摘要/Abstract

摘要： 以硼精矿为原料、Na₂CO₃为钠化剂，在TG-DTA热分析基础上，研究了硼精矿钠化焙烧-水浸制取硼砂过程中Na₂CO₃用量、焙烧温度、焙烧时间、成型压力对B₂O₃浸出率的影响，采用X射线衍射和扫描电镜对硼精矿钠化焙烧产物和硼砂制品的相组成和显微形貌进行了表征分析。结果表明：在5倍Na₂CO₃理论用量、样品成型压力5 MPa、温度850℃、保温3 h最优条件下，硼精矿中主要含硼矿物硼镁石[MgBO₂（OH）]转变为可溶性硼酸钠盐Na₃BO₃和Na₂B₄O₇，实现了硼矿物活化和碱解过程同步完成。焙烧产物经常压水浸，B₂O₃浸出率达91.05%。水浸滤液经除杂、蒸发、浓缩后获得了结晶良好的硼砂制品。

Abstract: Based on TG-DTA analysis, a sodium-roasting and water-leaching process were employed for the preparation of borax from boron concentrate, using Na₂CO₃ as sodium treatment reagent. The effects of Na₂CO₃ content, roasting temperature and holding time on leaching rate of B₂O₃ were investigated. Phase compositions and morphologies of roasted products and borax were analyzed by XRD and SEM. The results indicate that the optimal processing parameters are fivefold theoretical amount of Na₂CO₃, molding pressure of 5 MPa, roasting temperature of 850℃and holding time of 3 h. Under these conditions, activation and alkaline hydrolysis of boron mineral are completed synchronously, which make transformation of MgBO₂(OH) into soluble Na₃BO₃and Na₂B₄O₇. The leaching rate of B₂O₃ in roasted products reaches 91.05%. Well-crystallized borax is obtained from leached filtrate after treatments of removing impurity, evaporation and concentration.
