摘要/Abstract

摘要： 钒渣钠化焙烧过程低价钒氧化不充分，不能被浸出，降低了钒渣的浸出率。实验采用蒽醌磺酸钠（ADA）和栲胶作载氧体实现氧的传递，强化低价钒的氧化行为。通过X射线衍射、扫描电镜、紫外光谱以及紫外可见漫反射光谱等检测方法，分析了转炉钒渣浸出反应前后物相变化行为，探索了反应过程机理，证实了其可行性。结果表明，采用ADA和栲胶作载氧体，能将转炉钒渣中的低价钒氧化成可溶的高价钒，实现空气催化氧化高效浸钒。此时，钒浸出率由89.47%分别提高到92.84%和93.64%，且催化剂对体系后续工艺没有不良影响，转炉钒渣中的尾渣含钒量由1.1%分别降至0.52%和0.47%。

Abstract: Low valency vanadium produced in the insufficient sodium roasting process affects the improvement of vanadium leaching rate. Anthraquinone-2,6-disulfonic acid disodium salt (ADA) or tannin as oxygen carrier was added into the water leaching process to transfer oxygen and to strengthen the air oxidation process of low valency vanadium. Phases of reaction system were analyzed using XRD, SEM, UV and UV-Vis DRS. The reaction mechanism of the process was also studied to prove its theoretical feasibility. Low valency vanadium was effectively oxidized by ADA or tannin, and vanadium leaching ratios increased from initial 89.47% to 92.84% and 93.64%, while vanadium contents in the leaching residue reduced from 1.1% to 0.52% and 0.47%, respectively. It also proved that catalysts had no negative effect on the consequential process.
