Again, on 2.5 mm to 1 mm gold the jig was 90% effective, and the efficiency decreased rapidly as the particle size decreased. On 100 micron gold it was still 50% efficient, though, much better than a sluice for particles between 1 mm and 100 microns. The above jig will process 1,000 to 2,000 pounds per hour of -1/8" ore.
