| Abstract: | For vanadium titano-magnetite from Shaanxi Province, the process of low-intensity magnetic separation (LIMS) combined with acid leaching was adopted in the test for the enrichment and extraction of vanadium. It is found from the test that the raw ore was subjected to LIMS at the magnetic field strength of 50 kA/m for magnetic separation, resulting in the enrichment of magnetite with the grade of V2O5 increased from 0.24% to 1.09%. After that, the obtained concentrate was leached with sulfuric acid at concentration of 5 mol/L, reaction at the temperature of 100 ℃ for 60 min with liquid/solid ratio at 5∶1, leading to the vanadium leaching rate up to 80.45%. |
