Pure Gold From My Filter Papers

[@davereeves1967]

Bro, I gotta give you props. You just spent a ton of time recovering less than a third of an ounce of gold because it would have been a waste of money to let it go, but you didn't break the 40 minute video down into parts to capitalize on the KZbin revenue. Because you know we would have all watched 2-4 videos of this as a series. Good man.

These videos where you recover metals from dirty sources a careless refiner might throw away are some of my favorites. I love the more basic ones too of course, like the last one with the catches, they refresh the memory and it's always a treat to watch gold solutions get clearer and clearer and then watch that high purity gold powder coalesce. I don't thank you nearly often enough for all this cool work you're sharing with us. You should be commanded for carrying that heavy looking microphone contraption on your head for hours on end alone. I've been thinking that a Zoom F2 recorder (no clipping ever thanks to 32-bit float recording magic) with a proximity omnidirectional lavalier microphone like the AT803 could be the perfect audio set up for you. It's not exactly cheap, but it's amazing hardware. I believe that you like to sync up the audio and video in real time directly in your phone as you film in order to save time in the editing room though and that isn't possible (as far as I know) with the Zoom F2 unfortunately.

[@kalicom2937]

@@sreetips I suggest that when you are filtering the results of your aqua region boil it would be better to avoid adding the solids in to the filter - repeatedly rinse the residues in the beaker until the solution runs clear. This is easier than rinsing and stirring the solids once they have been added to the filter funnel and you avoid the risk of ripping the paper.

[@sreetips]

Excellent suggestion. If I had thought it through then I probably would have done that. Inexperience due to infrequent type of scrap. Thank you.

[@fredrichardson9761]

Really nice recovery! I was wondering if it makes sense to save a bunch of these smaller recovery buttons after a single refining and then refine them all together to make a "three nines" gold bar. I can definitely see how a single refining of these buttons makes a lot of sense (from a time and materials perspective). Really nice video!

[@sreetips]

Yes, I’ve saved them up and refined them together myself.

[@AndyGraceMedia]

That's quite a collection of particles that didn't go through the screening process! Might be worth getting a coffee grinder to chop it up into little bits. They're super cheap. The coarse material will probably blunt the blades fairly quickly but they'd chop it all up into a finely divided state and any iron filings from the blades would be easily removable with a neodymium magnet.

The rainbow colors of the flames from the papers burning the different metals is so cool

[@Enjoymentboy]

Some people may look at these yields and be disappointed but I see it as the filtering process you use works very well. Ideally there shouldn't be anything there to recover so the less there is the better you've done the earlier stuff. But it reminds of the last few batches I've done over the last 3 weeks. I did some filters and I did another stockpot cleaning. The filters had almost no gold and only a few grams of silver, and I was good with that. After I siphoned off the copper rich liquor from the stockpot and into one with an old brake rotor in it I let it sit until no more copper came out of solution (at least 3 months). I've been recovering the copper mostly out of personal interest and curiosity and I've made a small copper electro cell. With this last stockpot I melted all the slimes and copper together and poured it as an anode bar. When I ran that through the cell there was a surprising amount of black dust building up on the bottoms of the cell. It was super rich in gold and PGMs which told me that there could be a lot left in that bucket after the copper appears to stop working. Testing the first stage in the stockpot showed no precious metals in solution but they sure came out on the iron. The copper from the cell is just going to go back to cementing silver. When I incinerated the filters I was shocked with a very sudden flare up and flash. I'm guessing that there were some filters in there that I had used when I recovered the KNO3 from my nitrate solutions. They provided a nice hit of O2 at the wrong moment. Whole yard smelled like fireworks for an hour. :)

[@busbey61]

What you do is fascinating! I remember watching cartoons with a chemist of some sort and beakers filled with colorful liquids that were green, blue, yellow, etc.... always thought that was unrealistic until YT recommended one of your videos! If I saw these videos in high school or college, I may have changed my focus, program or major. (Probably went the route of SOF in the military, but this is a close second for sure!)

[@neiljervis1]

Asked a question about centrifugal filters and some one mentioned a centrifuge . What I was trying on get to was repurposing a truck centrifuge oil filter or some of the old metal working machines used centrifugal filters. These would remove almost all of the particles as long as not in an acidic solution.

[@buckhood6425]

I truly love watching your stuff and how you have name on everything lol

[@FractalMachine]

i think you could have simplified the step in which you rinse the solids to get the dissolved gold out, which you stated gives diminishing returns, and also get much more out of those solids. rather than washing the solids while still in the filter paper, you could just dump the solids into a beaker with distilled water, stirred a bunch, let the solids settle, and then decant the beaker into the one containing your gold solution, and THEN filter the solids 1 more time, and you wont need to struggle with washing under vacuum and diminishing returns at all.

[@r0cketplumber]

I think the third step after charring and grinding should have been to burn it again with the electric furnace to get rid of all the carbon. That would reduce the amount of solids a lot and make the gold extraction and filtration much easier.

[@axminsterz4151]

[@christophersherman5587]

It's always a pleasure to watch you in action, once again turning trash into treasure. Out of curiosity, how much silver do you end up recovering from a filter run like this? I'm presuming that more of the value from this process is in that gold button, but I still end up wondering at the whole picture of what all you managed to extract.

[@sreetips]

There was probably 2 or 3 ounces of silver

There was probably a couple ounces in there. But I didn’t recover it completely. I added some more silver nitrate from my gold extraction to keep my stream of silver recovery flowing. It’s a never ending battle to keep up with the silver.

[@emrebingol527]

Great video! If I may have 2 recommendations to make your filtering much faster. You can use a plastic door mash cut out exactly to fit in between your filter paper and your funnel that will create More air flow. You can also use diatomite filtering media On top of your filtering paper so it does not clog up fast. You can also use fiberglass filtering paper to filter your gold at the end of your process so you end up with very dry Material with fiberglass filter paper that you can melt together. I enjoy your videos very much keep up the good work!

[@Ziegen-Sauger]

Good evening Mr Sreetips, a little south from our friend David below 😊 QQ if you don't mind. Just as disclaimer, the volumes you process are exponentially higher than mine. I am pouring my recovered Silver to 300g and 700g bars for optimization reasons, in my case filter papers and detricts (ruble from placer gold or gold filled scrap) really make a difference for me. I always process Silver apart from anything else, even as stock pot I have one for Silver waste only. The thing is, the material I process for gold always carry Silver that ends up in the form of Silver Cloride mixed up with detricts, droppings and rejects. At the end of the day, burn after burn, filtration after filtrstion, filtering after filtering all is left is carbonized plastic and organic material, several forms of dirt, and sundry trash detricts. The issue I learned is, if I accumulate this dirt black goo, it will contain reasonable amount of Silver Cloride. I once ran lye and sugar on the goo with acceptable but unjustifiable results because of the further rework of.the recovered cement Siver. From the metalurgic books from college that have been useful for me when messaging different alloys for my metal bars collection, there is a whole annex dedicated to "the solubility of Silver Cloride". Have you ever even have a slight thought about the Silver Cloride that likely just go to trash or for you it is unworthy to waste time since you already process ~60Kg of the purest Silver crystals in the world. Today while refining Silver filter papers, spilled Silver blobs from poring or smelting, e waste Silber, etc (I needed slightly over 100g of Silver of pour my last 700g bar). At the end I recovered ~20g of Silver from the goo, slag, and droos. It is relevant for me (the chemicals needed to separate Silver from the contaminated Silver Cloride is cheap. Wonder if you ever care for those. Cheers mate!!!!! Filter paper and stock pot defining are my faces by far.

[@hpdepasse5997]

Welcome. I refine gold and silver. After dissolving in acid, I filter the solutions to remove solids. The filter papers trap undissolved solids that may contain traces of precious metals. So I save all my filters. When I get a bucket full, then burn them and process them to recover any precious metals that they contain.

[@williamfoote2888]

Only the clueless would throw away those materials. I worked in the check lab for a world scale gold company doing fire assay analysis for 8 hours a day, day in, day out on 30 g ground rock samples. We’d inquart whatever gold was in the rock with 10ml of 0.1M AgNO3. After cupellation, we’d hit the dire bead with HNO3. We’d get several mg of gold, that we’d weigh record and then dump into a receiving vial. We had to run the samples anyway, so why not keep the gold. It’d take years to gather an ounce. No rush. And we’d recover the inquarted Ag as the chloride. No valuable metals went to the drain.
