XRF is worthless. Please research it. But there is a substantial amount in the hands of a well-qualified institution, as well as other smaller processors who have been testing. The first tests were Iridium. I will grab those pics. They are quite different...Surely you have been here long enough to know someone will be asking if you have an assay or any XRF indication to justify the thread title!!!!
Well I have both. Initially it's hard to distinguish, but not anymore. Try it, not easy.Hmmm - on July 20 you were trying to sell rocks that looked very much like these as silver

Now they are PGMs

Hey Vinnie? Dis guy knows too much....Was that mobster ball mill used to dispose of the mobsters in New York and New Jersey?

Some of those rocks just look like polished hematite. I have some pieces like that myself.Per the bold print - & that is my point
container big enough to "soak" a rock but not big enough for specific gravity test makes no sense --- & even if he did a specific gravity test - it certainly wouldn't validate his claim
And simply being heavy doesn't validate his claim
IMO - snowdog20 is simply trying to sell something on his claim that it is what he claims it to be - but nothing to back up &/or validate that claim
IMO - it smells a lot like this --------

Love the BS filter Kurt. Smells funny to me as well.But then you say
So you have a container big enough to soak them in water/HCl - but not big enough to do a specific gravity test in ???
Lead is heavy to - being heavy doesn't make it silver gold or PGMs

Another forum user? Who? Can he back up your claim?I'm in Alaska, so long as I get funds by say 1630 my time (430 pm), I can ship today. I have another forum user who's making bars of Ag just like this also from me. I can have you chat with him.

Rudimentary, elementary and sedimentary - Maybe?Again: who? Are these pro's and institutions secret or don't they want a, well, lets say giant group of people who daily deal with precious metals and ore to know they can assay and test?
So give us some names and facts please, or get nominated for a ban. I have had about enough of you.
You are very vague and misleading imo.
I received your emails, and remain interested to find out about the assayed contents of your white metal nuggets, and ores, I just had a total hip replacement, so other than foundry and bench work, my field work is on hold. I also have one half ton of Benitoite ore and rough to process. I have photos of my nugget samples from my claims, maybe I'll post some in the future. I may in the future, offer to do fire and chemo assays myself. XRF serves a different purpose.Nuggets. Other members are .processing some now. Not polished, tarnish removed yes. PGMs have iron, chromite, etc. So, they get placed in water/hydrochloric acid for a bath. The reason large sizes is because the faults are quite big.
I must disagree with you. I work for few years, relying on daily XRF analyses. And when you measure bulk metal samples, there is nothing comparably efficient, quick and practical. It is not the determining tool like ICP-OES etc. or fire assay to exactly to one decimal minimum say you have this in here. But it serves me very well and to my knowledge, never failed in my hands when properly used.XRF is worthless. Please research it.

The XRF has changed the world of refining for those that understand it. And it has opened up the world to less than honest characters who want to exploit it and the speed it brings.And when you measure bulk metal samples, there is nothing comparably efficient, quick and practical.
I have come to appreciate the XRF for the speed it affords an analytical chemist to determine the best route for proper quantitative analysis.It is not the determining tool like ICP-OES etc. or fire assay to exactly to one decimal minimum say you have this in here.
Yeah, exactly as you say. To simply discover what the... is the sample sometimes took quite long. With XRF on PM mode and Geochem mode, you know quite precisely what matrix is in here and what PMs to expect.The XRF has changed the world of refining for those that understand it. And it has opened up the world to less than honest characters who want to exploit it and the speed it brings.
Back in my day, remember I'm old and a fire assay and gravimetric guy, analytics took days and many more samples just to determine a starting point for good quantitative analysis. The XRF changed all of this with quick results which, as Orvi understands,

They key word is metal (not ore).I must disagree with you. I work for few years, relying on daily XRF analyses.

I also heavily use Geochem mode, which is capable to read complex light-element matrixes like you have. But if it is in solid metal form, polish one side or better slice a piece off and measure it.
Without analysis, nobody will trust you.
