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 can be loaded with
