Using these diagrams, thermodynamic analysis is carried out to show the effect of technical conditions on soda decomposition of scheelite. It appears that the concentration of has direct effect on soda decomposition of scheelite. When the alkalinity is low, will hydrolyze to , accordingly the decomposition rate of scheelite becomes lower because of the decrease of . So in order to get higher leaching rate in industry practice, it is necessary to use enough amount of soda to serve as digestion reagent and, certain amount of NaOH to maintain high enough alkalinity.

利用这些热力学平衡图对Na2CO3分解白钨矿的工艺条件进行了分析，认为溶液中浓度直接影响白钨矿分解，而当碱度较低时，Na2CO3将水解生成，从而降低浓度，进而降低白钨矿的分解率；故在工业实践中，为使钨最大限度地转入溶液，除了保证足够的Na2CO3用量，还必需添加NaOH以维持一定碱度。

With development of economy in our country, demand for resources in especial for altogether coal have increasingly augmented according to the booming market.
