During the process of extracting vanadium from vanadium slag by sodium roasting-water leaching method, silicon in the leaching solution will react with alkali to form sodium silicate and enter the solution, affecting the recovery rate and quality of the product. To address this issue, the selective precipitation of silicon in vanadium leachate by the magnesium salt method was studied. Thermodynamic equilibrium diagrams of the Mg-Si-V-H2O system were constructed to investigate the distribution characteristics of free ions within the pH range of 7~14. Additionally, the relationship between pH and precipitation saturation indices was established to evaluate the precipitation behaviors of MgSiO3 and Mg(VO3)2 under different pH conditions. The calculation results reveal that the solubility of MgSiO3 is relatively low, while that of Mg(VO3)2 is relatively high, which can achieve the selective precipitation of silicon in the vanadium leaching solution. The verification test results demonstrate that the pH of the solution has a significant influence on the precipitation rate of silicon in the vanadium leaching solution. When pH=10, the silicon precipitation rate can reache 86.3%, and the vanadium loss rate is only 3.2%, with a good effect.

采用钠化焙烧—水浸工艺从钒渣中提钒时,浸出液中的硅会与碱反应形成硅酸钠并进入溶液,影响产品回收率和质量。针对这一问题,研究了采用镁盐法选择性沉淀钒浸出液中的硅,通过绘制Mg-Si-V-H2O体系的热力学平衡图,分析了pH在7~14范围内,体系中各游离离子的分布特性。同时,建立了pH与沉淀饱和指数的关系曲线,探讨了MgSiO3和Mg(VO3)2在不同pH条件下的沉淀行为。计算结果表明,MgSiO3溶解度较低,而Mg(VO3)2溶解度相对较高,可实现钒浸出液中硅的选择性沉淀。验证试验结果表明,溶液pH对钒浸出液中硅的沉淀率有较大影响,当pH=10时,硅沉淀率达86.3%,钒损失率仅为3.2%,效果较好。

采用钠化焙烧—水浸工艺从钒渣中提钒时,浸出液中的硅会与碱反应形成硅酸钠并进入溶液,影响产品回收率和质量。针对这一问题,研究了采用镁盐法选择性沉淀钒浸出液中的硅,通过绘制Mg-Si-V-H2O体系的热力学平衡图,分析了pH在7~14范围内,体系中各游离离子的分布特性。同时,建立了pH与沉淀饱和指数的关系曲线,探讨了MgSiO3和Mg(VO3)2在不同pH条件下的沉淀行为。计算结果表明,MgSiO3溶解度较低,而Mg(VO3)2溶解度相对较高,可实现钒浸出液中硅的选择性沉淀。验证试验结果表明,溶液pH对钒浸出液中硅的沉淀率有较大影响,当pH=10时,硅沉淀率达86.3%,钒损失率仅为3.2%,效果较好。

During the process of extracting vanadium from vanadium slag by sodium roasting-water leaching method, silicon in the leaching solution will react with alkali to form sodium silicate and enter the solution, affecting the recovery rate and quality of the product. To address this issue, the selective precipitation of silicon in vanadium leachate by the magnesium salt method was studied. Thermodynamic equilibrium diagrams of the Mg-Si-V-H2O system were constructed to investigate the distribution characteristics of free ions within the pH range of 7~14. Additionally, the relationship between pH and precipitation saturation indices was established to evaluate the precipitation behaviors of MgSiO3 and Mg(VO3)2 under different pH conditions. The calculation results reveal that the solubility of MgSiO3 is relatively low, while that of Mg(VO3)2 is relatively high, which can achieve the selective precipitation of silicon in the vanadium leaching solution. The verification test results demonstrate that the pH of the solution has a significant influence on the precipitation rate of silicon in the vanadium leaching solution. When pH=10, the silicon precipitation rate can reache 86.3%, and the vanadium loss rate is only 3.2%, with a good effect.
