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.
Alluvial gold recovery methods, mainly based on gravity separation combined with mercury (amalgamation), have been applied since the early days of mining. Historically, mining gold from the riverbeds was first …
