Please excuse me if i don`t understand quite what you mean...but sounds intristing enough to find out more about this process of yours.
Can you please tell me, exactly what material you use this process for.....schredded PCB?....Various mix of IC chips?....Pins,connectos,MLCC mixture?.....Ceramic IC?.....or the mixture of all materials whatsoever?...
I separate my materials on grade, if i dont sell as a whole board...so if i was to use this termite method of yours, what material is ideal to use this proces without contaminating my results with unwanted metals?
I am not a chemist, nor a metallurgist expert, that is why I ask, since you obviously have more information/experience on this topic...
Thanks..
Pete
