Gold: History of Use, Mining, Prospecting, Assay & Production
Early Gold Finds and Production. Gold was produced in the southern Appalachian region as early as 1792 and perhaps as early as 1775 in southern California. The discovery of gold at Sutter''s Mill in California sparked the gold rush of 1849-50, and hundreds of mining camps sprang to life as new deposits were discovered.

Fine Gold Recovery. Separating Placer Gold Particles from Black Sands.
Recovering fine gold from black sands is one of the most challenging aspects of gold mining. While we are all hoping to find that once-in-a-lifetime gold nugget, the vast majority of gold that we find as prospectors is very small in size, ranging from gold flakes down to dust so small that it is nearly invisible.
