Application of Dredge for Purpose of Valuable Materials Collecting

The suction dredge is easy to operate by one or two individuals, making it quite popular in areas where raw gold is located. Generally, the suction dredge vacuums up sediment through a hose that is located on the river or creek bottom. After the sediment is suctioned to the surface of the dredge, it is processed and sorted through a sluice. The sluice is used to remove any valuable materials, while the waste sediment is typically discharged from the dredge.

Generally, the sediment is suctioned up from the bottom of a water body or buckets are used to scoop up the sediment. Dredge mining is the technique that is often used by commercial and recreational miners to collect raw gold. When dredge mining for gold, the dredge is used to dig, sort the materials, collect the gold, and discharge the unwanted sediment.

A screen and flume dredge is used to work with larger rocks, separating sediment from the larger materials using a screen that revolves. A table stacker dredge uses a series of buckets to dig up sediment and separate it from valuable materials through sluices.Although dredge mining has been used for centuries, there are some environmental concerns related to the technique.
