Gold Dredge Equipment
Name: Gold mining dredges, gold dredges, gold mining ships, gold dredging equipment.
Scope of Application: Riverbends, banks of rivers and streams, river mouths, the base of waterfalls, reservoirs, and shallow sea basins.
Main Gold Dredges: Small gold dredges (small suction machines) and larger gold dredges (bucketline dredges).
Gold dredger is a kind of water-based joint plant integrating mining operation and ore dressing operation, which is mainly used for mining alluvial gold ore. The gold dredger is a kind of gold mining ship and a kind of deformed product of sand dredger, and the gold dredger is also called a gold mining ship in some places. Raise the sand outlet of the sand pumping ship to leave the space for adding gold mining equipment, laying mineral processing equipment, and so on to become a gold dredger. It is suitable for gold mining operations in rivers, reservoirs, and shallow sea basins. In addition to being used as gold processing, sand pumping, and gold dredge can also be used as platinum and diamond washing ships.
Classification of gold dredge
From the beneficiation process, the gold dredge is divided into a fixed sluice box, stirring/wriggling sluice box, vibrating gold sluice, automatic discharge sluice box, water jacket centrifuge, jig separator, and other types.

Bucket Chain/Ladder Gold Dredger
The bucket chain gold dredger is a highly efficient mining equipment used for gold extraction from riverbeds, lakes, and shallow sea areas. It uses a continuous chain of buckets to scoop up sediment from the bottom, then processed onboard to separate gold from the waste material. The bucket ladder gold dredger has high recovery efficiency and is designed to recover fine gold particles and larger nuggets. It can handle varying capacities, from small-scale operations to industrial setups.
Advantages
- Efficient for large-scale dredging and gold recovery.
- Suitable for alluvial gold mining in shallow waters.
- The continuous operation ensures higher productivity.
- Can operate in remote locations with appropriate power sources.
Applications
- Alluvial gold mining in rivers and streams.
- Gold recovery from sediments in shallow seas or lakes.
- Cleanup operations in tailing ponds or old mining sites.
