Basic Placer Mining for Gold learn about the equipment

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.

California Gold Mining Terms and Procedures 1876

A considerable percentage of the gold is lost in hydraulic mining, in great measure on account of the rapidity with which the work is prosecuted. Fine flour gold has not time to settle through the thick water, and is carried off in the tailings. IN California Notes, Chapter X, by Charles B. Turrill, San Francisco, E. Bosqui amp Co., 1876.
