We present experimental results for the magnetic filtration of magnetite fine particles using a high-gradient magnetic separation process as well as analysis based on a theoretical model. The experimental investigations were carried out using a superconducting magnet able to generate a magnetic field up to 6 T, to magnetize the magnetite particles and filter meshes. Comparing theoretical predictions by the particle trajectory analysis method against the experimental results, we concluded that the theoretical results are consistent with the experimental results up to a fluid velocity of 0.7m/s or a Reynolds number of 350 and that the magnetic separation process is effective for filteration of manetite fine particles.
