Mechanism and kinetics study of vanadium leaching from landfilled metallurgical residues by ultrasonic with ozonation enhancement in a low-acid medium

Ultrasonics Sonochemistry, Год журнала: 2024, Номер 109, С. 106998 - 106998

Опубликована: Июль 17, 2024

Landfilled metallurgical residues are valuable raw materials for the recovery of strategic vanadium resources. However, efficient separation from these is challenging due to its strong oxidation resistance and coating within silicate inclusions. To address this issue, study proposes an enhanced leaching process utilizing synergistic effect O

Effect of Major Impurity in the Vanadium‐Rich Solution on the Growth of NaV₂O₅ Crystals under Hydrothermal Conditions

Advanced Engineering Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 10, 2025

NaV 2 O 5 is a promising cathode material for ion batteries with high capacity and good cycle performance. The concentration of vanadium low impurity in vanadium‐rich solution makes it possible to be used as raw product preparation. Vanadium containing was prepared investigate its influence mechanism on crystal precipitation. four major elements the precipitation following order P > Al Si Fe. With increase concentrations, conversion rate V content precipitates decreased varying degrees, while increased. When concentrations Fe, were high, resulting precipitate still , but structure changed. AlOH SiOH hider condensation between VOH broke rod into irregular flakes blocks. As gradually increased, changed from VO (H O) 0.5 then Na 3 .053((V 9 )(PO 4 )2(OH)0.1(H O)8, meanwhile, morphologies plate, cross‐like, finally cube. Revealing growth conducive popularization process.
