摘要
本文研究了用浓硫酸和氯化铵为原料制备高纯盐酸的新工艺,同时回收分离厂废水中的氯化铵,还可得到工业盐酸和可供稀土矿山应用的复合浸矿剂,这不仅减少了稀土分离厂的废水排放而且具有较大的经济效益。
A new technology used for preparing the hydrochloric acid with sulphuric acid and ammonium chloride was proposed,the ammonium chloride was partly taken from the waste water of rare earth seperation factory.However,it can produce the pure hydrochloric acid,industrial grade hydrochloric acid and the mingled extractant which is used in rare earth mine.It not only avoids the environment pollution but also takes a good economic benifit.
