I need help trying to figure out the best way to recycle the gold from these mirrors. I have a total area of 376 square inches on seven octohedral mirrors. I am guessing electroplating since the ends have some gold but not a lot of course. I don't want to use anything to caustic if possible but most of all I need it to be something i can do in an apartment or if outside it cannot take more then a day. I would love to use something that would eat the aluminum if possible since it would leave the eight slabs of gold from each mirror. They are around 5" tall x 3.5" thick with a stainless steel rod through the center that supports two bearings and a magnet. They came from the Accu Sort DM-3000. I have searched everywhere for info on these since they are worth more then the gold no matter how much I obtain. I know the original machine price included $1000.00 due to the single mirror in each machine back in 1996.
Thanks for any help.
