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。 Ammonium paratungstate (APT) was produced by ion exchange method according to the characteristics of surrounding tungsten resources in Gejiu, Yunnan Province. The process adaptability of 201 × 7 resin was explored in terms of liquid alkali concentration, adsorption rate, temperature and impurity extraction rate. Through the applicability study, when NaOH is 12 g / L, the flow rate of the solution is 10 m3 / h and the temperature is controlled at 50 ℃, the optimal parameters are obtained. The controllable 201 × 7 resin can be used to control the impurity elements entering into the process, Increase the exchange column about 10% of capacity.
