hello, thank you for having me... i'm portuguese and i've been scrapping boards for a couple of years and stockpiling components, i've watched many many hours of gold refining on youtube, i think i have the theory, but never got the guts (and some of the chemicals) needed to give it a try... i found this forum bcs i have some questions about if its worth keeping some especific components, but i'm gonna make a deep dive in the forum and if i cant find the info i'll make a thread... thank you.
