Gold dry washers are used primarily in areas where water is not available, such as arid and desert areas. 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 sand and gravel.
Modern improvements to the gold dry washer make drywashing for gold far more practical and efficient than ever before. Many prospectors even say drywashing rivals more traditional wet prospecting methods like sluicing, highbanking, and dredging. They may have a point, as you can be sure the dry desert areas have been far less worked than the rivers and creeks.
