Bushveld Minerals has unveiled the latest results from pyrometallurgical testwork at its Bushveld vanadium and P-Q deposits in Limpopo Province.
The company is conducting a pyrometallurgical testwork programme for the beneficiation of the Main Magnetite MML layer, as part of the scoping study for the Bushveld vanadium project.
The testwork will evaluate two alternative proven processing routes:
- the salt roast process to produce vanadium pentoxide flakes and/or ferrovanadium, and
- the smelting process to produce pig iron or steel and high-grade vanadium slag.
The company recently completed modelling of the smelting beneficiation route. This flowsheet entails pre-reduction in rotary kilns, smelting in electric arc furnaces and vanadium extraction from the hot metal through a shaking ladle circuit. Testwork continues on the salt roast beneficiation route.
The modelling exercise, conducted on Bushveld vanadium project’s MML resource by Hatch Goba and Exxaro Research and Development, has yielded positive results, confirms Bushveld Minerals.
