DryWashers for Gold - Gold Fever Prospecting

Dry-Washing for gold goes back to the earliest days of gold discovery, where water was not available to separate the valuable minerals from waste sand and rock. The early miners devised crude methods of utilizing the flow of air and vibration to concentrate and separate valuable materials like gold and gemstones from.

The Dry Washer -

Dry washers are most popular in areas where water is not available, such as dry washes and desert areas. A dry washer utilizes air, vibration and static electricity to very eff e c t i v e l y separate gold from the waste gravel. The use of vibration to move mate- rial through a sluice box is similar to the same movement created.
