Been meaning to post this but kept forgetting. Just for kicks, I had my assayer perform XRF on a slice of ore. Was curious to see what that fancy hi tech machine could do. Attached photo are the results, with sample slice. Had to crop out the portions with personal details on it.

It took less than 7 minutes and I was handed the results. As expected, no noble metals worth mentioning...but hey, copper's still money eh? The process is fast and cheap (the lab's been giving me highly discounted rates since I became a very regular customer) and the process is non-destructive. XRF is only suitable for samples which are more or less homogenous.

Wish that cupellation only took 7 min too, instead of the usual 2 day wait.

No Photo of the Sample?

Cool Beans, and Yes Fire Assay is much better.    It shows what can be produced from that sample.

Homefire..the sample slice is on the yellow paper, with the cut edge showing, about 2/3 of the way up vertically, and in the middle (between the words Element and Concentration).

I doubt I'll be using XRF any more...but it's amazing (at least to me) that an x-ray can detect and differentiate so many types of metals. Technology is truly wonderful.

If you have a thing going and getting it cheap, It sure would be good for stab and grab samples.
