ABSTRACT OF THE DISCLOSURE An improved process for effecting fluid-solids contacting under fluidization conditions wherein a bed of suspended magnetiza- ble particles are contacted in a contacting chamber with an oppos- ing fluid stream which passes through the bed in an ascending manner. The bed is structured or stabilized by an applied magnetic field having a strength sufficient to suppress solids backmixing. The bed of suspended magnetizable particles is passed in a descend- ing manner substantially countercurrent to the contacting stream and removed from the contacting vessel. The process is operated in a manner such that the ratio of the difference between the transition velocity and the operating velocity to the difference between the transition velocity and the normal minimum fluidization velocity ranges between -0.1 and +0.5.
