Alluvial Gold Mining - CDE Global
Alluvial Gold Mining. Alluvial gold is found beneath the surface at the bottom of a creak or stream. Alluvial gold mining is the process of extracting gold from these creaks, rivers and streams and is generally considered to be the most environmentally friendly method of gold mining as a result of the reduced environmental impact when compared to underground mining.
