摘要/Abstract

摘要： 对钒渣添加石灰石氧化焙烧过程进行了研究，分析工艺参数变化对钒浸出效果的影响及其与物相转化行为的关系。结果表明，在本文实验条件下，焙烧熟料微观形貌一般呈多物相聚合形态，包括细条或粒状固溶体R2O3、熔化或半熔化态的偏钒酸钙(Ca, Mg) (VO3)2和焦钒酸钙(Ca, Mg)2V2O7、条状铁板钛矿Fe2TiO5以及辉石相。随焙烧温度和钙钒比m(CaO)/m(V2O5)的提高、以及焙烧加热速度的降低，钒转浸率随之增加。但温度和钙钒比过高、加热速度过慢均使硅钙反应加强，形成Al1.77Ca0.88 Si2.23O8或Ca2SiO4，不利钒的转化和浸出。适宜的焙烧条件为焙烧温度900℃左右、焙烧加热速度2-2.66℃/min和钙钒比0.6。

Abstract: The process of oxidation roasting of vanadium slag with participation of limestone was studied. The effects of process parameter variation on leaching of vanadium slag and the relationship between those and the behavior of phase transformations were analyzed. The results show that the micro morphology of the roasted clinker generally presents the aggregation of the multiple phases under the experimental conditions in this paper, including thin or granular solid solution R2O3, molten or semi molten calcium metavanadate (Ca, Mg) (VO3)2 and calcium pyrovanadate (Ca, Mg)2V2O7, stripy pseudobrookite Fe2TiO5 and augite. The vanadium leaching ratio is increased with raising the roasting temperature and the CaO/V2O5 ratio and decreasing the heating rate. However, excessively high roasting temperature and CaO/V2O5 ratio, and excessively low heating rate enhance the reaction of silica and calcia to form Al1.77Ca0.88Si2.23O8 or Ca2SiO4, which are not favorable to the transformations and the leaching of vanadium. Appropriate roasting conditions are the roasting temperature at about 900℃, heating rate at 2-2.66℃/min and CaO/V2O5 ratio of 0.6.

Key words: vanadium slag, limestone, oxidation roasting, phase transformations, calcium vanadates, leaching ratio
