Silver Cell Anode Filters Part 2 

Gooood evening from central Florida! Hope everyone has a great night! Excited for this video!

Man.. that Palladium/Silver solution gave me second hand anxiety.. but now I'm excited more than ever for the next episode. Seeing you problem solve on the fly is great content. The "main prize" is probably going to take a week to filter.. 10 hours in and you're not even at the bottom where all the material has settled. See you next week I guess haha...

You are spoiling us with so many videos, thank you! Learning so much

Good evening Sreetips, Oh the calamity in refining precious metals. That's what makes this hobby fun and challenging at times. Great content. Fun to follow along. Stay safe bud.

I really like how you keep your cool and think about how to correct the problem as opposed to just stopping.

Sure will be interesting to see your next step. The cementing out of silver with copper always looks so neat. 👍

Hello, Sreetips!! I totally enjoy your videos. Been watching for awhile. So educational. Keep them coming!!

God bless your heart on all that filtering!!!! The struggle is real!!!

Looks like it’s time to invest in a centrifuge! Spin down those hard to filter solutions before you filter them and you’ll save so much painful waiting

Amazing content as always. Thanks, Sreetips for the videos and inviting us into your lab.

Bean shaped pool gold !! If I could afford it I'd make a necklace outta that overflo bit!! So very beautiful

I’ll say it again, I am always so grateful to see when things don’t go as planned and the methods you use to get back on track. That’s where real learning happens.

you could totally make some merch. I love your use of "nitric". Slap that on a t-shirt. You got yourself a stew goin!

Thank you for all of these videos

always a great video!

Yesssss part 2!!!

Long time big fan sir..... Always love ur these series of stockpot refining, silver cell slime refining n filter paper stock refining..... Although missing longer videos..... Keep up ur great work sir

Your videos are very consistent and detailed, thank you. How can I reach you personally to ask you a question?

Watching that vacuum filter working on those solids is like watching that famous experiment testing the viscosity of pitch

Cool Chemistry!! Your best bet to separate the elemental silver from Pd(DMG)2 is to dissolve the Pd complex in hot ethanol or acetone -- the Ag should stay behind and be filtered off, and the Pd complex will recrystallize from the ethanol or acetone when you add some water Good Luck!!

Keep up the hard work❤💪!

Edge of my seat, can't wait for part 3.

Thank you!

Shine a flashlight from the back & you should be able to see through the dark liquid

Would recommend to use silver foils to cement the PGM's out of the nitric solution. So you could at least concentrate them

They need to make a filter with vaccuum down bottom, and positive pressure up top to help push the fluid through

I've been wanting to see this phase of the process for some time---recovering the ugly silver from the anode baskets. It's clearly not easy. I don't recall your having covered this phase before. And it also should be said that it reduces your silver yield, or said differently, ties up silver from your gross yield. I wonder if there is a melting solution to this issue. I have not checked the melting point of Pd or Pt nitrates, but Pd and Pt metals melt much, much higher than silver. In my estimation, unless you see some big problem with it, it would be worth it to take two anode baskets full of that ugly stuff and cornflake it.

I would love to see you do something with Titanium. I know it's not you're thing, I love your content regardless. But it is possible to get titanium jewellery these days and I just think with your skill, it would be interesting content from a knowledge and understanding point of view even if it's not necessarily profitable for you. Thumbs up for this video though, I'm mesmerized when I watch you're stuff, maybe it's just me but I still struggle with the idea of 'metals as a liquid' and I find it fascinating that you could have pot of fluid and basically decide which metal you would like to produce today, select your chosen acid/chemical and just watch the gold, silver or whatever literally fall out of the liquid. I'm blown away! and I've been watching you for years! 🙂

Great channel 👏

I was also surprised you didn’t do a stannous test on the filtrate prior to throwing in the copper to cement? Obviously you’re going to be running the silver through the cell again, but would have been nice to check for other pms before the cementation :)

I wish your videos were longer

As usual another fantastic video, looking forward to the next one ty sreetips 👍🏻

Sreetips I don't want to ask but I'm going to. I want a quick list of the items list for the gold refining. I'm setting up expense forecast and don't know the name of these beakers. But I want your setup. I have the silver cell list already help me out if you could. I'm your biggest fan. Your my favorite RU-vid dude! You are so well spoken, and can tell your a good old boy. God bless. I'd literally do anything for you! Thank you for teaching me value. God Bless! If you don't you don't worry about it! I'll be 👍

Hey sreetips I left a comment on your previous video that I think you will find helpful and with this vid I think you should dissolve the DMG PD salt in nitric acid then filter and add HCL to precipitate the silver out as silver chloride which would be easier then bubble chlorine through the PD solution or add sodium formate and boil the solution and lower the PH

First 👍's up sreetips thank you for sharing 😊

Mr. Sreetips, i have what might seem to be an odd request for you. Is there anyway you could make a 20-30min video thats just the sound of your fume hood along with the vacuum pump cycling maybe? That sound knocks me right out to sleep, i'd love to loop that noise all night, i'd sleep like a baby. No worries if not, i'm not so entitled that i expect you to actually do it, but it would be really nice 😁

Excellent.

Hi Sreetips... Have you got a video on how you ditill water? .... I see you use a lot.... Love the videos. Keep up the good work... Hello to Mrs Sreetips.... Sydney Australia.

Great video, but I had a few questions. 1. Does water dissolve the yellow precipitate? I know you use hydrochloric acid to rinse when you work with PGMs salts. 2. Would converting the silver nitrate to silver chloride been a bit easier to separate from the PGMs? I do get that the method makes a lot more waste, but could allow you to isolate the other metals more efficiently.

Whew almost a disaster but in typical sreetips grace you pull it out excellent video six stars sir

I cant wait to see your video buddy

Just kinda curious will you ever collaborate with any other RU-vidrs? Thank you so much I’m a loyal watcher of your content.

Yup missed the first part, I think I have it now ty

Love your videos, especially when you get outside your comfort zone! Just curious, is smelting a viable first step in this filter refinement process?

Curious if your dmg didn't come out of solution and look like silver? Interesting ride in any case! Keep them coming!

NOT FAIR !!! we now have to wait for Pt 3 ????

Palladuim black is what is in the beaker you can precept with vitamin c and soduim bicarbonate and a lil heat it flake the palladuim black out the way you can tell by the ink black mirror look on the beaker buddy lol great video

⭐️⭐️⭐️⭐️⭐️! Nice pivot and progress capture. But please please please consider making a temp backsplash for your filter station area for the DMG precipitates 🙏🏼🙏🏼🙏🏼 that was the only anxiety inducing part of the video for me. Tutorials on how to clean up walls and windows from chemical splash damage are not fun to watch nor the type of content you probably want to have to make 😅😉

SCIENCE!!! This project looks like it's going to take forever!

You should be able to end up with a clean 99+% palladium salt cake with almost no silver. It's a fascinating problem. I can only say that the possibility of encapsulation of silver chloride is possible and there are many other optional possibilities. It is important to add the DMG slowly with plenty of sheer mixing but I'd not expect significant silver in the salt cake.

Have you ever tried your ultrasonic to settle things? Not in it, but run it with your beaker sitting on top of it? Micro vibrations. Just throwing ideas out.

As always, thanks for the great videos, however I’m really curious why you decided to use DMG prior to an hcl precipitation of the silver? You KNOW how sensitive the silver in solution is, and performing an hcl drop of the silver, rinse and filtering, and then a DMG drop would have been my personal recommended method due to the obvious potential issues of having silver drop out with the slightest contamination of solution. I would have sworn you’d know better, but maybe you were simply experimenting or being curious with the DMG prior to au drop?

Offer still stands. I would love a in person class.

I usually remove silver first, by chloride. Then reduce the palladium by dmg (yellow complex) or sodium formate (black powder).

Good save with the DMT solution.

The silvery and bright yellow beakers, now that's something you don't see every day!

A learning curve for all

Pretty wild hair silver came out it's almost like a silver mirror if you ever had that happen before with DMG

nice work

I’ve been wondering if you could store the gold sponge material instead of melting it and pouring it into gold shot, buttons or bars? I was just thinking if your house was broken into most people wouldn’t even know what it is. I watch your videos way too much, by the way. It’s so interesting especially when you are figuring out new issues.

Its going to be a battle buddy

Do you take notes on how each experiment goes and try to improve/streamline the process for stuff like the stockpot series or gold filled/gold filled inquartation experiments?

It looks like the majority of your anode slimes (the gray power after removing the silver shot) was cement silver. So I'm wondering where it all came from. Your silver starts as shot with no power. It dissolves in the electrolyte when oxidized by the current. Most of it travels to the cathode bowl, but why is so much precipitating out in the anode basket? What could be reducing it there at the same electrode where it oxidized? My guess is that it's the copper impurity in your silver shot. We might expect all the copper to be oxidized by the electric current along with the silver. but as each copper atom is exposed (as the around it dissolves) there is a chance it will be oxidized by Ag+ ions, creating cement silver. So it would be worthwhile to reduce the copper content of your silver shot. Obviously, the Cu comes from the CuNO3 solution that the silver cements out of. Now CuNO3 is super soluble in water, and you wash the cement silver with boiling water. But it still contains some copper because we see the electrolyte turn blue. The human eye is not very sensitive to blue. Maybe rinsing until you can't see the blue tint isn't good enough. In a research lab you would use optical spectroscopy to verify the last rinse is clear. You could do something like that in your home lab, with just a white light, a photocell, and a volt meter. By comparing clean water to your rinse water you should measure less voltage from the photocell when there's copper in solution. It might be even easier to detect the copper ions fro the conductivity of the water. Pure distilled water doesn't conduct at all well, and any ions in solution will increase the conductivity immensely. Second, I would suggest boiling your cement silver in distilled water after rinsing (just like you do with your gold precipitate). And third, I suggest your rinse the silver with ammonia. If some of the CuNO3 is stuck to the silver surface the ammonia should release it.

I'll be looking forward to the next , thank you Sreetips 👍👍

Question: With respect to silver cementation, does it matter if the copper tube is left to rest on the bottom of the beaker or should it be raised as to not be covered by the cemented silver. Or does it not matter at all. Just curious if its a surface area exposure thing or just as long as the solution is in contact with the copper. Thanks in advance!

Thx for the video! Have u considered processing hard rock miineral??

Why don't you first precipitate silver from precious metal solutions in the form of AgCl? AgCl can then be reduced with aluminium/zink in acid, or by cathodic reduction

Question: I've seen you use lots of copper over the years, usually copper pipe, but have you ever fully recovered the copper and smelted it down to used to cement out silver? or is it too expensive and time consuming?

To remove the silver coating on your beakers, do you just boil a little nitric acid in them?

I guess leaving an organic molecule like DMG in solution for too long will trigger some kind of redox reaction, which will reduce the Ag+. and God knows what Pt or Pd, which are often used as catalysts, will do to organic molecules over time.

I forgot to mention the other day there is a healthy collectors market for Electrum. You will have no problem selling small Electrum buttons for the same price as 9999 gold plus a premium. People like it because of its history in ancient coinage and jewelers love it as do mineral collectors. Its hard to find someone to make it from pure gold and pure silver. Being man made is no problem to collectors. Might be a market for you.

Hello Sir, so, plot twist on the way, I am sure, we will learn something new...

I want to see how much palladium and platinum he is able to melt love these vids

Can you take 60 mils of liquid silver nitrate add distilled water and copper and still get silver crystals to grow?

Could you use a stronger vacuum? Or can you tear filter papers or something equally undesirable?

Please make silver ingots at the end 🙏

ever try lighting those filters on fire? basically old fashioned gun cotton right?

I would have checked the ph levels to prevent the silver from coming out of solution and joining the palladium

wonder if the paladium can be enquarted with the silver similar to what you do with the gold and be purrified with other acids that disolve the silver but not the paladium...

Silver Nitrate is sensitive to light, and can easily decompose, even under fluorescent lamps, to metallic silver

When I make my first million from poker, I’m putting together a pro grade lab and hitting the yard sales

I wonder if that was actually silver, or if it was somehow metallic palladium? I mean, the two metals look very similar. I’m not sure HOW exactly anything got reduced to metal like that but just something I thought might explain this a bit better maybe.

Oooof. Good luck.... I wonder what is gumming up that filter so badly.

Would redissolving (the palladium/silver precipitate) with Nitric Acid, and re-precipitating the palladium with DMG work? Edit: Teach me to comment before I watch the whole video! *laughs*

You say you're "making it up as you go along". Isn't there a standard process that refiners use that you could emulate?

Will you extract gold from crushed ore?

My rabbit sat through the whole thing. Maybe i can get him to help me refine silver 🤔

Found a video that used a clip of a video of yours. Channel is “Factora”. Video is called “ How GOLD is made.” Shows your clip starting at the 4:34 mark in the video.

How/where are you getting your nitric acid?

هل اصتدام النحاس الأحمر المنصهر في الماء على لوح خشبي يزيد وزن النحاس ارجو الرد 😮😮😮😮

If you make siver chloride then filter you get the silver out

❤😂🎉

Is this your main source of income? If not what is you’re line of work.

I'm pretty sure there is Paladium in the solution you threw the Copper pipe in. It will plate out now. You had to test it for Paladium.

Part 2 Cliffhanger.

Hello sir @sreetips I watch and followed you for awhile now and one time I decided to recover gold from computer ram as gold fingers but when i finished my first recovery and tried to sell the gold recover they say that the gold recovered from aqua regia is not pure, can you give me any advice why is it not pure as yours?

Already??

You might want to precipitate the silver before the palladium

That tortuous filtration is hard to watch, but I assume putting highly acidic liquids in a centrifuge is probably not the best idea.

Not exactly the best situation with the silver palladium, but I would imagine if you were to melt it up into shot and run it thru the silver cell it would probably remove the silver and leave behind the PMGs.
