4Plex gold roughing jig

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 finishing jigs or a roughing table. Finally, perform separation across the Xtruder table.
