To achieve high efficiency utilization of Panzhihua vanadium titano-magnetite, a new process of metalizing reduction and magnetic separation based on hot briquetting is proposed, and factors that affect the cold strength of the hot-briquetting products and the efficiency of reduction and magnetic separation are successively …

2.1. Materials. In this experiment, vanadium-titanium magnetite concentrate from Wuling, Xinjiang was used as raw material, and its chemical composition is depicted in Table 1.It can be observed from Table 1 that the main valuable elements in the raw iron concentrate are Fe, V and Ti, with the mass fractions of TFe, TiO 2 and V 2 O 5 are high …

In this study, there is 1.42% P2O5 in the P-containing V-Ti magnetite tailings in Miyi Region of China, with the valuable minerals mainly including apatite, and aluminosilicate minerals as the main gangue components. The direction flotation process was used to recover phosphorous from the low-grade phosphorous-bearing V-Ti …

To improve the recovery rate of valuable metals in V-bearing titanomagnetite, Chen [7] studied the comprehensive extraction of Fe/V/Ti by selective reduction to obtain a high-grade (TFe = 80.83% ...

Abstract. Titano-magnetite is an ore of iron and titanium, and is highly magnetic. Magnetite and ilmenite are two major minerals. Ilmenite exhibits various textural dispositions.
