What is the best way to separate extremely fine gold from sand ... - Quora
First, pan the sand. If you don't have an actual gold pan, use a pie tin. Put a handful of sand in the pan, along with some water, and slosh it around. Allow the lighter sand to slosh out. You will start to see a small amount of black stuff in the low spots. That's magnetite, or "black sand." Keep sloshing until you have only black sand.
