While cleaning out an abandoned storage unit I won at auction I came across a bucket with remnants of circuit boards that had obviously been through a chemical bath for the removal of gold. Coincidentally I researched this process a couple of years ago via You Tube thence my recognizing what It was I had discovered. Long story short there was/is a separate bucket (approximately 1.5 gallons) filled with a gold/yellow liquid which presumably is aqua regia or a solution that's ready for the gold precipitation process so what do I do now?
