Alluvial mining is the mining of alluvial deposits of precious metals, either in rivers and river banks, or in now dry ancient river beds. Gold deposits found in rock formations in the mountains and along the rivers, disrupted through erosion, are displaced via flowing water from rain and washed downhill and concentrated in streams and rivers.

Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant.The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate.
