A fine powder air fluidization magnetic mesh screening magnetic separator comprises a fluidization feeding system, an annular electromagnetic generator, a rack, a magnetic separation working system and a discharged material collecting system. The magnetic separation working system main body device is provided with a plurality of magnetic separation screen bodies which operate in parallel and independently, and the magnetic separation screen bodies are provided with micron-sized high-permeability screens as magnetic separation media. In the period of discharging tailings through magnetic separation, magnetic particles are selected from fluidized powder one by one through micron-sized high-gradient magnetic grids, a powder interception layer on the magnetic grids is subjected to mechanical vibration force, ultrasonic vibration force and rotary brush stripping force, magnetic aggregates are opened to release non-magnetic particles, the non-magnetic particles are released and discharged, and the concentrate purit
