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. The sluice box is bolted to our sturdy stand for additional strength and the legs are easily adjusted for uneven terrain.ħ) Highbanker Pressure Hose: 1.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). Our extensive use of Nomad matting and triple classification makes for an unbeatable combination. Threaded caps allow for easy removal of any debris that passes through the pump, and the grizzley is easily removed to simplify cleanups. The unit is equipped with a large hopper, containing two spraybars, each with two rows of holes to ensure complete washing of dry and/or clay-bound gravel. In addition, the HP100 is the perfect size and operates at the proper RPM to develop peak water volume and pressure required for optimum performance. There are some obvious advantages that come with using this engine: the famous Honda quality, low oil shut off, and the ease of no longer having to worry about those gas and oil mixtures. It’s powered by our HP100 pump, which is direct coupled to a Honda GXH50 engine, offering out standing performance.
