Silver Coated Copper Wire REDO With Nitric Pt2

Hello Senior, great vid. Could watch these all day. Keep them coming. Have yourself a great summer. Take yourself and Mrs Streetips on a nice vacation. Thanks.

[@robharp6973]

I have had this liquid form several times as I recover silver from dirtier sources. I use copper and chloride methods of recovery. I tested the liquid with a ph strip and found it to be neutral which would indicate a salt. My assumption is that it is Silver chloride and have been adding Sodium carbonate to my melts. Seems to help clean up things. And yes...I know about assumptions! : )

[@sreetips]

Sodium carbonate is what my mentor, Harold_V on the goldrefiningforum.com, used to get pure silver from silver chloride.

[@Alondro77]

Silver chloride would make sense. Very finely divided silver does seem to react slowly with concentrated hydrochloric acid. It's probably better to wash silver powder with no more than 1M HCl.

[@4DRC_]

I think it looks better like this than if it were a perfectly smooth puck. It gives it character, it looks just like the moon.

[@silverscorpions4102]

I had a batch of 450g of Sterling already in process when I saw this video. Today I went to rinse my cement silver and ended up with the same green mess you had. I'm relatively sure the source of mine was previously used copper in the process. when I pulled them out there was a reddish layer under the silver still on the copper which I rinsed off into the silver without thinking. I believe it was some form of copper oxide or chloride. Hence, MAJOR copper contamination in the silver. I didn't use your Hcl method, I just kept rinsing, and eventually got the green tint to go away. However, the silver had a bronze colored tint and flamed bright green when melted. I will only use fresh copper in the future and remove it right near the end of the reaction. The used copper will then go directly to the stock pot...not to be used for cementing a batch of silver again. Thanks for your videos! Your videos are what brought my attention to this hobby several years ago. Was not surprised when your hat showed you to be a fellow MM.

[@gsracer]

I have had the same issue as Sreetips and you, its some form of copper oxide, green tint in the cement, and a green mess. Eventually you can rinse it out. My experience is 3 causes of this. 1. Re-using the copper, from previous cementations. I pour my own copper ingots to use for cementation, i store them in the stock pot in between cementation. What i do is before i reuse them, i take a stainless steel brush and brush the copper oxide layer into the stock pot till i get shiny copper for using to cement. 2. To much free nitric which starts dissolving the copper and makes for really dirty cement silver. 3. Leaving copper exposed out of the solution while cementing. Seems like Sreetips had a similar issue, any way. Great video as usual, you where the one that got me into this hobby!

[@Lordtheobald]

I could be very wrong, but it seems like the liquid could have been a variation of copper salt. But that's a wild guess.

[@kieranodea771]

Yep, that's copper chloride

[@shywatcher1961]

that was very interesting the way all that liquid formed in the melt dish...

[@mikedickinson9730]

6:35 those are some beautiful colors in the beaker there.

[@Jrny32]

Heck yes, a bedtime treat

[@goranaxelsson1409]

My guess on that strange liquid forming in the melt dish would be silver chloride. Formed by rinsing the cemented silver in hydrochloric acid. With the right flux you could turn it back into metallic silver in the melt dish.

[@sreetips]

Harold used to use sodium carbonate to convert silver chloride into metallic silver.

[@Navschannel3908]

If we go backwards to the original product "Silver coated copper wire"... the "coating" material is usually a combination of lead and zinc with silver to create the "coating" such as it is. The only material that could have "melted" with the silver and have such a dramatic response to dropping into water, is lead. So my guess, is you found lead, and a bit of sulphuric acid would strip that out, and your filter would have caught it .

[@johnh8615]

You need to use your furnace like mount baker mining and metals .he uses a collector metal of lead to evaporate off waste contaminants into oxides and they move into the assay crucible and leaves only pure money metals. Must be done outside so that it won’t poison you with the gases.

[@Alondro77]

Once I start doing large batches of this, I'm going to catch the NO2 and pipe it through a bubbler into a tall column of water enriched with a little peroxide, to regenerate weak nitric acid. I can also boil the iron nitrate, which will decompose it into NO2 (again, bubbled back into water to recover nitric acid) and insoluble iron oxide! :]

[@chrismsmalley2626]

Question ? With that Silver Chloride , where do you buy Lion Sugar ? How many Lions does it take to make a pound of that sugar ? Is that why they are going extinct ?

[@sreetips]

Yes

[@Red9GearHeads]

Rhodium can present as red, as can palladium. It’s possible your wire was coated to prevent oxidation.

[@kieranodea771]

That green color is Copper nitrate turning into Copper chloride. Its normally not stable in solutions containing nitrate's and reverts back to copper nitrate but with an excess of hcl it will remain. You can observe this by adding Hcl to Copper nitrate solutions and you'll see a green color for a moment then it'll turn blue again.

[@sreetips]

I’ve got some copper salts sitting on top of the cement silver from the filter papers that I refined recently. Still trying to figure out how to separate the cement silver from those salts.

[@kieranodea771]

@@sreetips Perhaps rinsing with pretty dilute H2so4 ? The copper cation is even more strongly attracted to the sulfate anion then the nitrate one. So it will readily jump to being a sulfate salt which is a lot more soluble at low temps

[@Alondro77]

I have a weird wire that's copper coated, but some other metal underneath that is totally resistant to nitric acid! What could it be? I have a hard time believing it'd be platinum, though it was from an old pH broken meter... those were quite expensive, so mayyyybe.

Thank you for the video as always! What determines whether you do the copper plating method or go the precipitation of silver chloride and then treating the solids with causitc/sugar?

[@jaspcardoso8]

From what I've seen, he always do the copper plating method. He did some times with the sugar but although it's cheaper in term of materials, it takes longer, it's messier and produces a ton of waste water that needs further treatment to dump.

[@Hossak]

@@jaspcardoso8 Thanks for that. I have since gone through a few of his videos using the caustic/sugar method, yep it looks like a right mess of a thing and produces a good deal of solution that you have to treat. Chemically fascinating but a pain in the butt.

[@LilMilely]

Can you please do a experience on recovering the silver from Silver Contacts?

[@Gainn]

My first thought was that the liquid was oxidised dinitrogen pentoxide, but it's probably just boric acid.

[@peterdidonato1590]

How many pounds of silver plated copper wire did you use? I have 5 lb going to 6 lb. Were you able to separate the silver and the copper that way you have silver and copper in your hand?

[@sreetips]

Yes, but it’s not very efficient: it will cost more in time and effort than the metals separated are worth. Best to just leave it along and hang on to the silver/copper wire.

[@davidmccrary8136]

Hey buddy quick question man before I buy all these ladies watches the old ones just got to go field caps and the gold field bezel they're like road gold plated do you know how much one of those yields before I buy 60 of them we just want to know if I was making a good deal or not before I purchased this mini if you know would be greatly appreciated

[@sreetips]

Weight of the metal in grams times 0.025 equals what the expected yield in pure gold will be. The only way to tell is to remove the crystal and the movements and weigh the metal by itself.

[@nicolebacon3230]

yea so want to see you recover from the filter papers!!!

[@Alondro77]

Many of the electronics parts I test dissolve with nitric acid a whitish goop along with the typical very blue solution. I'm assuming it's a bismuth compound. Pre-treating all the components with hydrochloric first should remove it.

So what's the difference between using copper and using lye and sugar

[@sreetips]

Platinum group metals follow silver through the process. Cementing on copper will also bring down these metals. Silver chloride to metallic silver with lye and sugar will not get the PGMs. Plus silver chloride conversion creates a lot more waste that must be treated prior to disposal.
