These specialized tools are designed for separating heavier gold particles from lighter materials like sand and gravel, utilizing gravity and water. They are circular, shallow dishes, often made of plastic or metal, with riffles or ridges to trap gold during the washing process. Various sizes and materials cater to diverse user preferences and mining conditions.
Acquiring these tools represents the entry point into the hobby of prospecting or a necessary component of small-scale mining operations. Historically, such equipment facilitated the extraction of precious metals during gold rushes. Modern iterations continue to provide accessible means of gold recovery, offering recreational opportunity and, in some cases, supplemental income.
