Abstract

Abstract

The combined methods of dry-discarding and wet-discarding were used to separate the vanadium-titanium-magnetite waste rock in Panxi. The results indicated that the grades of TFe and TiO₂ which existed in the tailings reached 9.96% and 3.92%, respectively, and the recovery reached 23.73% using the dry-discarding method after the waste rocks were crushed to -40 mm. In addition, after the concentrates of dry-discarding were crushed to -5 mm, using the wet-discarding method, the grades of TFe and TiO₂ which existed in the tailings reached 7.86% and 2.81%, respectively, and the recovery reached 27.36%. Finally, the discarding rate reached 51.09% using the combination methods of dry-discarding and wet-discarding, and the TFe grade of concentrate increased 5.56 percentage, TiO₂ grade increased 2.75 percentage. The method could greatly reduce the subsequent grinding amount, improve the initial grade, and reduce the mineral processing cost.
