The keyboard mylars the clear plastic sheets the traces are applied using a conductive ink made from silver, if you get enough of those mylars just pass them through a cheap paper shredder a couple of sheets at a time.
Place the shredded plastic bits into a rock tumbler dry and the silver ink will soon abrade free of the mylar, wash and rinse saving passing the water through a coffee filter - now you have your first silver.
Many years ago a bud of mine went on a road trip, somewhere in Hudson Hope he had abandoned his 56 Hudson Hornet after the automatic transmission gave up the ghost.
I'm a fan of Hudson cars and early pick up trucks, fist car owned was a 47
