Mount Ridley Mines' patent-pending Selectro process recovered 96% vanadium, 49% titanium and 78% iron from a third-party titanomagnetite sample, its third distinct feed type. The company claims titanium and iron co-products could subsidise and de-risk primary vanadium production outside China for VRFB electrolyte supply.
Largo Inc. reported Q3 2026 vanadium production of 2,093 tonnes V2O5, down from 2,636 tonnes a year earlier, as it deliberately cut output to reduce inventories and focus on high-margin products. Sales were essentially flat at 2,428 tonnes and nine-month output rose 23% year on year to 7,609 tonnes.
Largo produced 2,093 t of V2O5 in Q3 2026, down from 2,636 t a year earlier, while sales stayed essentially flat at 2,428 t and copper, gold and PGM by-products came online.
