High-pressure air is introduced into the air lifter through a central air pipe. The density of the slurry in the pipe decreases as air enters, creating a pressure difference between the slurry in the pipe and the slurry in the tank. Under this pressure, the slurry is lifted to a higher elevation. Air lifters are commonly used in mineral processing and cyanide production, leveraging excess air sources to transport slurry, which reduces power consumption and minimizes wear on components. Compared to sand pumps, air lifters save significant equipment and maintenance costs.
