What is a river gold dredger

The placer gold panning ship refers to the ship that mines the sand gold at the bottom of the river. The ship has the function of mining, extracting ore dressing for the placer gold or other minerals at the bottom of the river. The working principle of the gold panning ship is to first extract the mineral material from the river bottom. This extraction method There are many kinds, there are chain bucket extraction, sand pumping extraction and twisting suction extraction. The type is selected according to different river channels and different river bottom conditions. The extracted ore inevitably contains other wastes such as pebbles, and then Screening is required, and this set of processes is carried out on board. After screening, the gold-containing ore will enter the chute, or centrifuge, or jig for gold selection, and the waste will be discharged to Hanoi, or transported Go. If you want sand, you can also sell a piece of sand for construction. You can directly transport the sand to the shore or directly to the transport ship. This is simple and trouble-free, with low investment costs and high returns.

Gold dredgers are widely used in gold mining in rivers and reservoirs, with a large working area, unlimited river depth and reasonable structural design. It also called Gold digging ship/ gold dredging ship/ gold panning ship/ gold panning equipment/gold placer equipment/gold selection equipment/gold placer equipment.

Equipped with agitating chute, Nelson centrifuge and professional fine gold recovery equipment, the recovery rate of fine gold/coarse gold is as high as 85%-96%.

The ore processing capacity is 50-600T per hour. Diesel engine or generator set power 15--720kw, Hull length 10--90 meters, hourly water flow 80--600 cubic meters.

The equipment comes with double floating body (hull), mining system, screening system, washing system, working power diesel engine or unit, reducer, self-moving device, etc., with high degree of automation, energy saving and labor saving.

Hull specifications can be designed and customized according to the depth of the river and other requirements, and the depth of excavation can be within 40 meters.

The whole set of equipment can be designed and customized according to customer requirements.

It is a scientific, advanced and applicable alluvial gold mining and beneficiation equipment at home and abroad.

Diamond, iron sand, tungsten sand, tin sand, zircon and other heavy metal recovery devices can be designed according to customer requirements.

1. Several issues need to be clarified when purchasing a gold panning ship

1. Water depth, sand layer thickness, stone size, proportion, processing capacity, and other local special geographical conditions.

2. Selection of gold panning boats: jet-suction gold panning boats, cutter-suction gold panning boats, and chain-bucket gold panning boats.

  2. Overview and working process of the gold panning ship

Alluvial gold is mainly concentrated in the sand-stone mixed layer of the bottom river bed, and sandstone and gold must be washed and separated through multiple sets of procedures. At present, the main gold panning tools used are gold panning boats. The gold panning boats have been professionally designed. The large gold panning boats are also specially equipped with alluvial gold automatic cleaning devices, which can directly hit 80% of the purity. The recovery rate of joint operations is as high as 90%.

A gold dredger, also known as a gold dredger, is a water joint factory integrating mining operations and mineral processing operations. It is a kind of placer gold mining equipment, which includes excavation systems, mineral processing and water supply systems, waste ore and tailings discharge systems, and decks. Several basic systems such as machinery, hull, upper steel structure, and power supply.
