The automatic ore discharge centrifugal beneficiation machine is currently the latest type of gravity beneficiation equipment. The principle of the automatic ore discharge centrifugal beneficiation machine equipment is to use centrifugal force to expand the gravity of mineral particles to separate heavy and light particles. The key component is a conical enrichment cone, which is driven by an electric motor to rotate at high speed and surrounded by pressurized backwash water. The materials entering the centrifuge for separation are usually the minerals ground by the ball mill or the overflow slurry of the Hydrocyclone. The slurry is injected from the upper end of the enrichment cone to the bottom of the enrichment cone. There are rows of grooves formed by ribs inside the enrichment cone. The centrifugal force generated by the rotation of the enrichment cone will throw the minerals to the groove, Only heavy mineral particles can overcome the resistance of backwash water and remain in the groove to form concentrate. Light minerals, due to the small centrifugal force they are subjected to, are difficult to overcome the effect of backwash water. They are washed out of the groove by backwash water and overflow from the upper end of the enrichment cone under the continuous injection of water, becoming tailings.
This automatic ore discharge centrifugal concentrator has obtained an invention patent in China. The automatic ore discharge centrifugal concentrator equipment has significant effects on individual gold of different particle size ranges, especially for the individual gold lost during the beneficiation operation of other gravity separation equipment (such as gold slide blankets and jigs). This equipment can not only be used for placer gold mines, but also for recovering natural gold from rock and ore, replacing the mixed mercury extraction method, and can also be used for recovering gold from tailings. Through mineral processing experiments, it has been proven that the recovery rate of placer gold is over 99%, and the selection ratio reaches 1000 times. Especially when recovering natural gold from vein gold deposits, when the grinding particle size is less than 0.074mm, the recovery rate of single gold can reach over 98%, and for single gold with a size of 0.04mm, the recovery rate can reach over 97%.
