针对云南个旧周边钨矿资源的特点,采用离子交换法生产仲钨酸铵(APT),从交前液碱浓度、吸附速度、温度以及杂质脱出率等方面探索201 ×7树脂的工艺适用性.通过适用性研究,当NaOH为12 g/L、溶液流速为10 m3/h、温度控制在50℃时得到较佳参数,并提出控制201 ×7树脂不能分离的杂质元素进入流程,应用于生产中提高交换柱约10％的产能.%The ammonium paratungstate (APT) is produced by ion exchange method; the applicability of 201 × 7 resin in this process is discussed by the following aspects:caustic soda concentration of the liquid before exchange,adsorption velocity,temperature and impurities removal rate and so on according to the features of tungsten ore resources around Gejiu,Yunnan.The applicability study shows that the better parameters are NaOH concentration is 12 g/L,the solution flow velocity is 10 m3/h,the temperature is controlled under 50℃,and the impurity elements can't separate with 201 ×7 resin shall be controlled not to enter into the flow.This process applied to production increases the productivity of exchange column by 10％.
