Thank you for this video. I'm studying silver refining in the Bible so this a great visual. I imagine this is how it was done or similar to the process mentioned in the Scriptures. Other videos are available with modern methods but this is much better for my lesson.

Thank you for this video!!! I looked it up to help me understand Psalm 12!! Wow! Powerful!!

[@ProfaneGod]

Try heating the muriatic acid to boiling to make it more effective to get the iron out better its a refining technique used by chemical refiners.

[@BRP42]

My exact thought!

[@matthiaskidd439]

Why waste the time with HCl when you can use HNO3 (Nitric acid) it will disolve the Silver and other impurities which you can the use the reaction series to reduce the silvdr as a nice .999 silver.

[@ProfaneGod]

@@matthiaskidd439 because he wants to get the iron out in as few steps as possible and nitric will also dissolve the iron meaning another step to get the silver out.

[@ssteele1812]

Not to mention that Nitric costs about 4 times as much and is harder to source than going down to the local hardware store.

[@matthiaskidd439]

@@ProfaneGod if you use copper to reduce the silver from a Silver Nitrate Solution you wont need to worry about the Iron. It will stay in the Solution because of the Reaction Series, you can then use Iron to reduce out the Copper should you wish to do that and then it's easier to refine the Nitric acid Solution to be able to re-use it again

I believe that film is now considered an ancient technology, too.

I saw those small silver beads and I saw them coming together making bigger silver beads nice

[@GeoffBosco]

That one shot of your propane/air setup told me more about how to build a propane furnace than the thousands of "DIY furnace" builds here on youtube that either show them using an expensive premade propane nozzle or a convoluted complex process to build their own. Thank you.

Ya I think the Basel three or something calls for new laws or revaluation of gold and is going to force the paper gold market to change. It’s good cause now gold is consider tier one money again.

[@koltoncrane3099]

He had like 750 grams of silver at the end. That’s way more then 50 or 30 bucks. You have to convert grams to ounces and then times it by the price of the metal.

[@danielparsons5519]

Interesting steps. I would prefer Nitric acid after silver shot with heat. Yes Nitric costs but you can easily make your own. Thing is after all metals are dissolved you just precipitate with copper and the Silver nitrate and copper trade places and your left with near pure elemental silver powder while copper is in solution. But I do love your process you just showed as well. Great job👍

Having several hundred pounds of those silver ion exchangers left by my dad. He never quite solved the proses of getting the silver out of them without burning up the crucibles. He burned quite a few up. Going to give your proses a try and hope to get enough to buy more crucibles to get all the silver out of them. Hope to get over 1000oz. Now if I can find a easy way to clean up the bleach fixer silver bars we have.... You are my first subscribed channel. Thanks for the information.

[@MrAllan9]

Been enjoying the vids for quite some time then realized I wasn't subbed, I am now.

[@CaptainRadack]

It would have been really cool if you did it like they did it 2000 years ago with what they used to contain the metal, the type of fire and bellows, you know make it real like they did it back then.

[@pixelpatter01]

The take away here is to not use iron as your reducing agent when precipitating out dissolved silver. Use scrap copper wire instead.

[@Alondro77]

I found that the warm dilute nitric acid (50% concentrated nitric with 50% water) works well, then adding concentrated sodium chloride works fantastically. Wash the chloride 3 times in distilled water to remove all dissolved base metals. Save the acid solution for neutralizing with the base leftover from later steps. If it's blue, then there's a lot of copper you can recover easily with a clean piece of iron. Then add double the volume of the white silver chloride precipitate of sodium hydroxide and heat under a thin layer of water to about 60-70C overnight, stirring with a plastic rod every hour or two. That converts the chloride quite well to silver oxide. Then dump the excess solution into the acid waste. Lots of black stuff will form (mostly iron hydroxide if you did copper recovery using iron). After washing twice with distilled water, you can reduce the silver oxide with either drying and smelting with carbon, or just dumping a bunch of corn syrup or plain table sugar into the wet goop (make sure there's enough clean water to cover it. The reaction works better when the sugar can dissolve.) I've done two little batches that way and ended up with two ounces of very pure silver, over 99.5%.

[@BeefZupreme]

[@knockhello2604]

[@jason101386]

this is simple. i like this video

[@SquareCoinTalk]

Thank you Jason as always very interesting

[@pdriot9424]

Awesome video!

[@roywhipple4923]

Using sulfuric acid and water is the best way to get the iron out , it dissolves all base metals except for lead, and the iron and water react well enough with sulfuric acid that you will need a heat resistant bucket, but all you would have left is lead silver and any gold.

[@dejanmiletic239]

[@joshp6061]

Didn’t do an XRF scan to check the silver? I’m wondering how much iron was left in it

[@GeoffBosco]

@@reverendtfg6802 That's fewer irons than I expected

[@1616katerst]

Put a piece of cardboard on the bricks you set the crucible on coming out of the furnace. Yes it will burn and smoke instantly but only a few seconds. The bricks won’t stick to bottom of crucible and saves tear outs on the bottom or trying to kick the bricks off or not even getting them off for the next melt.

[@getprobed838]

you could use a soray bottle with water and mist the outside if the cement bowl to make it harden a bit incase the flames want to blow the cement everywhere

[@BeefZupreme]

That is such a beautiful piece!

[@Jelleasy]

cool stuff thanks for sharing

[@johnh9748]

With the acid, agitating will help remove more iron. as the acid dissolves the iron, it forms a layer of spent acid on the surface. That spent acid is no longer reactive. Agitating the mixture will constantly expose fresh, unspent acid to the surface.

[@MichaelClark-uw7ex]

That weird iron/lead stuff looks like the alloy they make pipe organ tubes out of. It has that visible surface crystal structure. Which stands to reason, organ pipe metal a lead alloy to reduce resonance.

[@kenchappelle816]

I have a mineral claim with a lot of silver in with the free mill gold how do I recover the silver ?

[@paulcoover9197]

You heat the muratic acid. They clean crystals that way.

[@rogerclaiborne6815]

Might want to use the acid wash first to remove iron before attempting to smelt in furnace. The silver plated and mixed iron would be much easier to remove before you melted it into an alloy.

[@rogerclaiborne6815]

I think dilute sulfuric acid might be better at getting more iron wool residue out of the silver than muratic as well.

[@pneumatic00]

@@rogerclaiborne6815 Agree, sulfuric.

[@knockhello2604]

How do you guys know this shit lol

[@BigSargeH]

Suggestion I know it's way late but silver bonds to Zn something like 300x more to Zn lead then Floats to surface like slag. Then remelt and separate the Zn floating on top the molten siver

[@mandyp2320]

To your questions at 24 minutes about the lead. That’s galena, it’s just lead in a high purity. I could be wrong but it looks just like galena.
