We conducted a two-dimensional numerical simulation of ferromagnetic floe motion (coagulated particles containing ferromagnetic particles) in a magnetic field and a flow field to analyze the effect of number and filling rate of magnets on magnetic separation performance. In the present study, we used magnetic fields applied by permanent neodymium magnets. The calculation results show that the magnetic separation performance is more greatly influenced by the number than the dimensionless interval of permanent magnets. The results also show that the logarithm of the residual rate of ferromagnetic floes is approximately proportional to the number of applied magnets. Commercial soft wares, Star-CD and ELF-MAGIC, are used for numerical analysis on fluid and magnetic filed in this study.
