除掉高浓度钼酸铵溶液中钒的研究

Remove high concentrations of vanadium in ammonium molybdate solution

钒是生产钼酸铵过程中的一种杂质,钒含量过高会导致生产的钼酸铵晶体颜色发黄,直接影响钼酸铵的纯度和它的使用价值。在钼酸铵溶液中,钒主要以钒酸铵的形式成在,它能与强碱性阴离子树脂发生离子交换,此类型树脂是钒工业生产钒的主要工具,也是其他冶金过程中用来除掉钒作为杂质的工具。在钼冶金过程中,如果能够把钒提出来,即提高了钒的使用价值,也能够对资源充分利用。本实验用镍钼矿为贵州毕节纳雍水东地区矿作为原料。钒含量约为0.05%。

Vanadium is a process of production of ammonium molybdate impurity, high vanadium content leads to production of ammonium molybdate crystal color yellow, a direct impact on the purity of ammonium and his value. In the ammonium molybdate solution, mainly vanadium into vanadium in the form of ammonium, which can occur with the strong base anion ion exchange resin, the resin of this type of vanadium is the main tool of industrial production of vanadium is used to remove other metallurgical process vanadium as impurities tool. In the molybdenum metallurgical process, if we can make to vanadium, the use of machines to improve the value of vanadium, vanadium is also able to use from the points. In this study, nickel molybdenum is SuiDong NaYong BiJie as a raw material. Vanadium content of about 0.05%
