Gold beneficiation process: first use the transverse chute to recover coarse and medium-grained gold, then use the rougher jigger to recover fine-grained gold from the tailings of the transverse chute, and then use the jigger and shaking table to select the crude concentrate, and finally use the amalgamating cylinder to extract the gold. Production practice shows that: it is best to install dewatering device before rougher jigger, so that the concentration of the tailings in the horizontal chute is suitable for the jigging operation requirements. The total recovery rate of the gold mining ship is 75-80%, of which the gold recovery rate of the horizontal chute is 52-55%. The roughing jigging is 23-25%. Main equipment: Cylindrical screen specification ¢2.7*10.8 meters, inclination angle 80, the screen hole is divided into five sections, respectively 8.10.12.14.16 mm. The water pressure inside the screen is 45 kPa. Jigging machine is JT type double chamber jigger, total 10 sets, jigging machine operating slurry concentration is 40-60%. The shaking table is 6--S type. The amalgam cylinder is ¢480*600mm. One time loading 50 kilograms of material, mercury mixing time is 1.5 hours.
