Metallurgical testing on the vanadium pipe samples from Tando Resources’ SPD project in South Africa has yielded a concentrate assaying 2.03% vanadium and 13.3% titanium.
Initial metallurgical test work on Tando Resources’ (ASX: TNO) SPD vanadium pipes has confirmed the magnetic pipes could pose “significant upside” for the South African project.
Test work was undertaken on high-grade samples and wet low intensity magnetic separation yielded a concentrate assaying 2.03% vanadium and 13.3% titanium with minimal waste elements.
According to Tando, the results indicate SPD vanadium pipe mineralisation is “highly amenable” to the simple processing method, which means the mineralisation could be sold as a direct shipping ore to end-users without further treatment.
The next stage of test work will investigate the concentrate’s responsiveness to leaching via two different methods to achieve a battery grade product.
Under the first treatment, Tando will evaluate salt roasting the material then expose it to acid leaching, while the second method will look at direct leaching from the concentrate.
Established vanadium producers such as Largo Resources (TSX: LGO), Bushveld Minerals (LSE: BMN) and Glencore (LSE: GLEN) use the established roasting and acid leaching method.
