Scrap Circuit Board
anyone know of good online resources for scrapping precious metals off old circuit boards etc?

anything short of a community college metallurgy class thanks

I don't know of online resources, but acid digestion is the best method at this point in time, though a Dr Majorie Valix at the Unviersity of Sydney has some PhD projects currently running on using baterial digestion of metal trace from circuit boards to environmentally friendly recover the heavy and precious metals.

Thanks for stopping by our website we hope you found the Scrap Circuit Board you were looking for.
