I have recently been recovering gold from pins that are plated. These are "springy" pins from circuit boards. My understanding is that when you find copper with "springy" qualities it probably contains beryllium.
After I have recovered the gold from my acid solution (I'm using Aqua Regia), I suspect that the waste liquid will contain beryllium in some form. Beryllium is so low on the periodic table that even aluminum will not displace it from an acid solution.
So, in dealing with the waste from refining gold plated pins that may have a copper/beryllium alloy can anyone provide some help on safely handling and disposing of the waste?
