含氢氟酸和盐酸的混合酸的回收利用方法

简要综述了含氢氟酸和盐酸的混合酸回收利用方法。分别介绍了用含氢氟酸和盐酸的混合酸生产氟化钙、氟化镁、氟化锂、氟化氢钠和氟硅酸钾,同时产生盐酸或氯化物的方法。得到的产品质量好、成本低,对氟资源的综合利用和环境保护具有积极意义。

Technologies of Recycling the Mixture Composed of Hydrofluoric acid and Hydrochloric acid

In order to dispose the fluoride-bearing industry byproduct and to recycle the mixture composed of hydroflu-oric acid and hydrochloric acid,the paper reviewed methods for recycling the mixture.It introduced the produce technolo-gies of calcium fluoride,lithium fluoride,sodium hydrogen fluoride and potassium fluosilicate respectively,with the mixture composed of hydrofluoric acid and hydrochloric acid,and at the same time hydrochloric acid or chloride was pro-duced.These products are possessed of good quality,lower production cost.And the item is active significance for com-prehensive utilization of fluoride resources and for environment protection.
