- Drywasher
-
The drywasher is a common desert mining tool. The drywasher is like a highbanker since it uses a motor and a form of sluice however it lacks the need for water. A drywasher operates by the use of air. By forcing air to flow up through the material as it moves down the sluice the heavier materials, like gold, will stay at the bottom and get trapped by the riffles while the lighter materials will flow up and over the riffles or be blown away. The lighterweight material that is not blown away will slowly flow down the sluice and fall out the end of the sluice.
