含碱金属的钽富集物分解方法研究

Study of Decomposition of Enriched Ta-bearing Alkaline Metals

分析了碱金属K、Na对钽富集物分解率的影响情况 ,应用沉淀的转化理论 ,用石英粉作转化剂 ,适量加入 ,全过程不加热 ,分解率从 92 %提高至

Analysis is made of the influence of alkali metals K and Na on the decomposition ratio of enriched Ta.The decomposition ratio can be improved from 92% to ≥99% by the adoption of precipitation conversion theory and proper addition of quartz powder as conversion agent without heating throughout the process.
