| 摘 要： | 国内很多锂业回收锂后的废液中含有大量的铝、氟离子,由于回收成本过高或其它原因而直接排放,造成资源浪费和环境污染.锂厂废液与氨水反应得含铝、氟的复合物沉淀和含氨溶液,试验研究了各参数对铝、氟回收率的影响,得到优化的工艺条件,铝回收率93%,氟回收率92%.将得到的铝、氟复合物与氢氟酸、纯碱反应制备冰晶石,试验研究各参数对合成冰晶石的质量和得率的影响,优化条件下,冰晶石得率96.44%,产品符合冰晶石国家和行业标准.废液处理过程中,没有新的污染物产生,过程经济效益好.

| Abstract: | The exhaust liquor from the domestic lithium manufacture plant recycling lithium containing a large number of aluminum and fluorine ion,was directed bleed-off,because of high cost recovery or other reasons,it will lead to environment pollution and a waste of resource.The reaction taking place between the waste and ammonia gained the complex of aluminum and fluorine precipitation and ammoniated solution.Through the single factor experiment,the influence of each factor on the recovery of aluminum and fluorine... |
