The extraction of vanadium from titanomagnetites

2020-1-15 · Quenching after roasting (22.5–30% Na 2 CO 3, 1025 °C) resulted in increased chromium and vanadium extraction when leaching a Canadian titaniferous magnetite ore (Lucas and Ritcey, 1980). The optimum temperature for chromium extraction is higher than that for vanadium extraction ( Gabra and Malinsky, 1981 ), as might be expected based on the
