Extracting gold from computer parts (Part 2)

This is the second and last part. I totally messed up and forgot to talk about what to do with the waste. The metal waste can basically be recycled and used to clean more PCBs. I don't think I will do a video on this though.

Very nice! I have told our techs to put all old boards in a bin for me. Now - where to buy 20L containers of Nitric Acid... etc.

I would actually use the bleach/Hcl method over aqua regia. Works just as well and is a lot cheaper
