Thank you for the response. My platinum is obviously not pure . Did you read my latest posts about the cadmium in it? It is indeed polymetalic. I do not expect the same appearance as your refined platinum.
Once again, who are you replying to.Thank you for the response. My platinum is obviously not pure . Did you read my latest posts about the cadmium in it? It is indeed polymetalic. I do not expect the same appearance as your refined platinum.

So who did you ask?Okay
The post I read said the xrf showed Cd with no percentage...not sure what that means except maybe no Cd.Thank you for the response. My platinum is obviously not pure .

Thanks Steve for the advice. All that I can tell you is that it contains platinum gold and cadmium plus nickel is likely since I have picked up nickel in this area with my White's coin master.A late silversmith tested palladium on claims that he had in the area so I already knew that it was here and it had to have come from this deposit. I have enough background information on this to proceed. I lost 8 months here trying to solve a couple simple problems it seemed of a better flux recipe and a hotter furnace but nobody has helped me with those things except for Kurt and that was just recently. I don't have any more time to keep repeating myself so I am not going to respond again until I get the test results and get paid. I am dieing and that 8months cost me more than you know,The post I read said the xrf showed Cd with no percentage...not sure what that means except maybe no Cd.
The latest photo looks like a small pile if Ag shot. It's much too white to be Pt. Admittedly it's very out of focus.
I was referring to your photo of the buttons on the scale.
Again, I would advise testing a very small sample before smelting a bunch of ore. Once you can prove Pt, not just believing, then press on.

This is sage advice, no matter what color the metal is, however...NONE !!!!! --- if it is PGM metal - like gold it will be bright & shiny !!!! --- & it will remain bright & shiny no matter how long it has been in &/or exposed to the environment

Hi I have something similar??This is apparently PGM that was separated during smelting at 2300 degrees for 3.5 hours in my new 8kg crucible .I inadvertently separated it from the platinum leaving the highest MP metal fused to the lower half of the crucible which I believe is platinum. I will use my oxygen/acetylene torch to puddle it and make a nearly pure platinum button. Can anyone tell me which PGM has the native metal that is dull and ugly in appearance?

XRF is not the only type of X-ray spectroscopy.X-ray spectroscopy is actually XRF.
If they have the correct library and are properly calibrated and operated by skilled trained personnel,
they can be relatively accurate.
And fire assays do not tell too much regarding PGMs as I understand it.
If you want reliable information a NiS assay is needed, An ordinary fire assay can tell you some, but not the full picture.
I haven't determined which metal it was but only certain ones produce native metal from what I understand.Hi I have something similar??
Some items have reddish marks...others silver, it is pretty spectacular to be fair..
This came from transistors ashed for gold powder.
Did you determine what the PM was?

I don’t think a metal can be identified by appearance. Pick out from a short list of known alloys, maybe. Show someone a 95-5 alloy of any 2 metals — I don’t think anybody’s going to be right very often. Until it hits 4 nines, Platinum can go from very dull gray to bright white, depending on what the surface impurities are and the crystalline structure resulting from the alloy and melting/freezing conditionsThe post I read said the xrf showed Cd with no percentage...not sure what that means except maybe no Cd.

specific gravity is very easy to measure and corrolate with density. Pt is 21+g/cc. I’d be encouraged by a dense button, definitely if it were >15g/cc
