What does Dredging Consist Of?

Dredging is an excavation process or operation that is normally done at least to a certain degree under the water and this is done in shallow seas or fresh water areas with the intention of gathering up bottom sediments and disposing of them in a different area, generally to maintain channels passable. A dredge is a machine that is utilized for scraping or sucking the seabed and is used for dredging. A large dredger consists of a ship or boat that is set up with a dredge. The method of dredging makes spoils or the excess material, which are taken to a different place from the dredged area. Dredging can generate materials for land reclamation or other functions, and has obviously in addition traditionally played an important role in gold mining.

Dredging with suction pumps
When this process is carried out the auriferous material that is to be processed is dug up and elevated from the bottom of the river with a centrifugal pump. The pump is mounted on a platform and the mouth piece of the suction tube is held and guided by a scuba diver that works on the bottom of the river who takes care of placing the tube on the sands that are going to be suctioned. The air for the scuba diver is provided by an air compressor. The auriferous material is transported from the bottom of the river by a pipe towards the drainpipe on the platform or on the surface. The success of this operation is obtained when there are not any bigger sized rocks, tree trunks, wood, and clay and when the river is not too deep and when it does not rain. The suction tube is of one diameter of 4 inches to 6 inches, the water and material auriferous relationship is difficult to regular.
