The honor is mine Chris! I love those Native American rounds... that die is amazing. It really hurt to blunder like I did lol. Thanks for taking the time to watch the vid!!
Thanks for watching Derek! As long as they were happy in the end... that's all that really matters to me! But that wasn't very comforting at the time lol
These videos are amazingly instructive and relaxing as well, thank you! 2 quick questions - 1. When do you decide whether to use sulphuric or not as part of refining? I noticed it wasn't part of this refining. 2. What's the benefit of a stannous test after dissolving the pure gold in aqua regia? I can see why you need it after the SMB step, but If it comes back negative in aqua regio, where are you left? Where else could it be?
I just got into these refining videos. Started with Sreetips. Super knowledgeable. Now I’ve come across you. Perfectionist or OCD? Lol beautiful work, Jeff! Hope I can buy some of your art one day, but until then, I’m about to go binge all your videos. Lol
The first time, I had over 10oz of gold in solution I suddenly found myself a bit panicky when my mind wandered to the thought of the beaker breaking. "What am I doing?!"... 😆
@@LithicMetals I’d be afraid of it ending up the most expensive carpet stain in history. I suppose with enough chemistry and ingenuity you could always get it back but I can’t imagine trying to refine your carpet, padding, subfloor and drywall to get your gold back.
10:00 Hello. Thanks for the video, very interesting. I have a question. I noticed that you don't neutralize the nitric acid before adding SMB. How does SMB precipitate gold if there are acids, aqua regia? 😊Thanks in advance🙂
Hi! I'm generally very careful to only add just enough nitric to get the job done. Then to make sure, I usually evaporate the AR down a bit to burn any excess free nitrates off. Then rehydrate.
Amonia rinse? Never heard about, what is it good for? Understand HCl, water, I have seen H2SO4 boils, but not amonia. Just curious question.... could form amonium chloride... but why? Surprising was the collor of the second refining liquid. looked the same as the first pass. Isnt some colloidal gold still in it? does not show on SnCl2 test. No idea, how to get it, to be honest. Or some junk from tap water? Here we have iron, mangan an all kind of minerals as my town is known for mineral water... And that was some very impressive gold powder... Great looking gold... Greetings from the Heart of Europe
In short, the ammonia cleans the precipitated gold extremely well. Scrubs the remaining traces of solution off of the precipitate. I use filtered tap water mostly for diluting the AR. After that I generally go back to distilled.
@@LithicMetals Thank you for answers. I "know everything" in theory, but the reality has something in sleave for me for sure... Always has... Like goldwashing, gold does not care about theory of water pressure, is on strange places... 🌟⛏❤
So when you use the spray bottle to break the surface tension and/or wash particles down the sides of the beaker. Is it just water? what's in the spray bottle?
Glad you enjoy them. I'm not sure what you are referring to in regards to "measurements"... if you mean what size bars I pour, it's currently 1/2oz, 1oz, 2oz, 5oz, and 10oz gold bars. I process the waste solutions in batches. I drop all the copper and traces of precious metals with iron. Then, adjust the ph until it is rendered inert. Then, it can be safely disposed of. Thanks for watching! 😁
@@LithicMetals do you get a decent yield? I watched sreetips videos when I had COVID and it seemed like a lot of work for a little bit of metal. Interesting nonetheless. Sorry for all the questions but What’s your background? Is refining your full time job? I thought you were maybe a chemist or a jeweler. I like your videos

You're attention to detail is second to none. Even down to the packaging. You do an awesome job. Thank you for sharing
Thanks so much Chris! 😁
I’m honored to own 3 of your pieces Jeff ,the 1/2 oz native piece might be my favorite , great video
The honor is mine Chris! I love those Native American rounds... that die is amazing. It really hurt to blunder like I did lol. Thanks for taking the time to watch the vid!!
*Lithic Metals* Bravo well done, thank-you for taking the time to bring us along. God Bless.
Thanks for watching!
That was awesome! I bet if the customer knew you had pour the native American 1/2 ozt round, they woulda kept it!!
Thanks for sharing Jeff!!

Simply amazing and beautiful. 🤩 👍😁

same started with sreetips
I want to get to this level of precision, from beginning to end
I appreciate you Gerardus!
Thanks for the upload. It really must have hurt to melt that .5oz coin it looked perfect. I look forward to your next upload.
It really sucked! A bit of a heart breaker lol. Thanks for watching John!
another awesome video jeff
Thanks Pete!
The first time you dissolve a few thousand dollars worth of shiny gold into solution must be terrifying.

Is a fascinated newbie, I am wondering how you decide to add silver before refining or go straight to aqua regia?

Yes, just distilled water.
Can not wait to send my stuff
I find these videos fascinating. My only question is what are the measurements that you pour?
Also, how do you dispose of the waste as I would imagine it’s highly corrosive, so you can’t just pour it down the drain.

I can watch this every day
😁
_Very good_ 👌🏾👍🏾
Thank you! 😁
By which acid you wash gold dust?
Perfect just perfect 👍
What exactly is the little taps you give the mold when you pour a bar for? Does it have something to do with the pour lines??
Ripples the liquid gold as it cools make a nice pattern
Is the hydracloric acid dilute, or straight from the bottle
Straight from the bottle 😁
What’s the powder your dropping in to drop the gold,, dude this fantastic stuff.
I think you mean the SMB, (sodium-metabisulfite) 😁
Hi, is a Smb have expiry date ?
I don't believe so. If it does, it's a very long time
Have you done a eWaste recovery where you pull both the gold and silver from the scrap?
I don't process e-waste other than an experiment now and again. There's just not much there to recover.
Do you refine your waste rinses and what not for platinum group metals?
On occasion, yes.
@@LithicMetals do you get a decent yield? I watched sreetips videos when I had COVID and it seemed like a lot of work for a little bit of metal. Interesting nonetheless.

سلام استاد
استاد درصد دو اسید نیتریک وکلرید ریک اکولوژیا رو لطف میکنید متشکرم .
One looks gold... The other looks like buttered popcorn.
To which company does that gold refining glass belong? I use borosil glass for this purpose.
I'm pretty sure most quality beakers are made with Boro 3.3
Enjoyed
Why doesn't the acid eat into the beaker itself?
Great video. When it’s great content, length of video means nothing.
I appreciate that, thanks! 😁
What is "E scrap"?
Electronic waste, from computers and such.
And your production leaves the others in your wake!
😮
is it like making pancakes, the first one doent always turn out the best?
Platinum group metals cause the reddish hue
Does your mom know you have her Corning ware??😜
I have a way better collection than she does lol
