Alluvial Gold Mining
Alluvial gold usually takes the form of dust, thin flakes or nuggets. 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.
Sandy or gravel river banks contain large deposits of alluvial gold (loose pieces of gold or gold-bearing sand), and dredging is a great way to recover this gold. Plus, advances in technology allow a small surface gold dredge to be carried by a single person to a remote stream or river and profitably process gold-bearing material.
