The methods had been developed by the Romans in Spain in 25 AD to exploit large alluvial gold deposits, the largest site being at Las Medulas, where seven long aqueducts tapped local rivers and sluiced the deposits. Spain was one of the most important mining regions, but all regions of the Roman Empire were exploited Alluvial Exploration Mining,The tropical alluvial deposits (placers) are saturated with water. Floating dredges are used to mine alluvial deposits. This type of exploitation is the least expensive method of mining. The operational cost is 0.1 to 0.2 mg/m3. Only few paleochannels are more than 50 feet (15 m.) deep. A mobile (floating) recovery plant also
