The LIPU Mini Gold Dredge is a compact floating system designed for small-scale placer gold recovery from suitable river sand and gravel. Depending on the selected configuration, it can include an engine, sand pump, floating platform, hoses, and a gold recovery sluice.
Its compact layout can be suitable for sites where larger equipment is difficult to transport or position. The right configuration depends on water conditions, feed material, pump requirements, and the required recovery setup.
A mini gold dredge moves water and gold-bearing sediment through a pump to a recovery sluice. As the feed passes over the sluice mat, some heavy particles are retained while lighter material continues out with the process water.
The feed arrangement varies by model. Add a screening step to the process description only if screening equipment is included in the selected configuration. A dredge concentrates heavy particles; it does not refine or purify gold.
Depending on the selected model, the system may include:
Confirm the engine type, float material, final component list, and included accessories for the selected model before ordering.
Recovery results depend on gold particle size and distribution, feed characteristics, water conditions, equipment setup, and operating practice. Actual performance should be evaluated under the intended site conditions.

Consider these factors when selecting a model:
Share the site and material details with LIPU so the proposed configuration can be checked against the application.
Operate the dredge only in conditions suitable for the selected model. Before use, inspect the floating platform, pump, hoses, fittings, and sluice. Secure the equipment, keep clear of moving components, and follow the engine and pump manuals.
Check local requirements for waterway access, dredging, sediment discharge, and environmental protection before operating. Site conditions and permitting requirements vary by location.
Support available for the selected order may include:
Confirm the scope and duration of service and warranty coverage in the quotation or sales contract.
What material can a mini gold dredge process?
It is intended for suitable gold-bearing sand and gravel. Feed-size and material limits depend on the selected pump and recovery configuration.
Does a mini gold dredge refine gold?
No. The dredge uses a physical recovery process to concentrate heavy particles. Refining or further cleaning is a separate process.
Does every model include a screen or trommel?
Not necessarily. Confirm whether screening equipment is included in the selected model before describing or ordering that configuration.
What pump options are listed for the mini dredge?
The current product information lists one 2-inch pump, one 3-inch pump, and two 2-inch pumps as configurations. Confirm flow rate, head, and operating depth with the latest LIPU datasheet.
What information is needed for a quotation?
Provide the site conditions, water depth, feed material, preferred pump arrangement, sluice requirements, delivery destination, and any local operating constraints.
We provide a variety of mining and processing equipment, including feeders, rock crushers, grinders, classifying and screening machines, washing machines, gravity separators, flotation machines, magnetic separators, electric separators, dewatering equipment and laboratory mineral processing equipment.
