I have a suggestion for consolidating your high melting metal powders into a chunk of metal. You could take the mud from electrowinning the Pt and Pd out of Cu and dry it out to get metal powder. When we work with precious metal powders in the lab, we press them into pellets in a pellet die then melt them in an arc melter. You will not need an inert atmosphere to melt Pt or Pd so you could use a TIG torch to melt them. Use a large, clean block of copper as a hearth plate and the metal should not stick (unless you get the copper too hot).

I think your Idea of adding silver to reduce the melting point of the lead alloy was a good idea.

Industrial separation of cats is usually done with very high heat and using iron as the collection metal though some use copper. I also know that the honeycomb is burnt off before being milled into a fine powder in a ball mill. Also of note is that newer iron sulfide methods of extraction are being used as they can operate at a temp of only 950 deg C.

Just FYI, the tantalum peaks and platinum peaks for some types of xrf guns can overlap to the point where even 100% pure platinum will be read as tantalum. Codyslab has the same problem with gold and tungsten, the reason is because the gold and tungsten X-ray detection peaks are so close together the machine can’t decide which element signal it is. The same problem occurs with tantalum and platinum. Contact the customer support for your particular brand of xrf gun to determine if this is a known problem. Also try maybe shooting a sample of known platinum concentration, something where it’s impossible to have tantalum contamination and see what reading you get.

Jason keep up the great work — in the name of Science !!

Thanks for your videos!!

[shaneyork]

Looking forward to see the beads getting smelted!!
Have a GREAT Day!!!

[emandejnozka]

Thanks, Jason. Raising your algorithm. Lotsa work for small recovery, so far - keep up the good work; I’m looking forward to your next video.

In addition to tantalum, I also noticed some vanadium. Both metals can be used in NOX converters. The converter you used had two distinct sections. Perhaps the upstream section was for NOX and the downstream a typical converter.

[oscaranderson]

I do believe you're the first person to smelt down a converter. And show us how much is actually in it. Very good content..👍

They used ion-exchange resins to separate the Pt and Rh. The RhCl3 is what came out of the ion-exchange resin column.

I could watch this for days . Great stuff I'm fascinated with this . Great job

[chibigon]

The platinum in the ceramic beads can be recovered directly from the beads with a complex reaction. I think you will have higher Pt recovery from the complex reaction process than from the smelting process.

Cupellation
a refining process in metallurgy where ores or alloyed metals are treated under very high temperatures &
non oxidizing precious metals remain apart, and the others react, forming slags or other compounds

I like the idea of silver as a collector, the button could then be dissolved in nitric, putting the silver and palladium into solution and leaving only the platinum at the bottom of a beaker. Then the silver and palladium could each be brought out of solution, one at a time, thus separating those two from each other.

hey Jason cool video man :) great to see all the skills used in smelting : I won't pretend i know much about this :) but I will say I love watching these type of videos :)

[RalphReagan]

This is what I found:

One of the main uses of tantalum is in the production of electronic components. An oxide layer which forms on the surface of tantalum can act as an insulating (dielectric) layer. Because tantalum can be used to coat other metals with a very thin layer, a high capacitance can be achieved in a small volume.

[teodoroanguay]

I always watching you're smelting... For I have some platinum for smelting...tnx for learning jason

[ShadwBoxxer]

use catalytic converters you pulled off yourself, if you buy them from ebay they are usually chemically treated to get all the precious metals out

[drevil]

I'm binge watching this dude. I have no f-ing idea what he is doing but i dig it it a lot.

[macclark]

I worked at both the Stillwater Smelter & Base Metals Refinery in Columbus Montana. We’d actually smelt down Bulk Bags of Catalyst. The end result was a black powder we sent to Engelhard Refinery for end process. They’d keep the Gold / Silver and we’d get the Platinum/Palladium. I will say we had all the mined metal from the Nye Montana and East Boulder.

💯 to the channel and your recovery efforts.
Thx. For the knowledge.
