I came across a a Chinese company that makes electrolytic Copper refining machines. The anodes are cast ingots, and the cathodes are Stainless Steel plates. In their literature they mention that the way they overcome passivation on the anodes is to periodically reverse the voltage for random amounts of time, and at random intervals. Apparently this breaks off the passive layer that accumulates. Nice trick.
I would love to see you have a bar analyzed before and again after aqua regia to see how much of what gets filtered out. Might be a cool series for you in the future!
If you used the water board to make smaller granules of the inquarted gold melt, wouldn't you likely need far less nitric to penetrate and break down the inquarted gold?
Interesting video, don't think I've seen you make a lesser quality gold bar to send to a refinary before. Nice tune also, had a bit of a Blind Melon vibe I thought, the never ending talents of Mr. Sree 👍
I have melted gold directly after the nitric boils in the past. It’s good enough like it is if it’s going to the big refiner. He will just throw it in with his next batch and re-refine it anyway.
Never boring for me. This channel is my jam. I have been trying to study your methods professor and have bought already some the necessary equipments and jewelries to use. The chemicals not yet, but will get to that later. Need to save up more money.
As a former Navy nuke guy and an engineer, when I see your silver cell videos I find myself considering how silver metal moves through the entire process. You start out with cemented silver and run it through the silver cell which of course requires silver nitrate electrolyte to operate. So part of the pure silver output gets diverted into making the necessary electrolyte. Finally, you have three output silver streams. Some impure silver remains in the silver basket, some silver remains in the electrolyte to be recovered as cement silver, and of course the purified silver crystal. Eventually, the former two streams are collected to be purified. Have you ever done estimates of the amounts that end up in each of the three output streams?
I have not. The only reason I do this is because the silver is a by-product of my gold refining. The sterling silver can be held as-is, no need to refine it. So long as you don’t try to melt it and ruin the markings.
Sreetips if UA-cam isn't paying you for these videos they should be. This is one of the most useful educational channels on UA-cam. Thank you so much for all this knowledge you're passing on
I was shocked that you said you were sending that into the refiner. Even at its current purity you would get more for it selling it on EBay compared to a refiner. What % of spot does the big refiners give you? Is it better to take the lower refiner price compared to paying the eBay fee?
Have you tried to use the silver shot to refine gold? It is basically sterling silver, if memory serves your have tried to use cement silver for gold refining ?
Using cement silver to inquart gold is not recommended because platinum group metals follow the silver and build up in it. This could cause problems in the silver cell.
Working on my first cell so I don't have to guess how many 9s to mark my metal with and it's way simpler/more efficient than running both nitric pathways. Thank you sir . Starting with the $5 Thrift shop computer power source. Thank you again. I found my local ace do not carry the dacron pre filters but ugh.. I found them on Amazon . Besides the filter I need the fuse. As I'm about to ask how long it might run and why ypu eventually stepped up to dedicated unit when your video got to the part, your unit is burned out😂. For folks out there. My set up costs ..the acid is probably the biggest expense. Scrap silver is everywhere for cheap if ypu have time to look. But even counting the silver it's less than 200 usd if you are resourceful to set up
@@sreetips it's a classical walk back in real time and a reality check. I was rinsing a large batch of cement as your video played in background. It got clear then kept getting a green mud. Eventually I found several chunks of blue crust.. looking like I'm closer to coin silver than the sterling I started with and tap water in the mix 😂😂😂😂
Excellent work, Sir! Thank you for explaining the basics to us so patiently and so thoroughly. I TRULY appreciate your kind, calm demeanor, even when accidents or mistakes happen. No needless cursing when the graphite mold fell (like i almost certainly would have done, to my own shame) no outward anger, simply "cool, calm, and collected". You are an excellent teacher 💪
Madness. It's just interesting chemistry. Helps that you see what's going on along the way. I definitely wasn't totally following where you got the blue silver cell liquid but now I do. You really have to wonder who and how people first came to discover these reactions.
I have a question regarding the copper suspension in the silver cell electrolyte. If the cathodic stainless steel bowl were unplugged from the power supply and instead the conductive lead were connected to a copper cathode placed into the electrolyte, would the copper in suspension plate out ?
Would it be worth using magnetic stirring or air agitation to keep the electrokyte constantly stirred? Or are we not too worried about keeping the current high?
I was just thinking the only video I ever remember of you pouring a bar after inquartation/before refining was when you sent some off to the refiner. I wondered if you were sending this one. It's still pretty as that girl down the street and hard to not look at her. 😉 Thank you, Sr. and BZ once again.
Yeah I’ve watched your videos on and off for at least a couple of years now, if not more, you’re a beautiful refiner. At the same time, the dragon in me, sees that sterling, and thinks to myself, why even melt down such a beautiful piece of metal when you could just lay in a bath of sterling, and low - mid karat stuff, as I also enjoy the gold 😅 again, your refining skills are always enjoyable and satisfying to watch, and I entirely understand refining this junk to something that could be used again. Not many people look at junk and see treasure
Have you ever considered instead of making a second silver cell, to just make the current one with a gigantic stainless steel bowl (2 gallon pot) and two impure silver anode baskets??? You can use the same power supply and just use two wires ??? I’ve seen it done and the results are the same except so much more silver crystal production in a much shorter period of time … just my two cents worth… regardless, I absolutely love the channel and you’re making me want to get into the refining biz !!! It will be a great retirement hobby for sure !!!
Now you have been holding out on us, you are a talented musician as well, nice touch! It really worked out well, nice addition. Thanks again for everything you do!
Hey Sreetips hope you and your wife doing well. My question is, is there any difference of growing silver christals in different temperatures? Not the surrounding temps in the room rather the temperature of the liquid in the bowl. I ask my self if you can hold the temperature at a specific level during the whole process, will it grow chrystals slower or faster? For an example - water at a temperature of 5°C can hold 12,8 mg / l oxygen. With the increasing temperature up to 25°C water holds only 8,3 mg / l oxygen. So maybe the liquefied silver needs to deliquefied faster cause of the changing liquid properties in correlation to the temperature. Love your videos. Have a good one and god bless you both. Greetings from Germany (Alex) 🙏
Can someone explain to me why the sterling is added? Still kinda confuses me. If you add sterling to the gold then just extract the silver out of the gold during the process of refining it, what is the silver actually doing to the gold? Can this be done without the silver involved?
The sterling silver reduces the gold concentration so the the nitric can penetrate. Without the sterling added, the karat gold protects the silver and base metals from the nitric acid.
Other metals COULD be used, and Sreetips has used copper before to show how it works. But, one of the biggest advantages to using sterling is that Sreetips can recover the silver, which is also a precious metal. Either way, the gold MUSY be reduced to a 25% concentration in order for the Nitric acid to remove the base metals (and silver) from it. Too much gold, and the nitric acid can't do anything.
I have two separate stock pots, one for gold refining waste solutions. And another separate stock pot for my silver waste solutions. I keep silver out of my gold refining waste, and gold refining waste out of my silver stock pot.
@@sreetips I tried to do that but most of my stuff is low grade computer parts.. I used my battery jumper on the cell. It looks like melted wax coming from the bottom of the dish.. Hopefully I get something. The big silver chunk i used was eatin up within 6 hours.
Sterling silver is a carrier of traces of gold, especially older pieces. Plus, some gold goes into solution during the nitric boils and get poured off into the silver jar. It just builds up and accumulates in the anode basket as the cell operates
2 things. 1. Looking like you're used dilute nitric flask is collecting a bit of gold. Before too long you can probably get a gram or two out of it. 2. Love the music. Another Sreetips hidden talent.
you say the powder would have been 999 pure, why is the bar less pure now, was the process not as effective as you thought? That powder looks super fine, which metals could be hiding?
I said that it was close to three nines. There’s still traces of copper and silver in the gold. The only way to get it to high purity is to refine it with aqua regia.
“Can’t you see? Can’t you see? What that woman has been doing to me.” I saw the “toad” in the melt dish you were talking about lol. How did you first start out doing this @sreetips? I’m curious because I’ve been searching for sterling silver sets and they are really expensive!! I have 3 or 4 bags of your silver cell crystals that I could use but barely any gold. I want to try this stuff out but I don’t have the money for all of the things you use. Like beakers and flasks or vacuum lines etc. Any suggestions?
Check you local craigslist. Glassware comes up from time to time. I’ve had folks tell me that the tune I was playing g sounds like “can’t find my way home” I buy sterling silver at local sales, never online.
I'd be willing to bet there is corrosion in that power supply causing the failure. They don't use conformal coating. If you open it up, take a look and find lots of corrosion your other power supply is headed for the same fate. If its corrosion than you can apply a conformal coating to protect against the acid fumes. I've used clear enamel paint or silicone conformal spray. I've used this method to protect my psu and vent fan. Never replaced either of them once they were protected. I had gone through several fans and a PSU over a 3 year period. It's been over 5 years now without any problems :-)
Yes, I refine gold. I use sterling silver, that I buy at estate sales, to refine the scrap gold. I recover the silver from that, melt into shot, and run it through my silver cell. The cell converts the impure silver (about 980 parts per thousand silver) to high purity four nines fine (9999 parts per ten thousand) pure elemental silver metal. The impure silver is added to the anode basket. The anode basket is suspended in the silver nitrate electrolyte. I pass an electric current through the impure silver. The silver dissolves, passes through the Dacron filter, travels through the silver nitrate electrolyte, and deposits on the stainless steel bowl (the cathode). The bowl is connected to the negative pole of the power supply. The process only deposits pure silver on the cathode. So I’m refining the impure silver, into high purity silver. When it’s full, I harvest the pure silver crystal, put it away and forget about it. Then I repeat the whole thing again.
Wonder how much it would produce if ya ran a taller bowl use a nice stew pot maybe I know they make a good stainless one I have one them ud just have to make a bigger basket ya hold the silver in and make it a hair longer maybe that way u could use the entire filter instead of cutting off half of it then u could make 2x as much silver
There’s a critical distance of 4 to 4.5 inches that must be maintained between the anode basket and the cathode. I did get a larger stainless bowl to experiment with.
Would it be possible to inquart using the cemented silver from the last gold refining and keep circling the same silver? I seem to remember you saying this impure silver is still more pure than Sterling.
Yes, but it’s not recommended. Gold contains platinum group metals, especially white gold. Using cement silver, over and over, would cause PGMs to build up in the cement silver because the PGMs tend to follow the silver. So that when you tried to run it through the silver cell, those PGMs (especially palladium) could get into the electrolyte and cause problems.
Something I always wondered, is there a way to predict the purity of a refining? For example, you said this was probably like 3 "9s". Had you refined it again; I know it would have been a higher purity...but would it have been like 4 "9s" only? How many refinings does it usually take you to get to 5 "9s?"
You can tell much about the purity of the gold by how it looks after pouring. This ingot was questionable, no telling what the purity is without xrf. It don’t take much to throw the purity off.
$6366 worth of gold but that is not all you got. I would love a start to finish to find out how much silver and copper comes from the same batch of gold. Any chance you have or will do a complete start to finish just to show us all the metals recovered and purified?
Have u ever taken the gold field or plated stuff and melted it down into shot and then tried to do the recovery off that or is the other metal in it make it nor easy to do or something of tbat nature I'm just curious on that part
@@sreetips gloves are definitely important. It's outside of what you normally film but it would be interesting to see the sreetips rundown on nitrile combustion.
I want to make one of these so dang bad but i dont really have a place to set it up nor one of those power supplys or a good collection of silver to feed it.... Hopefully one day in the future I'll be able to make one
When you pour your inquarted gold into the water, why not use the wooden board system that you use for the silver shot to get smaller shot size thus more surface area? Or does it really matter?
I think he tried that a few years ago, didn’t work. It’s better to have two independent cells. He is doubling his production of silver for the same timeframe. Hopefully one day he’ll have many independent cells producing silver. 😊😊😊
Can u run both silver cells on one power pac or not,can u please let us know when u do the next video on the silver cells please. Love your video and what u do ,fantastic.
Could be. A little palladium in the electrolyte isn’t bad. But if it gets too much palladium in there then the palladium could co-deposit with the silver. But contaminated silver is not the main concern. Palladium is about 38 times more valuable than silver.
I wonder if there would be a way to recapture the gas in aqueous solution to recover nitric acid and reduce over cost of production. You would need a closed reactor but with you melting 100k bars I’m sure you could afford it 😃
I’ve looked into large glass reactors with ground glass covers and fittings. It was pricey, I could afford one. But I’m afraid I’d end up never using it.
Step 1: Alloy gold with silver (and other base metals) Step 2: Use nitric acid to remove silver (and other base metals) from the gold Honest question, what does this achieve?
I know it sounds counter intuitive. Adding silver lowers gold concentration so that the nitric can pull the silver and base metals. The karat gold is an alloy of gold, silver, copper and zinc. All that non-gold metal gets pulled too. So the resulting gold after the nitric boils is close to three nines. If I tried to boil the 14k gold without adding additional sterling silver, then nothing would happen. The nitric cant penetrate 14k gold.
@@sreetips Thanks for taking the time to reply. It is quite counter intuitive, my layman brain is just thinking "it can't purify something that is 70% gold up to ~100% but it *can* purify something that's 15% gold up to ~100%" I would love to understand chemistry like you and some other youtubers do, to the uninitiated it's like magical transmutation. Is your main business in precious metal refining and reclamation or do you just do it as a side gig?

If its corrosion than you can apply a conformal coating to protect against the acid fumes. I've used clear enamel paint or silicone conformal spray. I've used this method to protect my psu and vent fan. Never replaced either of them once they were protected. I had gone through several fans and a PSU over a 3 year period. It's been over 5 years now without any problems :-)
Great, could you explain the process of growing the silver crystals please?
Yes, I refine gold. I use sterling silver, that I buy at estate sales, to refine the scrap gold. I recover the silver from that, melt into shot, and run it through my silver cell. The cell converts the impure silver (about 980 parts per thousand silver) to high purity four nines fine (9999 parts per ten thousand) pure elemental silver metal. The impure silver is added to the anode basket. The anode basket is suspended in the silver nitrate electrolyte. I pass an electric current through the impure silver. The silver dissolves, passes through the Dacron filter, travels through the silver nitrate electrolyte, and deposits on the stainless steel bowl (the cathode). The bowl is connected to the negative pole of the power supply. The process only deposits pure silver on the cathode. So I’m refining the impure silver, into high purity silver. When it’s full, I harvest the pure silver crystal, put it away and forget about it. Then I repeat the whole thing again.
Wonder how much it would produce if ya ran a taller bowl use a nice stew pot maybe I know they make a good stainless one I have one them ud just have to make a bigger basket ya hold the silver in and make it a hair longer maybe that way u could use the entire filter instead of cutting off half of it then u could make 2x as much silver
There’s a critical distance of 4 to 4.5 inches that must be maintained between the anode basket and the cathode. I did get a larger stainless bowl to experiment with.
Would it be possible to inquart using the cemented silver from the last gold refining and keep circling the same silver? I seem to remember you saying this impure silver is still more pure than Sterling.
Yes, but it’s not recommended. Gold contains platinum group metals, especially white gold. Using cement silver, over and over, would cause PGMs to build up in the cement silver because the PGMs tend to follow the silver. So that when you tried to run it through the silver cell, those PGMs (especially palladium) could get into the electrolyte and cause problems.
@@sreetips I see. Thanks for the information.
Something I always wondered, is there a way to predict the purity of a refining? For example, you said this was probably like 3 "9s". Had you refined it again; I know it would have been a higher purity...but would it have been like 4 "9s" only? How many refinings does it usually take you to get to 5 "9s?"
To get to 5 nines, you will have to do an electrolytic (gold) cell.
You can tell much about the purity of the gold by how it looks after pouring. This ingot was questionable, no telling what the purity is without xrf. It don’t take much to throw the purity off.
This video has to be one of them top 10 satisfying videos🤩🤩
always great videos, best chemistry class, vert good guitar background.
amazing video.... you really are a master...are there any toxic fumes from doing the silver cell?
Not if we get all the nitric out first
Amazing work my friend
Would the .999 fine gold have microscopic holes throughout? Before melting?
Yes
Love your videos. Thank you Sir, very informative
$6366 worth of gold but that is not all you got. I would love a start to finish to find out how much silver and copper comes from the same batch of gold. Any chance you have or will do a complete start to finish just to show us all the metals recovered and purified?
Have u ever taken the gold field or plated stuff and melted it down into shot and then tried to do the recovery off that or is the other metal in it make it nor easy to do or something of tbat nature I'm just curious on that part
In order for electrolytic refining to be successful, the anode material must be relatively high purity.
Boring news on tv screen..crap and war.. its' what i mean..find some popcorn..a bag of chips..now is showtime..thank you Sreetips 😂🔥
9:45 the secret sauce!
Sreetips just curious. Does it concern you any pouring nitric wearing nitrile gloves?
No
@@sreetips gloves are definitely important. It's outside of what you normally film but it would be interesting to see the sreetips rundown on nitrile combustion.
Nitrile gloves will burst into flames (according to one video) with 95% fuming nitric acid. I use 70% nitric and nitrile gloves are completely safe.
The majestic golden toad 😂 lovin ya videos but theyre great and informative. Your methods make wanna pick up doing silver refining
I want to make one of these so dang bad but i dont really have a place to set it up nor one of those power supplys or a good collection of silver to feed it.... Hopefully one day in the future I'll be able to make one
When you pour your inquarted gold into the water, why not use the wooden board system that you use for the silver shot to get smaller shot size thus more surface area? Or does it really matter?
It doesn’t matter, plus the lazy gets the best of me.
Excellent video thank you 😊
Wish I had your talent. I have some family gold I’d love refined down to a bar.
Silver comes from the dance and final collapse of neutron stars. Oh, and your wife buys it too. LOL Great video!
That's where gold comes from too so you/we owe quite a bit to neutron stars.
The power supply doesn't have enough capacity to run 2 cells in a series?
I think he tried that a few years ago, didn’t work.
It’s better to have two independent cells.
He is doubling his production of silver for the same timeframe.
Hopefully one day he’ll have many independent cells producing silver.
😊😊😊
@@camus6208 By that time it will be a full time job, not what he is looking for.
Probably but one cell will rob the other and it doesn’t work well. Best to run each cell with its own power supply.
Nice jammin dude!
Can u run both silver cells on one power pac or not,can u please let us know when u do the next video on the silver cells please. Love your video and what u do ,fantastic.
No, each cell needs its own power supply. If I try two on one power supply, one of the cells will try to hog the power from the other.
Thanks for letting us know that .
Is it absolutly necessary to cement sthe silver or could we just make shot by melting sterling silver and use that in the cell?
Not recommended. The amount of copper in sterling silver would quickly saturate the electrolyte with copper.
My silver cell electrolyte is turning green! Is that paladium?
Šis, is nicel.
Could be. A little palladium in the electrolyte isn’t bad. But if it gets too much palladium in there then the palladium could co-deposit with the silver. But contaminated silver is not the main concern. Palladium is about 38 times more valuable than silver.
What happens to the silver that runs out of charge does it make it less conductable
I don’t know if I’ve ever had silver run out of charge.
I wanna see the crystal of sliver. You way smarter then I ever thought of being. This video is way over my head.
I wonder if there would be a way to recapture the gas in aqueous solution to recover nitric acid and reduce over cost of production. You would need a closed reactor but with you melting 100k bars I’m sure you could afford it 😃
I’ve looked into large glass reactors with ground glass covers and fittings. It was pricey, I could afford one. But I’m afraid I’d end up never using it.
Step 1: Alloy gold with silver (and other base metals)
Step 2: Use nitric acid to remove silver (and other base metals) from the gold
Honest question, what does this achieve?
I know it sounds counter intuitive. Adding silver lowers gold concentration so that the nitric can pull the silver and base metals. The karat gold is an alloy of gold, silver, copper and zinc. All that non-gold metal gets pulled too. So the resulting gold after the nitric boils is close to three nines. If I tried to boil the 14k gold without adding additional sterling silver, then nothing would happen. The nitric cant penetrate 14k gold.
@@sreetips Thanks for taking the time to reply. It is quite counter intuitive, my layman brain is just thinking "it can't purify something that is 70% gold up to ~100% but it *can* purify something that's 15% gold up to ~100%"
I would love to understand chemistry like you and some other youtubers do, to the uninitiated it's like magical transmutation.
Is your main business in precious metal refining and reclamation or do you just do it as a side gig?
Refining is my hobby. I do it for fun. It’s not my business. My business, I guess you could say, is making video content for my UA-cam channel.
you have copper crystal forming next to the edge to the right it's blue
