摘要
根据我国盐湖的自然气候条件和资源特点,以Na、K、Mg/Cl、SO_4-H_2O五元体系25℃介稳相图为依据,提出了一条经调节卤水组成后,藉盐田天然日晒蒸发获得软钾镁矾的新工艺途径。文中给出了在窒内于模拟野外条件下进行实验的结果。过程中钾的回收率可达80%以上。
The Schoenite was obtained in laboratory using the technique based on the metastablephase diagram of the system Na, K, Mg/Cl, SO_4-H_2O at 25℃ and natural conditionsof salt lakes in Qinghai province, China. The process involves the regulation of the brinecomposition with mirabilite and carnallite and natural evaporation of the brine.
