What are the Advantages and Disadvantages of Magnetic …
While magnetic separators offer substantial advantages, some downsides need consideration too: 1. Limited Applications. Magnetic separation performs poorly with non-magnetic or only weakly magnetic materials like gold and graphite. Using it as the sole method won't effectively process these ores.

The produced NiFe 2 O 4 acted well in response to the magnetic field, and its purity was further increased to 95–96% through a two-stage process consisting of grinding and magnetic separation. The nano-sized spherical NiFe 2 O 4 with saturation magnetization of 34.66 and 30.82 emu. g −1 was obtained from H 2 SO 4 and HCl residues, respectively.

Efficient flotation separation of picromerite and halite by a …
Moreover, the corresponding flotation rate constant (k) of picromerite (1.34953) was much higher than halite (0.54951), which indicated that the flotation rate of picromerite and halite varied when SDBS was used as a collector. These results confirm that SDBS can achieve an excellent separation result of picromerite and halite.
