Fine Gold Recovery Separating Placer Gold Particles From
Recovering fine gold from black sands is one of the most challenging aspects of gold mining. While we are all hoping to find that once-in-a-lifetime gold nugget, the vast majority of gold that we find as prospectors is very small in size, ranging from gold flakes down to dust so small that it is nearly invisible. Extremely fine particles of gold like this can be very difficult to separate from ...

Dealing With Black Sands Getting All The Gold Out Of Your
The trick is to make the magnetite and hematite jump up through the water to the magnet leaving the gold behind. Remove the black sand that sticks to the magnet and repeat. Eventually, when nearly all the magnetic minerals are removed, you can stir the magnet through the remaining sand in order to pick up as much of the material as possible.
