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。

This makes more and more people pay more attention to studies and applications of numerical simulation in thermal recovery. In this research, we have developed a reliable mathematical model for thermal recovery, which takes a full consideration of the effect of viscos, gravitical and capillary forces on the three-phase flow of gas, water and oil, the effect of the temperature on the medium characteristics of liquid and solid, the phase equilibrium of gas-liquid in each component, heat transportation including connection, conduction and radiation as well as heat losses in both the overburn and underlying strata. In the space discreation of the mathematical model, we have proposed a new method based on the improvement of the conventional nine-points difference approximation, which has a higher difference accurancy.
