How to extract Silver from a Coin (or other silver containing material)

  • Published on Nov 3, 2014
  • In this video I show you how to extract silver from a coin or other metallic material. The coin that I used is 50% copper and 50% silver.
    I loosely followed the procedure from here:

    Since you added an excess of copper, isn't there quite a bit of copper left in the silver powder????

    Hi. I want to make silver and i got tons of pennies and nickles but you need to tell me where to get a bucket of nitrous acid at. And does it cost alot? Does the hardware place have it?

    So you dissolve silver is blue so why some video is white ??

    You said that you used a silver quarter, and that you lost 10% in the process. Are you sure that it was lost in the reaction? US Silver coins were "only" 90% silver, with other less precious metals filling out the rest to ensure durability. So - going by the data provided - I can't help but feel that you did in fact get the silver, and the 10% of the original mass you lost was those non-precious metals.
    Could we someday maybe get a followup or redo video? Only with solid numbers of the mass of the coin, the expected silver amount, and what was produced at the end?

    Can you purchase the chemicals over the counter? How do you measure/estimate 1 troy ounce of product? How do you know the purity? Great video. Thats for sharing.

      Yeah. I got tons of pennies and nickles and dimes and i just need to get some nitrous acid. Like a bucket of it would be good.

    So if the coin is 90 percent silver u get 92.5 Sterling out off it ?

  • Dom1118

    From one 90% quarter? Looks roughly about the right amount of .999 by the end.

    I have 2M Nitric Acid solution, however I only obtained silver nitrate with heavy heating of the reaction vessel. Is this becuase I am using a solution of nitric acid and not concentrated?

    That was cool! Can u do a US coin next like a 50c peice or dollar coin? Pre 65 is silver. I know it's the same as what you just did but it would be cool to see

    First I will add 20 ml of water
    Me: ok maybe I can try.
    Then I will add 20ml of CONCENTRATED NITRIC ACID
    Me: ok that idea was immediately shut down...

    Would be interested to see you do a video on the properties and uses of colloidal silver. All I know is it's sold by snake-oil merchants, and turns gullible people's skin blue.

    • Thomas Jensen

      There is very little silver in colloidal silver....and you have to take WAY more than recommended to turn your skin greyish blue. And colloidal silver is sold just about everywhere now. Silver is antimicrobial, antifungal, and antiviral.

    Could this process be used to determine nickel content in a coin?

    • Maggie P
      Maggie P Year ago +1

      You'd have to find a way to isolate the nickel, but once you do that, you can weigh it, and compare the weight to that of the original coin.
      This should give you a good idea of %.

    After the first silver extraction, add salt or hydrochloric acid to precipitate AgCl. Filter. To the AgCl, add NaOH in crucible and fire. Then add carbon powder and fire again to get silver metal missed in the 1st extraction. Some borax will help coalesce the silver. Dump while molten as you did first and wash in water to dissolve the borax & salt.

    I use fire torch just like you, but the silver didn't melt
    Any tips ?? Thanks

    Wouldn't HCl also work to separate silver from other metals and leave you with almost pure silver chloride which you can then add sodium hydroxide and dextrose to to convert silver chloride into fine particles of silver metal? I have also seen copper being used to form silver on the surface which then falls off.

    I know this is ages after the video was posted, but could you have increased your yield by letting the copper wire react with the solution in a flask with a stir rod to smash up the precipitated silver and remaining copper? Love your videos, just found this channel recently and I'm going through a bunch of your older material, still great stuff!

    Coins almost always worth more as currency than the metals they're made out of. Otherwise nobody would use them as currency, they'd just extract the more valuable metals and sell or trade them, instead. This is why nations don't use gold coins any more - the gold was worth more by weight than the coins were supposed to be worth!

    You can also drop the silver with iodized salt wich will then turn it into silver chloride(looks like cottage cheese) and then get rid of the water and add in a 1to 20 part mix of 1(hydrochloric acid) and 20(DI water) into a flat dish and add zink powder until there is no white(silver chloride) left and then you let it sit over night and you will then have pure silver with no zink or copper contaminants and it should look just like cement
    Look for bubbles before you dry it out and if so let it sit until it stops...

    Great presentation. Thank you so much for this.
    Question: US War Nickels minted from 1942 - 1945 were 35% Silver, 9% Manganese and 56% Nickel. Would this technique work on that metal combination? I have heard that refiners pass over the war nickels because the melt temperatures of the Silver and other metal(s) are too close, also that the manganese is extremely hazardous, toxic.

    putting borax in the crucible will prevent the silver from sticking to it
