This is another great option of the Underflow river sluice that runs screened material (right pic) to collect all your precious metal recovery needs. This system is ran by the natural flow of water by placing the Underflow river sluice in the water current at a 5-10 degree angle depending upon size of material being processed through the sluice (keep slickplate slightly higher). Start running material by putting pre classified matieral on the top of the slickplate. If classifiers are desired (left pic) increase waterflow and angle 10-20 degrees , you will notice the unwanted material passing over the classifiers and heavies going through the classified screened plates (double classifier sizes are buyers preference) and processing through the adjustable 1 1/2" underflow traps collecting all precious metals within the collection traps. This will gather all gold, precious metals, and gemstones down to... Yes, even micron metals. The wider the underflow river sluice the more material it processes, and works like a dream. Less work equals more gold!
This includes the three traps and the slickplate no classification
