Thank you!

I think you could have an hour long video of you pouring and weighing all types of precious metals and I would NOT get bored for a second!! I just love to watch that stuff!!

Cute lil button! You coulda made enough of those to button your whole shirt! :D Thanx buddy!

Great video and nice button. If I recall you were going to stop processing platinum group metals due to the health effects when in salt form, do you still plan to do so or is that only after your current wastes and stockpot are done? So you used the borax to limit the risks of the salts becoming airborne when melting?

They can't become airborne when melting:they immediately decompose below 500°C!

I truly enjoy watching and learning. I have a question for you would it be worth while to make a video of getting an old cpu and take all the complete boards and with the use of pyrolization and incineration and ball mill. Or the like break it all down then melt it all down to one one chunk of nonferous metal.than in turn separate and refine all the different metals to include the non precious metals and find the yields of what can be found? Sorry about the long question,comment. Thanks again for all your awesome videos.

That would make an interesting video. But it's probably not something that I would try to do.

I can't quite tell. Was the palladium still in the filter paper when you calcined it? I didn't know you could do that. I was once told that the palladium would absorb some carbon thereby contaminating it. If it's ok to do this that'll make things WAY easier for me later on. :)

I'll have to get back to you on that. I may send in a piece to the big refiner after calcining with the filter paper. They will assay with XRF. If carbon is present as a contaminant then it will report in their assay. I'm new to PGM refining. We can both learn something.

I always follow you. Palladium is good but waiting for your last converter's platinum video.

Hello, Sreetips! Really enjoy your videos! I was wondering... when separating palladium from PM refining solutions, instead of using DMG or NaClO4 to drop the palladium... can one just use pure silver metal to cement out Pd, as Ag is higher on the reactivity series for metals?

@sreetips

5 жыл бұрын

I don't think using silver is a good idea. Silver chloride would definitely be a problem. But I've never tried it so I don't have any experience. DMG will get the Pd (and Pt) to drop out of a silver nitrate solution. Then just filter the fluffy yellow precipitate that the DMG makes and dissolve it in aqua regia.

More specifically... do you think it might work for the nitrate solution from the inquartation process? Last two batches of inquarted karat gold i processed turned up green nitrate solution. This solution turns stannous test brown. Assuming Pd is present. As DMG is expensive and NaClO4 is dangerous, I was hoping that I could drop Pd with Ag, before dropping Ag with Cu.

I see where you're going. I don't know. Silver and palladium are both soluble in nitric. But then so are silver and copper. Give it a try and see what happens. I buy DMG from GFS chemical. Last time it was about $100 for 500 grams and it will last me a long time. It's $50 for 100 grams on eBay. Please remember that DMG also drops platinum. I find DMG to be very effective in separating the PGMs from silver nitrate solutions.

Sreetips, need to bother you with a question, or anyone else that's wanting to chime in: been following a lot of your videos, recovering and refining. I've got a bit of powder, dust saved up now and ready to start experimenting with melting. Just reaching out for some advice as I have no torch experience...what is your recommendations/advice on using an electric kiln?

@sreetips

6 жыл бұрын

I've used a Kerr Electromelt to melt some silver a few times. And I calcined some Pt with it once. That's the only experience that I have with electric melting. I had some silver powder that was cemented with copper. Trying to get it to melt in an open face crucible was difficult because it was contaminated with copper and some PGMs. But in the Electromelt the temp inside the graphite crucible seemed to get much hotter (2000 F max) because it was down in the electric furnace and well insulated. I'll probably use it again for melting some silver powder for my silver cell or if I want to melt a large quantity of pure silver crystal for a 50 troy ounce bar of pure silver. I rarely use it, and the folks on GRF like to bash them, but it's nice to have it available. I do most of my melting with my torch because it's easier to set up and use.

Yeah, I check out your torch work, and I haven't the slightest clue on that note. So I'm thinking it would be best to start with the kiln to melt my gold powder. Thanks for reaching back out man!

If you have platinum or palladium to melt then forget the electric furnace. It only gets up to 2000 degrees F, well below the melt temp of Pt or Pd.

Palladium is actually a nightmare to melt sometimes!Even iridium is much easier regardless of vastly higher melting point!And this is because there is a crazy effect that occur when you melt it down which is spitting itself all over the place when it absorbs either carbon when you have a reducing flame and oxygen when oxidizing:upon solidifying it will release them and therefore spits itself everywhere!

For some strange reason I'm starting to see metal spitting out of the dish during my gold melts. It just started happening about this past year, never had it happen until now.

@johnsheppard1476

@@sreetipsif it's palladium than there can be 2 reasons why it usually behaves like that!So the first it's spitting like crazy if any carbon is introduced while it's molten:the reducing flame immediately does contaminate it with enough carbon(as when molten it will absorb all the carbon that will hit it's surface)-so when it solidifies it just starts spitting like crazy when expelling all that carbon!And another reason is that it can behave in the same way if any oxygen is forced into it's surface in case of oxidizing flame because it won't react with oxygen at those temperatures but will absorb it like carbon and spit afterwards! So maintaining the neutral flame all over the melting process is mandatory!

I use cyanide to leach, then zinc precip, then hot HCl soak 24 hours, then filter. I tried to melt with propane and borax, nope. Have to go oxi/acet. Ok I have hot nitric soak stuff that I copper piped over night with a off white grey precip. I was told its my silver, but I think palladium is also in it. Will it melt with propane and also grab melt the palladium if there is any? I think its called inquart.

Migel nitric will dissolve silver and palladium. Adding any kind of chloride such as sodium chloride or hydrochloric acid will instantly precipitate silver chloride. But the palladium won't form a chloride.

@@sreetips ok thanks. Now your saying dissolve in hot Nitric/water, then drop the silver by adding HCl to it. Now can that silver chloride be melted as it is? I was told I can drop the palladium with sodium cyanide, since I have it? So I can add salt to the Nitric/water and that will also drop the silver? Can that precip be melted as is? Could I denox the nitric/water then add water and HCl,then zinc to drop the palladium?
