Introduction - Stanford University

A water sluice is a gold mining technique. Crushed ore and gravel are mixed with fast moving water and then channeled over a long trough with a series of perpendicular-to-the-flow slats. Each row of slats gets smaller as the water flows longer in the channel. Since gold is heavier than the surrounding rock, the gold nuggets collect at these slats.
