摘要
通过对钾长石氟化学酸碱联合法提钾工艺进行热力学及经济性分析,阐释了该工艺路线能耗低、物耗低、成本低、产品结构合理等优势。该工艺不但实现了氟的循环利用,而且综合利用了钾长石中的铝资源,对于解决我国铝土矿资源缺乏的问题具有促进作用。
Thermodynamic and economic analysis of K-feldspar acid-alkali combined extraction with fluorine chemical process is made to explain the advantages of the technology being low energy consumption,low consumption of materials,low cost and reasonable structure of products.It has brought about recycling of fluorine and comprehensively utilized the aluminum resources in Kfeldspar as well.Moreover,it can help solve the problem of bauxite shortage China faces presently.
