Lead is often overrepresented in XRF analysis because it shields the x-rays of the other elements, a layer of lead oxides on the surface can make it worse maybe that’s the issue here?
Good point, but I doubt that's the main issue here, the analysis was performed on one rock, wich was crushed completely and then messured using a stationary WDXRF, which is much more precise than the handheld energy spectrum scanning version. The 5kg sample comprises of approximately 200 individual rocks, and by just picking one of them the sample might not really represent the batch as a whole. Also the 5 pieces picked for electrolysis might be the culprit in that they all where just a worst case piece of ore. Im excited for the final ammount of lead, so that we know an exact figure for the percentage of the whole bucket.
How to turn your house into a hazardous waste site. At the temps needed to smelt lead it's somewhat volatile especially the oxides that form on its surface.
That's why melting lead also has to be done in a fume hood. However, the amount of hydrogen sulfide produced here is probably more worrisome than the actual lead.
Very cool ! metals extraction from ore is always interresting
Cool process and analysis! Excited to see more.
It's so shiny when it was that lil button you can see the reflection of the torch as it is forming.
Excellent.

A question if soil has sulfur in it how to get rid of it
