Hi,
A friend of mine had a gold bar tested with XRF (Olympus Xpert) with the results showing 99.70% Au and 0.30% Ni (both +/- .01).
I know very little about the refining process, so the results seem odd to me. With the 99.70% Au, I would have expected to see other elements in there, like copper. Does this seem normal?
