This process is repeated in each of the Gold Cube's separation trays. In mining, the low pressure zone behind a riffle— in a sluice or dredge— is called an eddy. The eddy rolls horizontally and the vortex churns vertically like a tornado. The vortex is the tornado effect that stirs up the dirt. The material churns and is really soft in the water, so the gold sinks to the …
