本文从钨水溶液化学的特点出发,讨论了碱性介质和弱酸性介质中钨离子交换的特点。对目前最常用的几种阴离子交换树脂的吸钨特性分别作了分析。并列举实例说明了各种不同情况下离子交换树脂在钨湿法冶金中的应用。还简介了分离钨、钼的树脂,净化仲钨酸铵母液用的树脂以及制备水溶性很大的偏钨酸铵所用的树脂。
Based on the chemical characteristics of tungsten aqueous solution, this paper discusses the characteristics of tungsten ion exchange in alkaline medium and weak acid medium. Tungsten characteristics of the most commonly used anion exchange resins were analyzed separately. An example is given to illustrate the application of ion exchange resins in tungsten hydrometallurgy under various conditions. Also describes the separation of tungsten, molybdenum resin, purified ammonium paratungstate mother liquor resin and the preparation of water-soluble ammonium metatungstate resin.
