The weak magnetic separation was applied to remove the residual titanomagnetite. The specific susceptibility of titanomagnetite was more than 38 × 10 −6 m 3 /kg, and the magnetic intensity was chosen within the range of 80–120 KA/m (Du et al., 2019, Wei, 2009). It was obvious that ilmenite-M was not captured into the weak magnetic concentrate.
