| 英文摘要 | Sodium and calcium salts roasting are main processes for the production of vanadium compounds using vanadium slag as raw material. These processes suffer from heavy pollution and operation difficulty, respectively. Based on the principle regarding ferrovanadium spinel oxidation, as well as investigation of vanadium phases鈥?in situ transformation, a clean and efficient vanadium extraction process featuring non-salt vanadium slag roasting, ammonium meta-vanadate conversion, was established. The new process is expected to be able to realize high vanadium recovery and reduce exhaust gas and wastewater at source. Further, the tailing can be comprehensively utilized in conjunction with ironmaking process. This process may provide scientific and technical support for the green upgrading of vanadium industry. 漏 The Minerals, Metals & Materials Society 2020. |
