Did anyone try to melt (not smelt) the crushed, pyrolyzed pcbs in copper collector?
I would try this if i had furnace already... But unfortunately i havent built it yet.
My theory is that all the junk will flow on top of copper, so if you stir feed well while submerged in molten copper, the values should absorb into molten copper. And after the process one could easily remove fiberglass and junk like steel.
The slag and junk could then be gravity concentrated and fire assayed for finding out efficiency, and losses.
The reason why i am thinking about melting with copper is that i dont like idea of adding more material (flux) which might hold values if done incorrectly, also its kinda hard to source them low scale.
I understand its just wishful thinking... And smelting is done for a reason....
But any input would be appreciated.
My main concern is that copper would adhere to fiberglass, and crushed steel case components not melting properly in the copper melt.
