![]() 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. This mat should be used in addition with other Gold Hog brand mats.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). Not recommended for slow water stream sluices because there is just not enough "energy" to get the proper exchange flowing. The Bedrock Mat was new for 2013 and is a hybrid mat designed for higher water speeds, and has the ability to separate out even super fine gold down to -200 mesh material.Varying surfaces such as this is the key to great gold recovery! The drop chambers and the pre-ramp grooves catch gold even before it hits the riffle. This mat has a very aggressive face pattern that uses a large riffle to cause traditional flow interruption vortexes. The River Hog Mat (down draft) is designed for dredges and commercial operations, although it also works great in a wide variety of equipment such as a mini highbanker. ![]() It uses Micro Riffles to create low turbulent vortexes that do not throw fine gold back into faster moving upper currents. the Razorback) is designed to work in a wider range of sluices, including stream sluices. The Gold Hog Medium Velocity Mat (a.k.a.This patent-pending mat is made from extruded EPDM rubber and is heavy, durable, and able to withstand commercial sluice boxes in all temperatures. the Wild Boar) is designed to help break up clay and dirt, releasing gold and heavy metals. The Gold Hog Low Turbulence Scrubber Mat (a.k.a.It is made from extruded EPDM rubber and is heavy, durable, and this patent pending mat is able to withstand commercial sluice boxes in all temperatures. It performs the best with water flows over 1,000 gph and is desgined to be an under riffle, under expanded metal sluicebox mat. The Gold Hog Under Riffle Mat is a multi-function "active" mat that constantly exchanges materials for heavier ones.If you're looking for BIG performance in a small package, this classifying highbanker / trommel is for YOU!
