A outlet for Iridium?

[lowgrade01]

I am looking for someone to purchase Iridium. Been calling around for days trying to find an outlet. The bars have been assayed and will have 1100ozt. They show up as 27% Pb,
10% Pt, 10% Sn, 9% Cd, 43% Ir. This material was left over from a jewelry manufacturing school. The only rate that I have found so far is a 33% payout on the Ir and 92% on the Pt. If you know someone or can be of any help can you please PM me?

lowgrade,

I don't mean to offend you, but that just doesn't make sense. I can't imagine why anyone would combine these metals.

You say it's left over from a jewelry manufacturing school. Not a manufacturer, but a manufacturing school. :?:

Even if we assume it's a big mixture of leftovers all melted together, why is there 9% cadmium? And why is there 10% platinum? And 43% iridium??? But no gold, silver, copper, zinc... anything we might expect a jewelry manufacturing school to use to teach jewelry manufacturing.

I'm sure there's more I don't understand?

I would be a buyer but the likelihood of the material actually having iridium is minimal for several reasons:

1. Iridium is very poorly soluble in lead (even used in separating from other PGMs, which are much more highly soluble)
2. Lead and cadmium would volatilize at that high percentage of iridium (even if a eutectic existed, it would probably still be above the boiling point of Cd)
3. This would be a tremendous quantity of iridium.

Who did the assay? XRF is meaningless on this type of material.

The specific gravity should be well over 16 g/cc. Iridium is unlikely to be dissolved in the melt but would be present as a recrystallized mass, separate from the platinum which reports to the lead. If they're offering you 33% on the iridium, it's because they'll get 50% and that they probably aren't refining it.

You very well might have platinum.

Sorry :/

It's ok guys. I am just going off of what one of my customers has told me. I do not know who did the assay. This might be one of those he said she said deals. I think what I will do is have him ship one bar and do a assay myself to find out what is really in here. You are right Lou, thanks for your help.
