The spherical structure of titanium-bearing iron sand transformed to polyhedral structure gradually in the ball-milling process. With a ball-milling duration of 1.0 h, the mass percentage of the titanium-bearing iron sand with a particle size less than 75 μm is up to 63%, and the specific surface area reaches 439.6 m 2 ·kg −1.
