| 中文摘要: |
| 对某地钒矿石进行了成份分析、赋存状态的分析，证实了该矿石含20%以上的钒云母。为了提高该矿钒的浸出率，研究了盐酸浸取、硫酸浸取、未经焙烧样品的浸取、焙烧后样品的浸取、添加剂的用量对浸出的影响、焙烧温度及浸取时间等对浸出率的影响。建立了无盐焙烧、稀硫酸浸取，使浸出率达90%以上，为后续工业设计和生产提供了可靠的数据和依据。 |

| Vanadium ore for the component analysis，the analysis of the occurrence state，confirmed that the ore containing more than 20% of vanadium micaIn order to improve the leaching rate of vanadium，it was studied that hydrochloric acid leaching，sulfuric acid leaching，without calcination of samples soaking，roasting sample after leaching，the dosage of additives for leaching，roasting temperature and leaching time，the influence of the influence on the leaching rateNo salt roasting is established，dilute sulphuric acid leaching，the leaching rate above 90%，and for the follow-up industrial design and production provides the reliable data and basis. |
