Abstract

Abstract

Due to the heterogeneous coagulation of fine-grained gangue minerals and titanomagnetite in the mixed rough concentrate of a fine-grained titanomagnetite in Panxi area, the iron extraction and impurity reduction index of conventional low-intensity magnetic separation is poor. The enhanced dispersion-magnetic separation can effectively improve the separation effect and improve the separation index. In order to strengthen the separation of fine-grained iron minerals in the ore samples, the experimental study on the process conditions of enhanced dispersion-magnetic separation was carried out to investigate the effects of dispersant type, dispersant dosage, slurry pH, magnetic field strength and other factors on the separation effect. The test results show that under the conditions of 20% slurry concentration, mechanical stirring speed of 1 992 r/min, stirring time of 3 min, dosage of SHMP of 1 000 g/t, slurry pH of 10 and magnetic field strength of 300 kA/m, a good index of 57.69% iron grade in concentrate and 98.10% iron recovery was obtained. Compared with the results of direct magnetic separation, the iron grade increased by 1.26%. DLVO theoretical analysis shows that sodium hexametaphosphate increases the electrostatic repulsion between titanomagnetite and titanaugite by reducing the surface potential of titanomagnetite and titanaugite, thus weakening the heterogeneous coagulation of fine gangue minerals and titanomagnetite.
