Winning iron and titanium while making vanadium electrolyte

By Paul Grad |

VanadiumCorp Resource Inc. (Vancouver, B.C., Canada; www.vanadiumcorp.com) has achieved direct and consistent recovery of vanadium electrolyte, vanadium oxides and titanium from vanadiferous titanomagnetite (VTM; vanadium-rich Fe3–xTixO4) using hydroelectricity, from the company’s Lac Dore Vanadium Project in Quebec. The company has partnered with Electrochem Technologies & Materials (Montreal, Que., Canada; www.electrochem-technologies.com) for the development of technologies to obtain high-performance vanadium electrolyte for energy storage applications. VanadiumCorp has also successfully recovered high-purity electrolytic iron directly from VTM concentrate from drill core from its La Dore Vanadium Project using conventional milling and magnetic separation. The company’s president and CEO, Adriaan Bakker, says the technology was developed keeping in mind that in addition to vanadium, both iron and titanium also have high value. Currently available technology was not able to recover all three metals while producing high-purity iron. Conventional pyrometallurgical processes use either direct soda-ash roasting of the magnetite followed by water leaching, or arc smelting and slagging of the magnetite followed by soda ash…
