How to Separate Gold From Black Sand: Complete Guide!

Black Sand Magnet. If you have concentrated your material down to just black sand and gold, a magnet could be of great help. Since black sand mainly consists of magnetite and hematite, which both are magnetic, a magnet can be used to attract the black sand and leave the gold behind. Now, just picking your old horseshoe magnet won't do.
