摘要
冰晶石(Na3AlF6)是炼铝工业中不可缺少的助溶剂,在其他行业也有较广的用途。简要介绍了不同的合成工艺,分析了各种工艺的优、缺点。在此基本上,研究了合成工艺应用于氟碳铈型稀土矿伴生氟资源的利用领域,为稀土清洁生产及氟的资源化提供了应用途径,给出了初步的研究结果。
Cryolite （Na3AlF6） was the indispensable cosolvent of the aluminum industry, and had a broader purpose in other industries. The different cryolite synthetic technologies were introduced briefly and the advantages and disadvantages of the various processes were analyzed. The synthetic process used in the field of bastnaesite rare-earth that associated fluorine-type mineral resources was studied. It provided a green way for RE cleaner production and resource utilization of fluoride. Finally, the results of a preliminary study were presented.
