![]() ![]() Plus, advances in technology allow a small surface gold dredge to be carried by a single person to a remote stream or river and profitably process gold-bearing material.Ī suction dredge used along the shoreline works like a large vacuum cleaner by sucking up underwater gold-bearing material like rocks, gravel, sand, and dirt and forcing it through a highbanker or power sluice that is capable of recovering very fine particles of gold. ![]() Sandy or gravel river banks contain large deposits of alluvial gold (loose pieces of gold or gold-bearing sand), and dredging is a great way to recover this gold. These pontoon dredge pumps are suited for ponds and lagoons up to 20,000 square meters surface areas, up to 3.5 meters deep.Over the last 10 years or so, dredging has resurfaced as a popular form of gold mining (except in California where dredging is currently banned). The dredge pump agitates sediments and can pump up to 30% solids. The DAE Pumps pontoon dredge pumps remove sediments and slurry from tailings ponds, lagoons, and holdings ponds. DAE Pumps pontoon dredge pumps are easy to set-up and start running. These small pontoon dredges can be transported by a truck or trailer and deployed without heavy equipment. However, with DAE Pumps mini dredge pumps, this process can be completed internally to meet all environmental regulations. The facilities often outsource the maintenance to dredging companies. Power plants, paper/pulp plants, mines, chemical plants, oil fields, and other industries need to keep the capacity of their tailings and cutting ponds while following the environmental impact standards. Their designs are also poly, clay, or concrete liner safe. Ideal for lagoons, small lakes, basins, ponds, and other smaller dredging projects, these unique pontoon dredges are built with powerful, non-clogging pumps designed for high solids industrial pumping applications. The mini pontoon dredge and small pontoon dredge allow for one to two operators to run a dredge at high production rates. The DAE Pumps Pontoon Dredge Pumps are portable, robust, and smaller version dredges that are capable of dredging areas that the large dredging operations cannot access. ![]()
