The utility model discloses an ore slurry level lifter. The ore slurry level lifter comprises a first slurry storage box, a second slurry storage box and an air compression device, the lower portion of the first slurry storage box is provided with a slurry outlet, the upper portion of the first slurry storage box is provided with an air inlet, the vertical separation distance between the air inlet and the slurry outlet ranges from 80 centimeters to 130 centimeters, the slurry outlet is communicated with the second slurry storage box, and the air exhaust end of the air compression device is connected with the air inlet. The ore slurry level lifter is ingenious and reasonable in structural design, air is led into ore slurry, the viscosity of the ore slurry is reduced, flowability of the ore slurry is improved, and a good conveying effect is achieved; meanwhile, compressed air exerts force on the ore slurry, the height difference between ore slurry levels is increased, the ore slurry in one slurry storage box is conveyed into the other slurry storage box, reliability is high, stability is good, the service life is long, it is detected that the service life is about eight years, equipment maintenance costs are effectively reduced, and benefits are obvious; in addition, the flow of the ore slurry can be adjusted by controlling air pressure, operation is convenient, and wide popularization and application are facilitated.
