利用西台吉乃尔盐湖卤水在小盐田进行制取软钾镁矾的工艺研究

Study on the Process of Preparing Picromerite in Small Yantian by West taijnar Saline Lake brine

以西台吉乃尔盐湖卤水为原料,通过日晒蒸发在盐田直接生产高质量的软钾镁矾的工艺是否可行,探讨盐田各物相控制点的工艺参数,采用多段结晶条件下,在软钾镁矾区段中常温下进行固液分离,一次转化收率在35%~45%之间,循环收率接近于80%。

The West taijnar Saline Lake bittern as raw material, soft leonite direct production of high quality in Yantian by solar evaporation is the process of potassium sulfate magnesium fertilizer is feasible, process parameters and to explore the Yantian each phase control points, improve the recovery of potassium magnesium fertilizer quality and rate of K A, provide technical parameters for large Saltpan in producing high quality soft potassium magnesium sulfate.
