The riffles are designed to create dead zones in the current to allow gold to drop out of suspension. The box is placed in the stream to channel water flow. Gold-bearing material is placed at the top of the box. The material is carried by the current through the volt where gold and other dense material settles out behind the riffles.

Compressed air is used as an energy source frequently in mining because of its flexibility over the use of diesel and electric power in locations underground. However, low capacity applications such as drilling short holes, pumping and pneumatic tools such as wrenches and saws are more commonly used with compressed air systems at sites.
