Yes

Eccentric, but yes.

@@nikolajwinther5955 Look at 26:17 - they are near perfectly circular and share the same centre point with different radii so concentric. That's why it looks just stunning. Agreed, the eccentricity of the outer ellipses are of course < 1 hence eccentric.

​@@AndyGraceMedia I didn't even know that's where the word eccentric came from, every day is a school day! Lol

Much agreed..

Nice!

You are wise to hang on to the gold and don’t trade it for declining paper dollars

Thank you

Recycle it, man the gold is still there. That's the beauty of chemistry. If you didn't incinerate the gold ,literally burned it away, it should be in the material you have left.

Dont buy the Ebay bars lol, they are a scam. Your failed cpu attempt is salvagable as long as u kept the acid. Check out the 'stock pot' series on this channel on how to cement out valuables from the acid waste.

@@osmia3561 I’ll check it out! Thanks! I have a Gallon of acid, with gold and silver contents. And about another gallon of gold flakes flaking off a Muriatic peroxide solution. Been frustrating at times but extremely cool!

@@jimwednt1229 I’m gonna try! It can get frustrating! More attempts coming soon!

Those have gold, but the amount is tiny. Stannous tests are not optional. Get some and use it to verify gold in solution.

Thank you! I had a terrible speech impediment as a child. Still working to overcome it.

@@sreetips what happens to the silver that you dump all the excess water in.

Agree😊. Have a nice day.

That’s what I’m talking about. Just wait until people realize that all their valuations are based on a mountain of debt. Then we won’t be able to find gold anywhere. When? Who knows? But it’s coming,

Every now and then I lite the mold torch a little too late and the bar forms ugly.

​@sreetips is there such thing as heating the mold too early ? Or is a general rule you go by for time ?

I begin heating the mold as I begin the melt and it seems to work fine. A graphite mold can be overheated and the graphite will become deteriorated.

Preheating the mold is key.

Welcome!

The chance of lead being in the scrap is very low because lead is not normally used in gold jewelry. The only way is if someone, who didn’t know any better, used lead solder to do a repair. Doesn’t matter, I add the sulfuric just in case. I’ve never seen lead precipitate either. But the sulfuric hurts nothing, costs almost nothing, and provides a big benefit. Lead, even in trace amounts, ruins the ductility and malleability of gold. Better to add it, even if the presence of lead is not suspected, rather than not add it and risk getting a trace of lead in the gold.

No, that was once through the grinder. A second refining would have removed that little bit of surface discoloration.

1) The nitric is still able to dissolve silver. I can tell because of the red fumes it evolves when added to the silver in my silver jar. 2) that nitric will have some silver in it. I’m trying to remove the silver so it’s best to use fresh nitric to make the aqua regia.

Yes, I have a couple videos of it on my channel. Just type “wohlwill” into the search block on my channel.

Hello, unfortunately I only refine my own material. This is my hobby.

I would gladly watch (or sleep) through an hour long video! It may take me about 8 attempts to watch one, but I will do it!

Welcome and thank you!

Yes

Getting the mold real hot is key to getting a good shape on the bar.

I started on the goldrefiningforum.com my user name there is kadriver.

@@sreetips Awesome and thank you. Now let's see what I can get into. Thank you again.

Yes

im watching your silver cell video now lol, thanks!

The intense heat would quickly destroy the mold.

@@sreetips i meant like a metal mold like kind you pour into, but only a single ingot mold with a cap plate.

I’d be concerned about getting it too hot and the gold welding to the metal.

The copper is highly contaminated with other metals after cementing out on iron. So it gets tossed. The iron solution gets dropped with sodium hydroxide. The solids (metal hydroxides) get filtered out, dried to a moist cake and disposed of. The caustic solution gets brought to pH7 with pH swimming pool decreaser and disposed of down the drain. Nothing toxic or acidic gets dumped into the waste stream,

@@sreetips Thank you for taking the time to explain 👍

Palladium is soluble in hot nitric. But don’t expect a clean separation. Some of the platinum will dissolve along with the palladium. Some of the palladium will remain in the platinum. SMB is selective for gold, but traces of PGMs will come down with the gold if they are present.

Yes

Three times the amount of Ag in the alloy reduces Au to o.25%. A quarter. Inquartation... 😉✌️

I want an alloy that is 1 part pure gold and three parts silver.
