Silver Cell Anode Filters Part 3

[@nonshock]

I cannot wait for you to do a series on your sleeves and see how much precious metals you can get out of them.

[@ut000bs]

Sorry. That shirt is destined for the Smithsonian.

[@ChrisHopkinsBass]

KZbin takes the precious metals out of those sleeves and turns them into subscriber plaques

[@rockosgaminglogic]

@@ChrisHopkinsBass subscriber plaques are plastic garbage made in china, so its probably toxic too.

Best comment 😂

[@William_Borgeson]

They say in nature nothing is wasted, that's why I love what you do. Everything that you do seems to be a closed-loop system, you minimize waste, expenditures, etc. It's a fantastic way to work, and I learn so much just by watching. Thank you.

[@jayson8372]

Thank you again for taking the time to show us how you process metals, it is a interesting process for sure.

Gooood afternoon from central Florida! Hope everyone has a great afternoon!

Goooood afternoon

[@base_cannon6066]

Great video and thank you for the series, Sreetips!

Good evening Sreetips, Interesting processes trying to produce a clean final product. If we don't try. We don't learn. Fun stuff bud.

[@gfhrtshergheghegewgewgew1730]

what goes really unsung is all the work you put in editing these videos together and recording narration for them, it makes them very easily watchable

[@jeepin4on4]

Thanks for sharing, I can watch your videos all day every day.

[@saiko3902]

Thanks sree. For sharing and teaching as you go. You have the best precious recovery method and teaching skills for gens to come.

This is awesome so far I can't wait to see the final talle thanks for sharing this six stars

[@ArielleViking]

Great series and nice separation of the platinum group metals. 👍

[@IIIKNOW3]

So, great video series!! I have a question though, when you had the silver+Pd+trace Pt would it work to add HCl to get the silver out as chloride before adding the DMG?

[@sreetips]

Possibly

[@soapsNjncojeans96]

Absolutely incredible!!

[@AndyGraceMedia]

Excellent. The question will be how much more Pd is in this recovery compared with what was in the little button you had analysed at the big refiner at about 25% or about 1.8 grams. You should have been paid more for that!

[@sreetips]

That’s how they can afford to pay 98% for you gold.

[@theallseeingmaster]

@@sreetips Fair trade; that seems to be a very fair price for gold though I wouldn't know.

[@richardmccann4815]

They will always try to screw you on the most valuable metal!

[@jonballard4453]

Sreetips, I've seen you add sulfuric acid to precipitate out any lead on pretty much every video you've ever done but I've yet to see any lead actually precipitate out is there any way that you might be able to show what that would look like and or give some examples of when that might occur?thank you so much for all of your videos they are extremely helpful informative and enjoyable

[@sreetips]

Sometimes, someone, will try to use soft lead solder to repair a piece of jewelry. It could be in a location that’s not easy to spot during sorting. Lead, even in just trace amounts, will ruin the ductility (ability to stretch) and malleability (ability to hammer into sheets). Adding a few drops of sulfuric is a technique that I learned from Harold_V on the goldrefiningforum.com He says it hurts nothing, costs almost nothing, and provides a big benefit. I’ve never seen what it looks like in the filter either. So next time I’ll add some lead and see if we can detect it during filtering.

[@diegohenrique3388]

now you can understand in the previous video about DMG precipitating silver

[@mikew8214]

PGMs seem like too much of a pain for hobbyists. I enjoy watching you work on this stuff though!

[@ottolehikoinen6193]

Well I've heard some jewellers sometimes use a PGM alloy on their jewellery so it's pretty tough for professionals too. For example the latest PGM-button might go straight to the working table of a jeweller. They will tell you of course it's not pure.

[@Chewyfood]

Any plans on doing a harvest from the clothing you use to do refining? Looks like there have been a lot of spills over the years! Haha.

[@reverendtfg6802]

*I'm waiting for the day when Mr. Sreetips processes that green shirt for precious metals.*

[@raheelahdar1741]

very good Sir... What is this DMG i couldn't understand it...plz i need to know dgm

[@sreetips]

DMG = dimethylgloyxime

[@raheelahdar1741]

thank you dear Sir ❤️

[@Joe.Rogan.]

Any update on the solids.. still filtering I guess?

[@sreetips]

Over four days now. I’ll address it in part four.

[@adambuysyuckyhouses]

I got a dumb suggestion. When u cement out the copper out of your solution. Melt it. Then use it in your stock pot. It prolly contains a small amount of gold too. Free copper except needs to be melted.

[@sreetips]

It’s heavily contaminated. Clean copper for refining is cheap and plentiful. After that, it becomes waste.

[@adambuysyuckyhouses]

@@sreetips makes sense

[@LincolnTank-StillOnTheSprue]

Love watching your vids. I wonder if, perhaps, you might do one in which you demonstrate how you make residual liquids from your processes inert and/or how you safely dispose of them. As a non-Chemist I would find this very interesting

[@sreetips]

Waste treatment.

[@sreetips]

In progress.

[@dirkschippers2957]

Just what I wanted to hear!@@sreetips

[@hobbiesrus]

Thank you for the update! What does the trusty metals bible say about Pt and Pd? Are those the methods you employ?

[@sreetips]

Yes

[@Jkauppa]

gold + koh = in ethanol/water solution (gold hydroxide, Au(OH)2), might be electro-refinable/boosted by voltage, ie gold is a battery electrode, also

[@Jkauppa]

even without other solutes, molten koh at 360C and gold, then h2so4, then electroplate out

[@Jkauppa]

possibly naoh does the same as koh to gold, even molten

[@Jkauppa]

as with other KOH etching, the reaction might be slow

[@Jkauppa]

I would try electrolysis of ethanol-koh solution with a gold electrode, to make gold dissolve as gold hydroxide, if gold does not dissolve fast into ethanol-koh by itself

[@Jkauppa]

seems like gold hydroxide can be heated to 140C->300C to decompose to gold oxide then to gold

[@infernalchaos1066]

I'm curious if you ever try to recover any of the precious metals that may have vaporized and been trapped in the fume hood filters. Or if that's even possible. A comment you made about trying to minimize loss in another video made me think of this. I know you're busy, I know you get a ton of comments, but you're the best chemistry teacher I've ever had. Who better to ask? And if you can't get around to it, no worries. A lot of your viewers will jump in and answer that as well. I love this channel lol.

[@sreetips]

There probably is metals in the exhaust, but I’ve never tried to recover them.

[@rolandslone361]

I use just aqua regia to dissolve my Karat gold and it works fine. acid test shows 22kt gold. I get confused on many ways you purify gold

[@sreetips]

Dissolving karat gold straight away with aqua regia can be done but it’s not recommended. Eventually you’ll encounter passivation with silver chloride, and a very dirty solution that make recovery more difficult. As long as you’re willing to put up with Those then no problem. But I’ve found that inquarting with silver, parting with nitric then refining with aqua regia produces excellent, repeatable results. It’s the easier softer way. Plus I refine silver, so it makes more sense to use silver to refine the gold.

[@rolandslone361]

How do you inquarting with silver @@sreetips

[@sreetips]

Alloy silver with the karat gold

[@bluegreen2360]

Just something that's been mulling over in my head. Could you use the same technique for a gold cell that you use on your silver cell, but with a gold electrolyte, and how would you make the gold electrolyte?

[@sreetips]

Yes, I have a video posted recently.

[@larrykester8593]

Kevin, the first silver cell in the 3 or 4 L beaker, with the graphite anode bar. How much silver did it produce? How often did you harvest the Silver?

[@sreetips]

It was a one liter beaker. I can’t remember what the output was on that.

[@larrykester8593]

@@sreetips it probably just appeared larger. My sight is not like it used to be. I’ve probably got have the stuff at home or on the way to the house for my silver cell build!

[@infernalchaos1066]

I just got my first beakers and flasks this week. They do appear larger in the videos, but that is just perspective. Now that I'm looking I see that they're the same size. Sreetips gives us his pov, instead of placing the cameras off to the side. Which would probably be easier for him, but it wouldn't be the same.

[@debcamp2359]

[@zubairhakda]

Which filter do you use? Which should be used to filter impurities from silver nitrate

[@sreetips]

I use lab grade filters to filter out solids from my silver nitrate solutions.

[@navrangstudio8273]

Sir how are you I have ground many stones and dissolved them in Aqua Regia (stones with stannous chlorid test show Platinum group metals) after urea adding SMB and some Iron sulphide ten grams dust was received around I once again made Aqua Regia to make pure gold, half of the dust did not dissolve, I do not understand what metal it could be.

[@sreetips]

I don’t have any experience with ground up stone.

[@christopherleubner6633]

Tellurium as Au2Te3 will do that. Best process for ore is to grind up than roast to get rid of the sulfur and volatile metals you likely won't want. Next treat with a mix of hydrochloric and dilute sulfuric. This will pull out the non PGMs using inexpensive acids. Next use nitric to pull the silver and palladium out if any. Then add HCl plus nitric to grab your gold and more noble pgms

[@noxitoutofthepark4027]

Will copper plate out onto a stainless Steel bowl like silver does?

[@sreetips]

If the voltage is kept at 3.5 VDC and the copper concentration is kept below 60g per liter then the copper shouldn’t plate out with the silver.

[@Camelguy069]

Let's do this!!

[@stormdrifter7904]

Nice

[@THR33STEP]

When you have silver in solution and only silver, what color would the filter paper turn if you hit it with Stanis chloride?

[@sreetips]

Stannous testing solution has HCl. So I’d expect it to form silver chloride on the test strip.

[@THR33STEP]

@@sreetips Ahh!! Thank you! Maybe you can try it out next time you whip up a batch of electrolyte. That would be cool to check out!

[@christopherleubner6633]

White that slowly turns dark. This is in contrast to pgms and gold that immediately have a dark reaction.

[@jimwednt1229]

What is that orange-brown vapor that develops in the beaker when you're doing nitric acid boils ? Edit : I've been seeing it in your refining for a few years and I finally thought to ask .😅

At the end of part 2, I was yelling at the screen. "Test the solutions!" You knew what to do. I know you are "making this up as you go", but you should really create a planned process. You seem to be going in circles here. Putting multiple metals into solution, then precipating them both out, then putting them both back into solution. You started with filters full of slimes, then in end you had filters full of precipitates.

[@sreetips]

These filters are very difficult. The yields will be low. I’m working around the camera. There’s very little interest from my viewers. I’ll probably never attempt to shoot another video of these ever again. Giant pain.
