Beneficiation of Vanadium and Titanium Oxides by Using Selective Extraction of Iron in Low-Titanium Magnetite Concentrate

Abstract

Issues with existing vanadium beneficiation stimulate the development of new technologies for wasteless production of vanadium. The present work investigates a possibility of beneficiation of vanadium and titanium oxides in a low-titanium magnetite concentrate by using selective reduction and extraction of iron. Iron was selectively reduced by coal without melting and separated from the oxide (slag) phase during further smelting operation. After the liquid-phase separation vanadium and titanium oxides were accumulated in a slag phase. The following products were produced: slag, containing vanadium and titanium oxides, and iron with relatively low carbon content. The content of vanadium and titanium in a final product has increased in comparison to the initial concentrate.

Solid-Phase Reduction of Iron from Suroyam Titanomagnetite Ore during Metallization in Rotary Kiln

“…Thereby, the ore of the Suroyam deposit is unsuitable for the extraction of iron and vanadium using the existing processing scheme. However, it remains a raw material for the future possibility of iron and vanadium production ore when using new theories and technologies for their processing [4][5][6][7][8][9][10].…”

Thermodynamic Modelling of the Metals’ Reduction Process From the Suroyam Titanomagnetite Concentrate

“…Прогнозные ресурсы месторождения по категории Р1 превышают 2,2 млрд т титаномагнетитовых руд, а до глу-бины 300 метров -6 млрд т. Основным эле-ментом является железо, содержание которого составляет 16,5 %, попутно можно извлекать также титан, ванадий и фосфор [1][2][3][4][5][6][7]. Титано-магнетитовые руды с содержанием: железа -14,3 %, железа магнетитового 9,5 %, диоксида титана -1,03 %, пентаоксида ванадия -0,09 %, пентаоксида фосфора -0,33 %.…”
