Use electrowinning to remove the copper and save serious cash on nitric acid. I use this material all the time at work and have bought 10lbs for cheap awhile back to play with. For fun and in small quantities, sure nitric. 35lbs….I’d build an electrowinning set up. And the precipitate in the video could be phosphorus??? I know they use some of that in stay silv for a self flux as it goes molten it burns up creating a tiny atmosphere, but when dissolving it could turn into a powder. I have the msd sheets in my cupboard.

I have to suspect there were some other metals in those brazing rods. Maybe some silicon? On the packaging is the composition clearly stated as 15% Ag and 85% Cu and nothing else? There are many, many brazing alloys and I am not going to tell you I have used more than the most common ones but at minimum they have 5% phosphorus; others have highly variable mixtures of Zinc, or Tin www.harrisproductsgroup.com/en/Products/Alloys/Brazing/High-Silver/Safety-Silv-30.aspx all sorts of things that will interfere with your nitric Ag/Cu dissolve. And it acted that way.

According to the data sheet for Stay-Silv 15, it contains 15% silver, 5% phosphorous, and 80% copper. This is where all the nitric went. And it's the reason that very little silver chloride precipitated out in the first try. As the silver dissolved out, it came right back out of solution on to the copper, consuming the nitric acid as it went. The copper consumed the nitric, and the silver consumed the nitric, but the silver consumed the most. With the large amount (80%) of metallic copper present, the small amount (15%) of silver would dissolve, cement out, dissolve, cement out, dissolve, cement out, on to the copper, over and over, consuming nitric acid as it (the silver) cycled in the solution over and over.

With those rods containing 5% phosphorus I'm curious how that would have affected the nitric acid reaction with the copper and silver. Was the copper being pulled by the nitric while the phosphorus reacted to form phosphoric acid and NO2 and then react again with the phosphoric acid to form copper phosphate? Was that the precipitate that was first noticed?
@sreetips

I must confess that I don't know the answers. The precipitate would dissolve upon addition of fresh nitric acid. The copper went into solution, obviously, but I have no idea what happened to the phosphorus.

Getting the copper is easy, just add the copper solution to a container full of iron. The copper will precipitate on the iron as a fine copper powder and fall to the bottom of the container as nearly pure copper metal. The iron goes into solution as the copper comes out of solution. However, if other metals are present that are lower down the list in the reactivity series of metals, then they too will precipitate out with the copper. I'll do a video on the reactivity series of metals. It's so important to understand how it works and is applicable at every level of refining precious metals, as well as non-precious metals.

Brett Davies the words etymology started out from Latin as from the word “solidus” but then was transformed into old French as “souder” then “soudure” and then “solder” in Middle English. So, pronouncing without the L is the more modern and correct pronunciation and including the L would be a much more ancient and archaic pronunciation based off of the Latin.

Thanks for this video, I *think* that I can determine a way to apply this profitably: I work in HVAC and am also a beginner hobby refiner. I already seperate/cut my clean copper scrap from the soldered joints when cashing it in because of the superior payout on the clean versus soldered. If I use the silver soldered copper in order to precipitate silver out of nitric (if Im already doing that anyway) then I can seperate the silver from the copper *and* cement the silver out at the same time. Thanks again.

Good question; No great answer, other than it just is. It does not have a widespread "common" use. There is a lot more Federal scrutiny applicable to it and it isn't available just anywhere. If it gets shipped in a goofball container and leaks, virtually any metal it contacts will produce NO2 nitrogen dioxide the red fumes which is fiendishly toxic; Can kill you (by instantly destroying your lungs) if you get a good breath; over and above the typical burns any strong acid will produce. Hydrochloric, you can buy at pool supply stores, maybe even Home Depot. Sulfuric is battery acid. There's no "ho hum" use for nitric.

Just caught this video and you have probably already figured it out but... Those silver brazing rods are 5% phosphorus. With nitric acid, that will redox to phosphoric acid, which should not effect what you were doing, but that and some miscelaneous impruities and manufacturing slag, were most likely the "unknown precipitate". I'm a little fuzzy on the subject, but silver nitrate (I) with phosphoric acid, i think will create silver orthophosphate. I'm not exactly sure what that reaction would have had done in your mix, but possibly lowering the yield and leaving some yellowish sludge. In a perfect world (by equation) it takes 4.3ml of azeotropic nitric acid (68ish percent) to dissolve 1gram of copper. At 80% copper in the material, that would have required 1567ml of conc. nitric to get the job done (ouch!). Not to mention the H20 need for solubility. Add in the 82.96ml of nitric needed for dissolving the 15% silver (68.37g) at 1.22ml HNO3 per gram of Ag. The nitric need for copper is why whenever I need to inquart, I much prefer silver to keep the refining costs down (Ag is 28% of the cost of processing Cu). So... my opinion is... two things were battling you (1) a ton of nitric required and (2) possibly some interactions with phosphorus. Maybe a high power chemist could enlighten us further.

I'm going to suggest you convert the silver chloride to silver metal by drying it, add 1.5 x molar sodium carbonaste< and just melt in graphite crucible. The carbonate/chloride xixture melts at about 800°C and serves very weLL as a flux. No need to make things all sticky with borax. Just melt and pour beautiful metallic silver. Nickel does not interfere, nor does tin oxide. Easy peasy, no need to reduce before melting. Chemical reduction is not only unnecessary but vastly complicates the mechanics. My technique is dissolve, then prepip as chloride, add 1.5x molar amount of anhydrous sodium carbonate, dump in a crucible and melt. then pour off in graphite bar mold.
@sreetips
Жыл бұрын
Harold_V on the GRF said he tried this method with good results. He said that the crucible must not be over-filled with the chloride. I think he recommended no more than 1/4 full of the dried silver chloride. Because it will boil over with the carbonate and create a big mess in the furnace. I prefer the wet chemical process myself.

That would be an accurate conclusion Scott. There is just too much copper in that alloy to make it profitable.

Rather than using expensive nitric to try and extract the small amount of silver, why not try and use economical HCl and go after the base metals which is the majority of the makeup? Very little if any silver will go into solution as it would be precipitated out by the copper or not react with the acid as it would form a very thin layer of silver chloride.

_"According to the data sheet for Stay-Silv 15, it contains 15% silver, 5% phosphorous, and 80% copper"_ Sreetips stated in an earlier comment - so the only "base metal" here would be Cu, which cannot be dissolved in HCl. Any metal "above" hydrogen in galvanic series cannot be "just dissolved" by acids, as their electrochemical potentials are higher than those of H+ cation, so they can't just "replace" the hydrogen in acid like Fe or Zn. These are copper (Cu), mercury (Hg), tin (Sn), silver (Ag), platinum (Pt), gold (Au) - see tables on either pl.wikipedia.org/wiki/Szereg_napięciowy_metali or fi.wikipedia.org/wiki/Metallien_sähkökemiallinen_jännitesarja (those are the only ones showing it clearly, and elemental metals only). Those metals need to be oxidised first, hence nitric acid - a strong oxidiser - and that's why there are fumes of nitric (IV) oxide, NO2, which is a by-product of the first stage of dissolving (which is the oxidation). Probably highly concentrated sulphuric acid (98% H2SO4, which is several times cheaper) could be used as it has some oxidising property, AND Ag2SO4 is soluble in H2SO4 solutions, but it'll take a lot of time.

The nitric cost as much as any silver you recovered. How is that worth it, other than just making a video? The video will make more money than the silver.

For Copper in dilute nitric : 3Cu + 8 HNO3 _> 3Cu(HNO3)2 + 4H20 + 2NO = 3 (63,5) + 8(63) -> 3(188) + 4(18) + 2(30) so I need 1 liter = 8 mol nitric to dissolve 190 grams of Copper..with that reaktion also 72 grams of water is produced. But as we have seen in the Soluability tables Copper nitrate dissolves much less in aqueous solution than SilverNitrate....I put some effort in it Mr. Sreetips...I hope you can digest this.

Yes, you have a firm grasp on the chemistry. I know very little about the chemistry. I just go by the seat of my pants relying on my experience to pull me through. Thank you for that analysis.

So many of these experiments/recoveries is a net loss of money. Just on the melt value of the precious metals. Not including all the other supplies. Still, fun and interesting to watch. But definitely not a money maker. So, what makes the money?
