I work for the local telephone company.I have collected alot of old scrap boards but only the ones with gold pins on them.I have cut off the gold pins and I am in the process of refineing them with a formula I bought off of ebay. I have access to alot of boards like this that the phone co. throws away regularly.Is there any way that anyone can tell me what I can get out of these boards(as far as metals) and if so by what methods.I am a beginner but I am very interested in this.Any anwsers will be a great help.
