Captures Gold Dust | How It Works | Gold Rush Nugget Bucket

The most common form of gold (and the hardest to recover) are the micron gold particles known as "gold dust". The good news is that "gold dust" can be found, to some degree, at almost any lake, stream, river or beach. In fact, we have even found small amounts of gold dust in bags of play sand purchased at the local hardware store!

Sand is measured according to specific parameters. If more than 50 percent of the material is larger in diameter than 75 microns (.03 inches) but smaller than .18 inches, it is said to be sand. If the average particle size is smaller, it is considered to be silt or clay, and if the average particle size is larger, it is garden-variety gravel.
