Placer Gold Mining Basics

Gravity separation remains the most widely used recovery method to extract placer gold. Gravity recovery equipment, including gold pans, sluice boxes, long toms, shaking tables, jigs, and amalgamation devices, have been used since the time of the California gold rush, and many present day operations still employ the same types of equipment.

Finer screening, to further improve fine gold recovery and reduce water usage, would have resulted in even greater gold losses. Another extremely important point in this regard is that coarse placer gold commands price premiums in the jewelry and collectable markets.

Prospecting Placer Gold Deposits

Prospecting for placer gold, except perhaps in the case of buried placers, is the simplest form of prospecting. Gold, platinum, and tin are the principal metallic minerals won from placers, but gold (alloyed with varying percentages of silver) is the only metal that has been recovered in commercially important quantities from placers in the United States.
