.87g/mol. We need 0.584g of nitric acid per 1g of silver. With 68% concentration we need 0.859g of nitric per 1g of silver. Density of 68% nitric acid is 1.41g/ml, so we need 0.61ml of acid to dissolve 1g of silver.
*People: 'oh no you nicked a coin!'* *Sreetips: 'OK how about we dissolve the entire thing, that should take care of the damage issue and make it all bit more useful'*
What your videos did to me!?, I’m addicted watching them all day 😵💫 Is it because of what it’s called “fever gold”? or the charismatic way of your optimal explanation method, maybe both… “Thank you”
I think 100g per liter will work. But the silver in the electrolyte become depleted as the cell operates. It plates out on the cathode. I like having extra silver available in the electrolyte. If it gets too low then the copper could start to plate out and contaminate the pure silver crystal.
@@sreetips Thanks for responding. Yes, the silver concentration in the electrolyte will decrease as copper oxidizes. But the silver content should remain pretty stable, since the ions are being replaced by the silver being oxidized at the anode. In theory, copper and other base metals should just go into solution, not be reduced and plate out on the cathode. Some copper is going to get to the cathode, regardless of what is done - but I don't think it has been absolutely determined how it ends up there. It may be due to copper ions replacing silver atoms on the cathode long enough to get physically bound into the silver crystal matrix. In other words, it may be similar to the silver dropping out of a silver nitrate solution when a copper strip is immersed - long enough for the copper atom to get trapped. Copper contamination can be reduced by making sure the pH of the electrolyte does not get too low (acidic). I seem to recall that current density also has some effect. Have you checked to make sure your voltage is not too high? I seem to recall that the voltage across silver refining cells is kept to about 0.85 volts. Buy my memory on that point if fuzzy and I cannot find my copy of Hoke to see if there is any information there. I think too high a voltage could force it into an electrowinning condition for copper. Here is a reference you may find interesting: www.metallurgie.rwth-aachen.de/new/images/pages/publikationen/chaellenges_in_id_6420.pdf It is a paper on Pd and Cu contamination of cathodes in silver electrorefining.
@@sreetips Interesting. I would think that would only happen if the electrolyte was totally saturated with copper ions. Copper does oxidize before silver. Also, the silver ions will reduce at the cathode before the copper ions. But it surprises me that it could be so complete that almost all of the silver ions were gone. Was copper plating out on the cathode?
typicially a stoichiometric excess of acid is used because some will break down or boil off in the process but also because using exact equivalent of acid would take forever for the reaction to complete
Rounds and coins are both nice as long as someone wants to buy them. You can put a value on something but it won't buy you a sandwich if you can't sell it. Coins are usually easier to sell, though. Coins are legal tender for a country and have a face value for those who may not know much about it while rounds, which are not legal tender, are considered bullion. I assume that is legal tender and not just a nice round? What did the reverse look like? Was it a Maple Leaf?
that silver coin is worth way more than his amateur smelting job. Because it's from the Royal Canadian Mint anyone dealing in precious metals know it's the highest quality globally
When I saw 1.22ml i was like oh no way too much. I normally use 1ml or slightly less at .90 ml of nitric per gram of silver crystal when I’m making my electrolyte. When you cover the beaker it keeps more of the nitric in the solution instead of out gassing it. great video as usual!
@@captron7814 pretty much what I do I usually use 300 g of electrolyte for my 2L cell. I start with 300 ml of water and 200 ml of nitric and add from there. I almost always end up at less then 1ml/g. A little trick I use is cover my beaker with a watch glass then put a paper towel in the spout. It keeps a slight positive pressure in the beaker and doesn’t let the nitric release the nitrogen dioxide so easily. Its actually interesting to see no fumes then lift the watch glass and see a bunch of fume production. This trick cut my nitric usage by at least 20%.
@@gsracer nice. I'm in the process of setting up a silver cell. I've been accumulating as much silver as I can get under spot to refine because I think its about to skyrocket in price. Now I need more gold so I can refine all this flatware
@@gsracer I have my electrolyte made from silver shot and it's a little lighter blue color then Windex. I figured I'll be able to get enough crystal to make clearer electrolyte. I have everything together including filters, I just need to set it all up now. I even have around 500g of shot to start with.
@@captron7814 try cement silver that made from silvel chloride. If you wash the cloride properly before you convert to oxide than silver metal , you most likely get 999 pure silver. Don't forget to melt the cement silver before you dissolve it for electrolite.This is how i started my silver cell first time and work like a charm.

I've got to say, that as a bit of a coin collector myself, I was aghast with what you just done. However, I do understand the different perspective. The black stuff in the solution was probably some lacquer to keep the coin from tarnishing.
Still confused why you put pure silver into the electrolyte to make silver crystal. If it’s already pure silver, what are you accomplishing by using pure silver to make pure silver?
Viewers - "you ruined that coin", Sreetips - "watch this".
Turns out they got butt hurt over a crap filled paperweight. Bahahahaha
Exactly! 🤣
He should have t-bagged the electrolyte to make the trolling complete.
😂
If the coin was 2018 or later the black stuff was probably what the mint calls “Mintshield”. It’s coating applied to keep the coin’s surface pristine.
I expect heating the coin to red heat might have burnt off the coating.
@@roberthayward9299 i know he typically incinerates, but this time he didnt show it and the coin looks awfully unoxidized

Canadian Mint doesn't mess around. If they it's 99.9999% pure silver. It is.
Most silver is .999 fine not .9999, so it could just be a small amount of impurities. But that does seem like a lot for even three 9.
If it's > or = to 2018, that black stuff would likely be the mintshield coating to prevent milkspots and tarnish.

This allows me to recycle the electrolyte while turning around and selling the (poured) crystal. I am comfortable with only 1 run, though, with with cement as electrolyte. I know you are able to get more runs out of your electrolyte so there is certainly an advantage there with your method.
I used cement silver to make electrolyte for my first batch ever. The problem with using cement silver for electrolyte is palladium. Since it is soluble in just nitric (the only one of the six PGMs that is) it can build up in the cell electrolyte and start plating out with the pure silver crystal. This could cause it to contaminate your pure silver crystal. Bad enough, contamination of your silver, but worse is that palladium is 100 times more valuable than silver. A fraction of a gram of palladium is worth more than the ounce of silver that carries it. You can have as much as 10% palladium contaminating your silver before it becomes noticeable
You’ll recognize palladium in your electrolyte because it will turn green (copper is blue plus palladium is yellow = blue plus yellow makes green). I have a video that shows green silver cell electrolyte and I use DMG to remove the palladium.
Just so i understand mechanics here! You desolve the pure silver for electrolyte, pass low voltage and amp current through cell fill filter basket with impure shot to refine, but does the pure silver you you desolve for electrolyte also replate out as a double refined silver also?
Yes, The electrolyte gets depleted as the cell runs, some of it deposits on the cathode as the cell operates.
Hi I sent sum gold plated and gold filled jewelry into a refine place through this shop guy and he only gave sum gold back from it , no silver or other materials.. is that suppose to happen? I thought I was gonna get gold and silver not just gold from it.
gold plated and filled jewelry typically doesn't have much silver as it isn't usually plated over a silver core usually some other base metal. karat scrap is typically gold mixed with silver so there is a little more silver in that but still at best a few grams depending on how much you refine.
@sreetips Where do you get all of that jewelry from?
My wife gets it at yard sales and the flea market
Fantastic video once again mate, I always love watching to see what your next project is. Keep up the great work!
Thanks! Love the content
Question on the action taking place in the Cell: How do you know the silver crystals that are forming are not coming out of the Electrolyte solution that has 600 g of silver in it to start with? i.e., how much of the silver harvested comes from the shot vs electrolyte?
Most comes from the shot, some comes from the electrolyte.
that mite plat silver coin what was date on the coin ?
Was it Canadian coin? If so they have a mint shield on it so it will not milk spot. If this is any help I know this video is a year old.
That could be it. Thank you.
Would the amount of ml of nitric needed for 925 sterling me the same ratio? Or 92.5%?
925 will be a little higher due to copper being present.
Nice vid👍🏻That is for sharing⛏🏴
Sreetips do you recover any of the silver that is used to make the electrolyte? I also agree with you on the value of coins.
The jewelry piece with writing on it says "dissolve me".
Yes, I cement the silver on copper
@@sreetips I was wondering if the 500 grams you use to make the electrolyte, if you recover it while/when you are running the silver cement in the silver cell and is that why you need to make more electrolyte is all the silver in the electrolyte has been reclaimed.
@@kirahund6711 after I asked that of him I realized what he was saying. The electrolyte is just silver nitrate at that point the other acid was depelted and it is a constant cycle of recovery. I would think the copper would be seperated in the soaking in copper process when the silver cement is created and the silver nitrate had changed to copper nitrate. The sludge in the basket would be more platinum metals that cemented out with the silver. I really don't know though.
It would have to be a passionate hobby to turn a profit. He sells the good pieces and probably turns a fair profit on them as well. Plus with the jewelry he refines the gemstones are taken out. Throughout history precise metals and gemstones have been worth something. If this hobby was applied for a few decades with the way inflation and markets go, it would be well worth the time. Just for the simple fact it's basically reinvesting your money. The high in 1991 was $4.50 per ounce.
There's ways to lower energy cost. Energy is typically being used when your at the house anyways. Does that hotplate use that much more energy than a TV or a computer.
Thanks for showing this, I've been curious about your electrolyte and how the silver cell works. Curious how long the electrolyte lasts before it needs to be replaced? Do you keep it topped off with distilled water? Thanks for all of your videos, I've become a Sreetips junkie in my spare time.
It depends on copper concentration. Never use it more than twice. The silver in the electrolyte gets depleted as the cell operates. To compensate, I dissolve some more silver and top it off.
@@sreetips What do you do with the waste?
Waste treatment
@@sreetips The bucket with iron plates cementing everything out?
Yes
Great video nice lesson
Can I purchase the electrolyte? I could run a silver cell without the need for the toxic acids and ventahood. I just need the electrolyte. Is silver nitrate on Amazon the same thing?
Yes
Question for you Chief. How often do you have switch out your electrolyte?
I try to get two uses from one batch of electrolyte - the silver depletes out of the electrolyte as the cell operates - it gets plated out along with the dissolved silver from the anode basket
@@sreetips didn't know this. Guess this would accelerate the copper percentage in the electrolyte. feels like an accurate test for Ag and Cu concentration is a must for running an efficient cell with minimal maintenance
@@thevalleyofdisappointment I know there is Cu going into solution. That is why the electrolyte goes from clear to blue.
@@thereverendcoyote Yeah, I guess with care and a little math you could weigh the metal going in and the metal plating out after a set time with a set starting concentration of electrolyte and figure out the approx Cu concentration and replenish with water and AgNO3 until the Cu gets to the upper limit.
When I finally start my cell I will do this...
my guess for the junk in the coin solution is that its polish or wax or lacquer something they might have used to preserve the coins shine.
Great point. I was wondering what could have been inside the metal but it may have been on the outside.
I didn't see him incinerate the coin before dissolving it
Can you put silver cement directly in to the cell basket
No, I clogs the filter
is it safe to assume the coins to dissolve for electrolyte will be pure silver?
Should be ok if they are 999
I can't seem to find your ebay store. Please help

What is the gas given off the yellow smoke?
Not sure, it’s similar to nitrogen dioxide
do you think it was supposed to be 1.22 grams of silver per ml of 70% nitric?
That number may have been for sterling/925 silver, not pure silver. Copper is alloyed with silver to make sterling/925. Copper takes more nitric to dissolve it than silver does.
@@sreetips oh ok thats makes sense! good job!
Got a question, you ever come across computer components that has gold foil and gold powder in them when in hydrochloric acid and hydrogen peroxide 3%???
I’ve used A/P solution to recover gold foils from computer scrap.
@@sreetips ok, I put 100pcs R2P LOT Dual DIE CPU LGA775 Intel Xeon C2Q Processor in AP the foil started coming off with a metallic powder I think is copper. I didn’t expect copper to dissolve like that in AP but it resembles gold when in power form so it’s still in AP I’ll play with it more when it’s all finished.
Do you sell your silver you get from your cell for the current asking price?
I have a few ounces of silver crystal for sale on my eBay site. The ask is a hundred bucks. But other than that, I’m not wanting to sell any of my silver. Selling silver, with the spot price so grossly undervalued, would be foolish. I feel like I’m getting cheated selling it for a hundred bucks per ounce on my eBay site.
How much would it cost to make a lab like you have?
Not sure, I started in my garage and just accumulated the stuff over the years. I had a Chem lab in grade school in my basement. This is kind of an extension of that.
Just found theses videos, what is the purpose of silver crystal?
It’s high purity elemental silver used to produce investment grade silver coins or bars close to five nines
Good sir, I know you're always careful but please remove the top of the dripper only after plugging on the tube next time. ;)
Always a pleasure watching you at work. Stay safe and all the best.
Which is better for gold deposition zinc or smb
SMB is selective. Zinc will drop every metal in solution and not give a good separation
Hey, I too wanna start this electrolysis based silver refining. How much time will it take for 5kgs of impure silver to be refined?
It takes me ten days to get 1.5 kilos of high purity silver. If I used two silver cells then it would be double
@@sreetips can we use copper nitrate solution as an electrolyte and use graphite electrodes to extract copper? I have a plenty of copper nitrate solution going as waste. If not, can you tell me how else can I get copper from copper nitrate solution.
I cement the copper on angle iron
In the future, a quick three-second dip in E-Z-Est coin/silver cleaner would make silver jewelry pieces like those pop. Could probably get a decent amount more for them on eBay after cleaning.
Some people think they have the right to tell you what to do with your own property.
I like that silver chain the one with the matching bracelet
How much does a cell give u per filter of silver shot? Like 5 to 1 back in silver crystal?
Obviously use alot of silver in electrolytes and in the filter I'm just curious to how much more it gives u back lol
I only get out what I put in, less impurities.
Oh I see I thought u were growing more then the original amount lol
A couple of additional suggestions for your Silver Cell. You might consider some Automotive type weather packed connectors in your next harness assembly.
The Alligator Clips, you might also line them with a little Dielectric Grease, AKA: Automotive Light-Bulb Grease with will conduct electricity, but will help control the corrosion factor on your connections. Next on your Stainless Bowl, you might also solder some connector tabs to the bowl, then use a weather packed slide connector or bullet type connector. The contact should be better than the alligator clip(s), and instead of constantly connecting and disconnecting at the bowl. For the Anode end, the alligator clip will have to be used. Just a thought...
Shane, I tried a whole new design for the anode connection. I show a little of it in the video that is uploading right now.
is that coper turning the electrolyte blue ?
Yes
Beautiful coin!! I think people got upset because it was so beautiful and the fact that those 10 oz Maple Leafs are hard to come by they probably wouldn't have cared if it was 10 Single ounce Maple Leafs because they're a lot more plentiful but Awesome video I really enjoy your precious metal videos keep it up brother
I bought it specifically to demonstrate that it can be used to make electrolyte for the silver cell.
the part that always gets to me is the effort put into making the commemorative coin and to make it look the way it is. Why If I reach a point I am actually making money and can get things like silver and gold. I will get simple bars. Simply cause I would get to attached to commemorative fancy looking decorated coins and such and if I was gonna melt. I would much prefer a lump or rectangle. As I don't think I could watch something with so much detail melt.
I prefer the silver crystal.
@@kdm1234gmail yeah I know what u meen I have a bunch of Silver Eagles and I could never picture myself melting them and if I needed some money I think I would sell my silver bars first because like you said I'm kind of attached to the Eagles
im glad someone see's where I am coming from. Usually I get yelled at.
Hello Mr sreetips. This was a great clip sir. Thank you😊. Arne
I think the purple stone is charoite, and the red stone with the yellow streak in it is mookaite. The stone you are referring to as hematite is marcasite.
I have a couple of silver ingots I made from scrap sterling silver. I suspect the copper may be high in 1 of them as it doesn't seem to shine completely silver & has a slight coppery sheen. how can I refine it to 999 without nitric acid as I live in UK & you can't get nitric acid here (or the home chemicals from your other video). is there any way of refining it with what's available in England? If I melt & repeat with borax would that remove the copper?
Melting and borax will not separate the copper from the silver - it will cause them to alloy. You could try using a silver cell on the sterling silver. But with copper that high the electrolyte would become saturated with copper quickly. Silver nitrate crystals dissolved in distilled water can be used for the electrolyte.
@@sreetips OK thank you. Don't suppose I could post them to you along with some other 925 bits. approx 100g in total. I'll pay you.
or direct me to someone who could? Think it's beyond me getting to 999 with what is available in uk
Thanks for your reply. if I was to use silver nitrate crystals to make a silver cell would the copper affect the solution to the point where I'm experiencing high losses anyway? wish I could just get nitric acid. it would make the process so much easier.
@@iananderson4572 Ian, I use cement silver melted into granules to feed into the anode filter basket. It’s about 99% pure with copper as the main contaminant (also traces of gold and platinum group metals). Feeding sterling/925 silver (it’s about 90% silver and 10%) into the cell will work, but the electrolyte will quickly become fouled by the high copper content. After about 60g per liter copper concentration, the copper can start to plate out with the pure silver thus contaminating the pure silver crystal.
For what acid concentration is the number 1.22 given?
70% nitric
@@sreetips 2HNO3 + 2Ag → 2AgNO3 + H2
Molar mass of nitric acid is 63.012g/mol.
Molar mass of silver is 107.87g/mol.
We need 0.584g of nitric acid per 1g of silver.
With 68% concentration we need 0.859g of nitric per 1g of silver.
Density of 68% nitric acid is 1.41g/ml, so we need 0.61ml of acid to dissolve 1g of silver.
Would you do the same to a American Silver Eagle?
Any 999 fine silver can be used to make electrolyte for the silver cell
Indeed. Precious metals are bought to hedge against the devaluation of the dollar, so printing $1 face value on a pure silver coin is pretty stupid.
Great video thx for sharing 👍
*People: 'oh no you nicked a coin!'*
*Sreetips: 'OK how about we dissolve the entire thing, that should take care of the damage issue and make it all bit more useful'*
What your videos did to me!?, I’m addicted watching them all day 😵💫 Is it because of what it’s called “fever gold”? or the charismatic way of your optimal explanation method, maybe both… “Thank you”
Does the electrolyte need to be so concentrated? At the strengths you use, the cell requires more than 20 Toz of fine silver for the initial solution.
I think 100g per liter will work. But the silver in the electrolyte become depleted as the cell operates. It plates out on the cathode. I like having extra silver available in the electrolyte. If it gets too low then the copper could start to plate out and contaminate the pure silver crystal.
@@sreetips Thanks for responding.
Yes, the silver concentration in the electrolyte will decrease as copper oxidizes. But the silver content should remain pretty stable, since the ions are being replaced by the silver being oxidized at the anode. In theory, copper and other base metals should just go into solution, not be reduced and plate out on the cathode.
Some copper is going to get to the cathode, regardless of what is done - but I don't think it has been absolutely determined how it ends up there. It may be due to copper ions replacing silver atoms on the cathode long enough to get physically bound into the silver crystal matrix. In other words, it may be similar to the silver dropping out of a silver nitrate solution when a copper strip is immersed - long enough for the copper atom to get trapped.
Copper contamination can be reduced by making sure the pH of the electrolyte does not get too low (acidic). I seem to recall that current density also has some effect.
Have you checked to make sure your voltage is not too high? I seem to recall that the voltage across silver refining cells is kept to about 0.85 volts. Buy my memory on that point if fuzzy and I cannot find my copy of Hoke to see if there is any information there. I think too high a voltage could force it into an electrowinning condition for copper.
Here is a reference you may find interesting:
www.metallurgie.rwth-aachen.de/new/images/pages/publikationen/chaellenges_in_id_6420.pdf
It is a paper on Pd and Cu contamination of cathodes in silver electrorefining.
I’ve seen the electrolyte so devoid of ANY silver that none would precipitate out when I added hydrochloric acid.
@@sreetips Interesting. I would think that would only happen if the electrolyte was totally saturated with copper ions. Copper does oxidize before silver. Also, the silver ions will reduce at the cathode before the copper ions.
But it surprises me that it could be so complete that almost all of the silver ions were gone. Was copper plating out on the cathode?
Yes, the silver had green in it. I ran it back through the cell a second time
Nice handling of the nitric there, the pre-placement of the lower section of the stand is much safer 😬👍
Maybe the 1,22 ml is calculated without the reflux?
typicially a stoichiometric excess of acid is used because some will break down or boil off in the process but also because using exact equivalent of acid would take forever for the reaction to complete
@@LiborTinka Ahh! It's make sense.
I think you need to do another coin, partly to cheese off the coin snowflakes, partly to see how much silver was actually in the coin.
I concur
Damn. Watched several of your videos... Earned my sub in 1:49 on this one
Welcome!
Rounds and coins are both nice as long as someone wants to buy them. You can put a value on something but it won't buy you a sandwich if you can't sell it. Coins are usually easier to sell, though.
Coins are legal tender for a country and have a face value for those who may not know much about it while rounds, which are not legal tender, are considered bullion.
I assume that is legal tender and not just a nice round? What did the reverse look like? Was it a Maple Leaf?
that silver coin is worth way more than his amateur smelting job. Because it's from the Royal Canadian Mint anyone dealing in precious metals know it's the highest quality globally
When I saw 1.22ml i was like oh no way too much. I normally use 1ml or slightly less at .90 ml of nitric per gram of silver crystal when I’m making my electrolyte. When you cover the beaker it keeps more of the nitric in the solution instead of out gassing it. great video as usual!
I usually estimate 1ml per gram to start but I only put in small amounts at a time
@@captron7814 pretty much what I do I usually use 300 g of electrolyte for my 2L cell. I start with 300 ml of water and 200 ml of nitric and add from there. I almost always end up at less then 1ml/g. A little trick I use is cover my beaker with a watch glass then put a paper towel in the spout. It keeps a slight positive pressure in the beaker and doesn’t let the nitric release the nitrogen dioxide so easily. Its actually interesting to see no fumes then lift the watch glass and see a bunch of fume production. This trick cut my nitric usage by at least 20%.
@@gsracer nice.
I'm in the process of setting up a silver cell.
I've been accumulating as much silver as I can get under spot to refine because I think its about to skyrocket in price.
Now I need more gold so I can refine all this flatware
@@gsracer I have my electrolyte made from silver shot and it's a little lighter blue color then Windex.
I figured I'll be able to get enough crystal to make clearer electrolyte.
I have everything together including filters, I just need to set it all up now.
I even have around 500g of shot to start with.
@@captron7814 try cement silver that made from silvel chloride. If you wash the cloride properly before you convert to oxide than silver metal , you most likely get 999 pure silver. Don't forget to melt the cement silver before you dissolve it for electrolite.This is how i started my silver cell first time and work like a charm.
Kevin is like the best teacher I've ever had... .. I would have studied chemistry if I knew we could do this stuff... How do ya get started now? Just go to home.depot and get some Stump Out ? I wish I could send my stockpile to someone to be refined. 25/75.
I get a better ROI selling scrap sterling to a coin shop that I can get by refining it and selling the fine silver.
How much silver is needed to make the electrolyte solution?
I use 150g per liter concentration.
@sreetips thank you for the info, enjoy watching your videos. Keep up the good work, sir.
I'm assuming that the coin was Canadian based on the engraving of QEII. If that is the case, the coin was legal tender at its face value.
You should get some custom coin molds made with your face(or your ship) on them and make Sreetips coins. Appropriate for RUclips royalty such as yourself :)
I've got to say, that as a bit of a coin collector myself, I was aghast with what you just done. However, I do understand the different perspective. The black stuff in the solution was probably some lacquer to keep the coin from tarnishing.
Still confused why you put pure silver into the electrolyte to make silver crystal. If it’s already pure silver, what are you accomplishing by using pure silver to make pure silver?
Only pure silver will work as the electrolyte
