Abstract

Calcification roasting-acid leaching is a clean, efficient, and environmentally friendly process, but in the roasting process, the local temperature is often too high, the heat release is not timely, and the heat transfer is blocked. Furthermore, the material is easy to sinter, which affects the final vanadium extraction effect. In this paper, a small amount of CeO was introduced in the roasting process of vanadium slag to promote the calcified roasting. The results showed that the vanadium leaching rate reached 93.17% with the addition of 0.1 wt % CeO at a roasting temperature of 750 °C, which was higher than that obtained without CeO addition (90.00%). The results of XPS, XRD, and SEM-EDS analyses confirmed that adding CeO to the roasted clinker significantly increased the proportion of pentavalent vanadium to the total vanadium by up to 28.64%. O-TPD analysis revealed an enhanced chemisorbed oxygen with the CeO-assisted roasting, indicated the activation of oxygen by CeO, and resulted in an enhanced oxidation of vanadium. The work in this paper establishes an alternative route for catalytic oxidation-enhanced vanadium slag roasting, which can improve the utilization of vanadium slag at relatively lower temperatures under the action of CeO and is of positive significance in solving the problems of sintering and energy consumption in the roasting process.

摘要

钙化焙烧-酸浸是一种清洁、高效且环境友好的工艺，但在焙烧过程中，局部温度往往过高，热量释放不及时，传热受阻。此外，物料易烧结，影响最终的钒提取效果。本文在钒渣焙烧过程中引入少量CeO以促进钙化焙烧。结果表明，在750℃焙烧温度下添加0.1 wt% CeO时，钒浸出率达到93.17%，高于未添加CeO时的浸出率（90.00%）。XPS、XRD和SEM-EDS分析结果证实，向焙烧熟料中添加CeO显著提高了五价钒占总钒的比例，最高可达28.64%。O-TPD分析表明，CeO辅助焙烧增强了化学吸附氧，表明CeO对氧有活化作用，导致钒的氧化增强。本文的工作建立了一种催化氧化强化钒渣焙烧的替代路线，在CeO作用下可在相对较低温度下提高钒渣利用率，对解决焙烧过程中的烧结和能耗问题具有积极意义。
