钼酸铵溶液中两种除钨方法比较研究

摘要

Deep tungsten separation from ammonium Molybdate solution is a technical difficulty. An experimental research is conducted to study the problem of ammonium molybdate solution containing a big amount of Tungsten by adding different reagents, and two new methods of removing tungsten are used. The result of adding ferric Molybdate to separate Tungsten is 80%, much better than traditional method. The percent of WO3 is less than 0.1g/kg by separating W from Mo, which is the first class in GB.%针对从钼酸铵溶液中深度除钨这一技术难题,通过添加不同的试剂,对钼酸铵溶液中含钨高的问题进行了试验研究,提出了两种新的除钨方法,其中钼酸铁除钨率高达?80%,远大于传统方法,通过钨钼分离后的钼酸铵产品中WO3 含量低于?0.1?g/kg,达到国标一级钼酸铵.
