When operating a wash plant using jigs, the typical process to achieve recovery rates of 90 to 98 percent should be done in a step down concentration method. The first step is to process ore through a roughing jig. Second step, process its concentrate through a cleaner jig. The third step is to process its concentration through our Enhancer or a roughing table. Then the final separation is processed across the Xtruder table.

Gold recovery is accomplished via gravity separation, which works extremely well because gold has a specific gravity of approximately 19 while sand and gravel have a specific gravity of approximately 5 to 7.

4Plex Gold Roughing Jigs

Gold Jig

4Plex Gold Roughing Jig Plant

Our 50-inch roughing 4plex gold jig with twin 36-inch cleaner jigs. The shown configuration utilizes gravity separation, our 50-inch roughing 4plex jigs, and twin 36 inch cleaner jigs underneath. This unit has a capacity up to 112 tons, or 75 cubic yards, of solid materials per hour. Its water consumption rate is 350 to 650 gallons, or 1325 to 2460 liters, per minute. The unit has the capability to recover gold down to 400 mesh, or 37 microns. A typical installation of this unit would be installed with one of our 200 tons per hour wash plants, because the jig only receives 1/2 inch or smaller material, which can be about 40 to 50 percent of the wash plant total input.
