Very clever and wonderful process to watch from start to finish. I have learnt so much from your videos. Thank you sir.

[@Alsacien]

14 grams of gold is insane. Congrats! When I replied to the guy who wrote that it was foolish to go after what was left in the filters a few weeks ago, my prediction was that you'd end up with a bead of gold, a bead of platinum group metals, a few ounces of silver and satisfied viewers who learned something, but by "bead" I meant maybe 3 grams! It would be amazing to know how many kilograms of silver crystals came out of the silver cell to obtain 14 grams of gold from the impurities, but I suppose that this might be proprietary information. ;-) Looking at the mess you had to deal with in the first third of the video, I didn't expect it to end on such a high note! Thanks for yet another fascinating series!

[@sreetips]

Boiling nitric puts traces of gold in solution. Then it follows the silver into the anode basket.

[@Alsacien]

@@sreetips That was my theory too. That those traces would accumulate into a total of 14g of gold is a testament to how much impure silver shot went through the silver cell! I hope that you kept enough information to be able to calculate a yield (how many grams of gold per kilogram of pure silver crystals), even if you choose to keep it private.

[@jamescball55]

I have done chemistry research my whole career (retired now). Your video is an outstanding example of research when the unexpected happens - which, ironically, happens all the time. You show a very methodical and reasoned approach to problem solving. I love it. Wish I was back in the lab. Keep it up!! On another note I am going to make a silver cell with glass instead of a SS bowl. I love watching crystals grow. I have watched all your silver cell videos with facination.

[@RyanEglitis]

Don't you need a metal bowl to run a current through to grow the crystals?

[@jamescball55]

My plan is to use a SS strip about 4 in wide the length of the glass vase as the other electrode.

[@sreetips]

Yes

[@RyanEglitis]

@@dunravin But then all the growth is from that cathode instead of the entire bowl surface.

[@RyanEglitis]

@@dunravin A glass cover would give similar visibility, without the warping effect of a bowl bottom.

[@rogerclaiborne6815]

He's not kidding about the dangers of those fumes. Doesn't take much. Wish I would have stayed away from messing with this stuff years ago. Outside where the wind constantly changes directions doesn't cut it, got to have a good fume hood set up like he does.

[@rom65536]

They don't call it "Brown Death" for nothing. I hope you didn't get too much of it.

[@Alsacien]

Excellent advice. Nitrogen dioxide is heavier than air, so it has a tendency to stick around if it isn't aspirated away by a good fume hood. Were you able to smell it sometimes? Could you expand a bit on your current symptoms, please?

[@sreetips]

Outside is just too dangerous. Even if approached upwind of the reaction, the wind forms eddy currents that pull the fumes right into your face. Even if you hold your breath, turn and walk ten paces, the fumes are still in your hair, clothes, eyes and skin. When you do breath you can still smell them. And if you can smell them then that means you’ve exposed your lungs. Doing these reactions without a fume hood is too dangerous.

[@sreetips]

When I first started, I didn’t have a fume hood. I did it in my back yard. I immediately noticed muscle cramps in my legs out of nowhere. My lungs do produce mucus at an abnormal rate. I’m sure that in the end, my exposure during my time with no fume hood, has caused irreversible damage.

[@rogerclaiborne6815]

I got COPD and it may have contributed to some of that. I'm a construction worker and was exposed to a lot of dust as well. May be partially why I have some chronic sinus issues. I stay away from doctors as much as I can so don't know it for a fact. Just a suspicion. @@Alsacien

On another note i refer everyone interested in refining to your KZbin. Not that you need the added support but you're still the goto for knowledge and never giving up. A youtuber named bigstacked melts down non ferrous metals mostly but he has a pile of silver contacts and sounds like he was ready to try something with them. So naturally ive been teying to get him to watxh you. Keep up the great work. I hope you love what you do because your viewers sure do.

Well come back Mr. Sreetips!!! Welcome back, looking forward to the full length videos. ❤

[@Joe.Rogan.]

It's so interesting to see how metals follow each other. That gold came from silver shot that was basically almost pure silver to begin with. By using a silver cell to extract only the silver from the silver shot and capture a the miniscule amounts of other metals in a vacuum filter bag then refine that down into its individual elements is amazing. This would be considered magic in the olden days.

[@sreetips]

I think the gold came from the nitric boils I do on inquarted gold. Hot nitric will put traces of gold in solution. Then it follows the silver into the anode basket of the silver cell.

[@Joe.Rogan.]

@@sreetips Yeah that makes sense. 14g of gold just seems nuts to me.

[@jeepin4on4]

Thanks for this lesson. Silver cell anode filters and you recovered Gold. Question is, where did the gold come from? Most of your silver is from sterling silver ware that I see or watch. Should I buy every sterling set I find and go through the process of refining gold silver and trace amount of palladium? I never get platinum or rhodium ( too impatient i guess).

[@Alsacien]

It must be coming from two sources. 1) Impurities in the silver objects he dissolves directly into hot nitric acid. 2) Minuscule amounts of gold that go into solution with the hot nitric acid baths when Sreetips works on refining gold. Then the gold from these two sources cements out of the solution onto pieces of copper along with the silver and ends up as impurities in the silver shot that is used to feed the silver cell.

[@jeepin4on4]

I did not know that gold will cement out on copper, thanks.

[@apveening]

@@jeepin4on4 Check the reactivity tables, everything above (or below, depending on direction) copper will cement out on copper. That includes, but is not limited to silver, gold and all PGMs. Copper in its turn (together with the aforementioned group) will cement out on iron, which again will cement out on zinc (if you wish to recover iron).

[@sreetips]

Silver is a carrier of gold and platinum group metals. Hot nitric boils will put traces of gold in solution. Then, it follows the silver.

[@BrokenTWelder]

Another awesome to watch refining. Great job Senior Chief

[@Rob337_aka_CancelProof]

3:06 Thank you for doing that in time-lapse but I'm curious why you chose to pipette instead of decanting? I obviously missed something but I'm unsure as to win and with multiple videos preceding this one I was hoping you could just help me out with that

[@newtronix]

Excellent! Well worth the processes!

[@rogerclaiborne6815]

Who knew silver scraps had so much palladium, platinum, and gold impurities in it.

[@apveening]

The answer very clearly is sreetips ;)

[@sreetips]

I believe that the gold came from nitric boils of inquarted gold. Boiling nitric puts traces of gold in solution. Then it follows the silver.

[@bigdaddympd]

Have you looked into refining PGM into pure constituents? How do they do it in industrial refining?

[@sreetips]

If I get enough PGMs then I’ll try a refining.

[@erikferland6602]

I love the color of the gold in solution. It’s close to my favorite color.

[@sreetips]

Notice that it’s darker orange when hot. As it cools it turns more toward yellow.

[@ChrisCVW]

Really speaks to how important reprocessing all your “waste” is. How many attempts to capture that gold had it evaded before you finally got it in that ingot?

The gold probably came from nitric boils of inquarted gold.

Just goes to show how much gold is carried across with the silver from the nitic washes, totally surprised me.

[@nikolajwinther5955]

That's a surprisingly good explanation. I would say sreetips would be hard pressed to get that much gold, even if he processed gold plated silver only. And he never does. So where did it come from? The nicteic washes! Great that the gold is recovered.

[@sreetips]

The gold probably came from nitric boils of the inquarted gold.

[@nikolajwinther5955]

@@sreetips yes, you have sometimes confirmed gold in solution from nitric boils only. How much gold did you come across last time you did a anode-filter series?

[@sreetips]

Can’t remember, I’d have to look. But this one seems the highest amount recovered from these filters.

[@Rob337_aka_CancelProof]

4:30 I recently saw a buchner filter funnel (I think that's what it's called) that was easily the size of a dinner plate and likely had at least ten times the surface area you are working with currently that might be worth investing in if you're going to do this more in the future

[@kimberlynolz5725]

Oh he has one I believe it's a 10 or 12 in Buckner funnel

[@seymourpro6097]

Have you seen the price of big labware?

[@davidestabrook5367]

Instead of using big filters, the best technique is to learn how to make diatomaceous earth (D.E.) filtercakes. You add 1 teaspoon D.E. to a 60 mL plastic pot, then add 25 mL water (or solvent your filtering, like ethanol). Then swirl it around to make a slurry. You pour this onto a filter paper, and shake the Buchner to help it settle, then let it gravity filter until the water runs through. You then slowly add vacuum to pack it hard. Then refilter what runs through, until the water runs clear. D.E. filtercakes filter to submicron efficiency, at a reasonably fast drip rate. They can filter stuff that blocks paper filters instantly. You'll need to experiment to find out how much to use for your filter size, but a 2-5 mm D.E. filtercake layer is adequate. And you can scratch the D.E. with a glass rod, to expose fresh surface, when the filtration rate drops too low.

[@sreetips]

I’ll check it out. Thank you.

[@BigWeenieC]

I’m sure you’ve answered this in the past, but where do you source your chemicals for refining gold? I.e. Hydrochloric, Nitric and sulfuric acid… I’m sure it gets expensive!!

[@sreetips]

Mostly from the hardware store. Nitric from dudadiesel.com

[@TroubledOnePaydirt]

That color change around 18:25ish when he drops those ice cubes in, was wild! 🤯

[@kwinterburn]

Thinking about the difficulty separating the solids, I used to use pressure not a vacuum , started with a big syringe and a weight , it developed into a stainless funnel made from a piece of pipe with a threaded pipe fitting either end , the top had a airline connector , the bottom had a stainless mesh filter and a reducer stuck the vacuum on one end an 180 psi on the other and left it to it , bit of welding needed to get the filter supported properly , but it lasted for years , was used for extracting solids from transformer oil but the same process works for any material , there was a Russian idea years ago of using a open cell foam as the filter but you compressed the foam to get the filter size you wanted , then released the compression the foam sprang out and you could wash out the solid from the now very open filter ,

[@seymourpro6097]

Some mixtures will filter through a thick bed of filter pulp. Get some filter paper or kitchen paper and add a lot of water then blend it with a blender or similar (buy your own!) then, on top of a filter circle fill the buchner funnel and let it drip to near dryness. You should have a half inch thick disc of filter paper which will retain much more in it's thickness than a single filter circle can. (My last lab of work bought the bits of filter paper that the circle had been cut from, for just this purpose -we used a lot of it.)

[@sreetips]

This was like trying to filter Elmers Glue.

[@whatthefunction9140]

I lost track of where the gold came from. How did that much gold get in the silver shot?

[@ctvxl]

Most of the silver was used for gold refining. He in-quarts the gold with silver, then extracts the silver with nitric acid. While gold is not very reactive with hot nitric acid, some very small trace amounts do get dissolved in it.

[@apveening]

@@ctvxl And that ends up with the silver in the cement, which ends up as silver shot in the silver cells. And so the gold (and PGMs) end up in the silver cell slime.

[@sreetips]

Hot nitric boils put traces of gold in solution.

There's nothing else like it. I had one problem where no matter how much sodium carbonate I added, the pH didn't rise. And that's what started my learning about buffers, and so I started making buffer solutions, to get the pH where I wanted it.

[@sreetips]

My profit is not in paper dollars. It’s in pure gold. I’d have to sell the gold to realize a profit in dollars. And I ain’t selling any of my gold. My goal is to convert as much paper into gold as fast as I can. While it’s still dirt cheap.

[@ericmcc75]

@sreetips wise move. I appreciate your videos. So essentially, you are converting paper credits to metal ounces. With this conversion, are you seeing profit at the current exchange (again, considering input costs)?

[@prestontucker6171]

So is this amount of gold typical as "contamination" in your cement silver? I've got to think that it's coming from waste that ends up in your stock pot from other gold refining processes, right? Or is there really this much gold to be found in the sterling silver you process with your silver cells?

[@sreetips]

When I boil inquarted gold in nitric, the boiling nitric does put traces of gold in solution. These traces get poured off into my silver jar. Then they follow the silver into my silver cell anode filter. Gold is insoluble in the anode filter. It gets trapped in the filter. And that, I believe, is where all that gold comes from.

[@buggsy5]

I am surprised that so much gold followed the silver from your nitric acid digestions. In the inquartations, there are bound to be near molecular gold particles completely surrounded by your silver/copper used for inquartation and is too fine to be caught by your relatively coarse filters. As you stated, those minute particles would follow the silver.

[@sreetips]

Some of the gold dissolves in the hot nitric boils. It get poured off into the silver jar. Then cemented on copper along with the silver. The cement silver (with traces of gold in it) gets melted into shot and run through the silver cell. The gold is insoluble do it stays in the anode filter with the slimes.

huh? how was that much gold in your silver shot to be left behind in the silver cell anode filters? so basically the silver that cements out of the silver nitrate (that comes from the gold refining where you nitric boil out the silver in the enquarted gold) isn't entirely silver and somehow gold is coming out in the silver nitrate solution and cementing out onto the copper with the silver as well as the other less reactive metals aka PGMs?

[@sreetips]

That’s correct. Boiling nitric will put gold in solution during the nitric boils of the inquarted gold. The gold then follows the silver into the silver cell and gets trapped in the silver cell anode filter.

[@garymyers6638]

Do you have a person you can ask when things go wrong?

Not really. Most refiners are reluctant to give up their refining secrets. Especially to someone who they know will share it with the masses on KZbin.
