Step 6: Pan Out Your Concentrates
This photo shows me panning out the black sands at home after returning home from Arizona. I pan them a few teaspoons at a time in a tub of water. I use a second pan in the bottom of the tub to catch the sand so I can pan through it several times and get out every bit of gold. My gold pan has riffles cast into one side of it which is very handy for this final stage of panning since they are really good at catching gold. They aren't absolutely necessary though. With care and practice, you could do it with any kind of pan. Once I get rid of the bulk of the black sand by careful panning, I use a powerful magnet inside a plastic bag to get the rest of the black sand out of the pan. Black sand is mostly magnetite, an iron mineral that is magnetic, so it will be attracted to a magnet. The magnet from a large speaker or from an old hard drive works well for this. Just remember to always use it wrapped in a plastic bag. Otherwise you will never be able to get the black sand unstuck from it. Once there is almost nothing but gold left in the pan, I suck it up with the sniffer bottle. Several times I have been surprised to find fairly large "pickers" in the pan that I somehow missed in the field. There will always be lots of little tiny bits of gold too. I always pan through the black sand several times until no more gold shows up. Panning into a second "safety pan" makes it easy to re-pan the concentrates as many times as you want to.
