Separation of molybdenum in production process of ammonium paratungstate

钨钼分离是仲钨酸铵生产过程的重要工序,也是一大技术难题。通过对仲钨酸铵各种生产工艺的一般流程和钼的基本性质进行综述,较系统地分析了仲钨酸铵各种生产工艺中钨钼分离方法的优点与不足。分析表明:离子交换法除钼具有工艺流程短、钨的损失小、除钼效果好、操作简单、环境污染小、经济可行等优点,因而具有较好的工业应用前景。

Separation of tungsten and molybdenum in production process of ammonium paratungstate is an important working procedure,but this is always one of difficult technical problems. General flows of various ammonium paratungstate technologies and the basic nature of molybdenum were summarized. Moreover, advantages and disadvantages of each separation method for tungsten and molybdenum in production process of ammonium paratungstate were systematically analyzed. Analysis results indicated that there are many advantages, such as short process flow,small tungsten loss,good molybdenum eliminating effect, simplicity of operation, low environmental pollution, and economy feasibility to eliminate molybdenum by using ion exchange method. It is precisely because of these advantages, ion-exchange method to eliminate molybdenum has a very good industrial application prospect.
