系统地研究了钨矿物原料碱解过程的一系列基础理论问题,包括黑钨矿及白钨矿与NaOH反应的动力学,Na_2WO_4-NaOH。H_2O系的物理学性质及浸出过程中某些杂质的行为。研究表明,黑钨矿及白钨矿与NaOH的反应属二级反应。在NaOH浓度为200～400g/l,温度为90～105℃范围内其表 A series of fundamental theoretical problems of alkali mineralization process of tungsten minerals have been systematically studied, including kinetics of reaction between wolframite and scheelite with NaOH, Na 2 WO 4-NaOH. Physical properties of H_2O system and the behavior of some impurities in the leaching process. The research shows that the reaction of wolframite and scheelite with NaOH belongs to the second order reaction. In the NaOH concentration of 200 ~ 400g / l, the temperature range of 90 ~ 105 ℃ its table
