Alluvial/Placer gold deposits are gold-containing sand-mixed sediments formed after long-term weathering of vein gold deposits.Alluvial gold mining means mining from land surface or river or underground. Gold is in a free state in the sediments, and the difference in specific gravity between sand and gravel is obvious.

The methods used to mine alluvial gold deposits in Western America during the gold rush have been known for centuries. These included using the well-known gold pan (batea), the rocker box (or cradle box), the Long Tom, and the sluice box. Each device was a refinement of the previous one. For example, a rocker box handles finer material better than
