The magnetic properties of the ore can be expressed by the specific magnetic coefficient X 0 . The specific magnetization coefficient X 0 represents the amount of force per unit volume of material in a standard magnetic field. For example, ferromagnetic iron ore minerals its specific magnetic susceptibility X 0 = 80000 × l0 - 6 cm / g; and weak magnetic hematite X 0 = 290 × 10 than the susceptibility - 6 cm / g. The magnetic strength is different, and the specific magnetization coefficient is very different.
