The first stage in alluvial gold mining is to take the dredged river bed material and separate the small sand faction (where the gold is found) from the larger mineral fraction. In a typical alluvial mining process physical separation methods such as screening and gravity separation are employed to separate the gold from the mineral fraction.

This kind of mining is generally not considered acceptable because of the high impact on the environment. However, there are other tools gold miners can use. One of the more popular ways to mine rivers of alluvial gold today is the gold dredge. These can vary in size from a backpack unit to great floating barges the size of hotels.

2021-5-1 In addition to the under level in our deepest and most difficult alluvial mines, an upper level should be constructed in the bed-rock, for three very important reasons. First, to provide an escape for the men in case the mine should be flooded; secondly, as a return air course; thirdly, to tap the water by boring, at a higher level, where the pressure would naturally be lightest.

Alluvial Gold (Deposited by water movement) and Eluvial gold (disintegration of rock at the site where it originates - not there through water movement) are essentially primary gold broken down by weathering and erosion and transported by gravity or water movement over many millenia of geological time.

2016-8-17 - high capacity (alluvial mining) - local production - no motor no moving parts - easy operation - good recovery even for fine gold (if properly built and operated) - high enrichment ratio - good for cleaning of amalgamation tailings Disadvantages: - needs much manual work, security problem - does not completely recover sulfides in primary mining

2016-10-26 Since a steep grade, a rapid flow, and deep currents are best suited to effect speedy and thorough disintegration of the gravel, while a low grade and slow and shallow currents are best adapted for saving the gold, the upper part of a sluice, for a sufficient distance to effect the complete disintegration of the gravel, is sometimes made of higher grades, or with narrower boxes
