Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging.
These challenges are especially tough for placer mining operations. Even large companies have almost completely abandoned efforts to set up large placer mining operations within most of the U.S. Placer operations present particular challenges most associated with the fact that many of the gold-bearing rivers in the West are designated as having salmon and steelhead.
Whether mining permits are required should be investigated, because placer operations of any size may drastically change the local water quality. A simple operation may have virtually no effect on a stream or surroundings, but when materials amounting to more than a few cubic metres a day are handled, the possible effects begin to become significant.

Placer mining can be as simple as using a shovel and a gold pan in a creek. On a placer claim, hand-mining a deposit of any size usually involves a sluice box or highbanker, and a water pump . A machine-digging operation generally uses a backhoe or larger excavator and a more sophisticated "wash plant" for processing - separating the gold from the pay dirt.
Before a placer mining operation can begin, the first task is to identify where drainage has deposited gold into sediment layers. To locate a deposit, prospectors use pans to evaluate the surface materials.
