Some Questions and answers:
-Why use such a small container? =Because the larger the container the more solution of silver nitrate is required, which means that more of your silver is trapped in there.
-What are those small spots on your skin? =As you can imagine, it is due to silver nitrate splashes that landed on it. It is not so tragic, I tell everyone that I refilled a printer ink cartridge.
-Dude, how can you know that the silver content is 70% ? =Well, I know what went into that jar, that's why.
-Could you build a much better power supply? Theoretically I could, out of two transformers. But I have not found the right types yet. Actually anything that can supply (DC current) a voltage between 1,5 and 3,5 V and lots of Amps (goes anywhere from 10A to 800A) is suited for the job. Plating rectifiers do the job, but they cost a lot.
-Didn't your @1,5V time lapse take too long for producing almost nothing? =The batteries were already a bit consumed, I didn't measure it but I guess the current was much smaller than 0,28A. Theoretically each battery can supply at least 2000mAh which means that each battery can plate out 8,048g of pure silver.
-70% of 25g makes 17,5g, you only got 16,9g of fine silver, where is the rest of it? =The rest of the silver is in the first solution where I left the copper tube in, a small part is in the electrolyte solution because it had a bit of free nitric acid.
-Where do I get nitric acid from? =Good question, depends where on this planet you live at. In some countries you cannot buy nitric acid but you might get it through friends who work at a synthesis plant. In others, like Germany, you go to the pharmacy and buy some. Either way, you still have the option to make your own, I recommend watching Nurdrage's videos on how to make some.
-Why not edit the song so it won't need repeating itself? =Since I do not own the song I guess it is fair to at least not modify it, with respect to the artist.

Thank you this saves a lot of time converting silver chloride to silver metal this is one of the most useful videos on utube

My compliments.... this is the BEST ( easy and working ) Silver refinery movie ever! :-) Did it the same way with some silver coins.... about 25 gram of silver :-)

You are the Macgaiver of the silver world!

@metaltect basically you leave it to dry out. once dry it can be removed, only almost completely. there will always be a small bit left thus one does not throw away the filter. keep the filter paper and burn it with the torch, or burn more of them as they accumulate. the paper burns to ash and what is left over is mostly precious metal, it can be redissolved in nitric acid and put back into the cycle.

Awesome work. Very informative. Thanks for taking the time to produce this video and share with us.

Thanks. I dissolved around 750-800 gram of various silver in Nitric Acid and distilled water. Am not totally done, as i was waiting for some copper who came yesterday. But have some who I have just to clean, when the vacuum pump arrives. And then melting some larger ingots with a silver stick in so I can easy hock up my + in the set-up. And rest I will make cornflakes of and add to the basket easy for faster dissolving :) And now I will order some 999 silver to add to the 999 I got to get enough to make the Silver Nitrate bath :) Will update you later on. Thanks for helping out! Kent

That was the best video on silver refining. Thank you.

@doinen silver nitrate is a white salt, silver nitrate solution is colorless. the bluish thing is the copper nitrate, which is unwanted. yes, you can store the solution, in glass jars for example.
-
@27simber yes you can use sterling as a substitute for the fine silver. though you can make high purity silver by melting some of the cemented silver you get at 0:45
-
Your a legend for showing this! I'm in the GRF too, but what you've presented is an incredibly practical small method for silver cell - I made one very similar and worked great. Finished with 12.665 grams 99.9% silver. This makes the most beautiful bars when cast, and leaves not a trace of oxides in the melting dish. To answer the q's below, I reuse my copper tube as its very difficult to get all traces of silver off it, so I use it again and it'll fall off when more silver builds up.

That was amazing !
-
That's really excellent. Looks like the silver from the melt was pretty pure to start with as the surface crazed when it cooled down.
-
That is awesome! thanks for sharing
-
Very cool, nice job!
-
This is all in one .. super easy and self explanatory thx for uploading :)
-
@27simber you can make silver nitrate from sterling, but it will be impure because of the copper nitrate. you can make a better quality silver nitrate by dissolving some cemented silver in nitric acid.
-
@bigcoolviking 2. all other alloying metals that can be attacked by the acid will go into the aqueous solution. at 0:50 you can see that all the metals above copper will stay in solution in their nitric salt form, whereas all metals below copper will get cemented out in a metallic form. so, to cut it short, the 30% copper from the alloy is the blue water you see in the jar.

@Silversmyth thanks for commenting. you might find the improvised liver of sulphur interesting as well

@RenkoTrader since you are new, i advise you to be more specific on your inquiries like: when you heat the silver at 1:59 i did not heat any silver nitrate, all that is being heated, actually melted, is metallic silver. if you heat silver nitrate you may end up with molten silver nitrate but most often this salt decomposes so it is not advisable to do such a thing.
