Non-Chemical Molten Lead Panning??

[NoIdea]

Just a quick note I was doing some reading this morning and saw this bit on lead refining and thought of your post. Here's the link if you want to give it a look.

It mentions the way that they are refining lead and recoving their PM with the Parkes process and it got me thinking about this thread again so I thought I would share.
By the way I did try adding the gold foils into the bismuth like Butcher mentioned above and it alloyed into the Bi at around 750F. I proved it up with a XRF check of the surface finding the Au not perfectly alloyed but certainly present throughout. I have not cupelled the Bi yet as the Au is less than 1% so I am going to run some black sand through it first to try and add some fines and eliminate the black sand and what I believe to be zircon sand that is better at staying with the Au than I am at panning. I hope to get the Au to at least 5% before cupelation. So now I have to start looking into the next steps. I am going to put the whole experiment into a new post when I get the results.

All the best,
John
