Based on the magnetic difference between fayalite and magnetite, magnetic separation is usually used to separate them [4]. However, because the particle size of fayalite is smaller than that of magnetite, mechanical inclusions are very easy to exist in the process of magnetic separation, which leads to the entry of fine fayalite into concentrate [5], [6].
