近几年报导的文献指出,压煮矿浆经脱硅后再搅拌数小时是提高铝酸钠溶液硅量指数的方法之一。又指出,脱硅温度愈高,二次搅拌的效果愈明显。一部分研究人员研究了铝酸纳溶液加和不加灰泥、白泥及石灰压煮脱硅后,再搅拌矿浆4～6小时所产生的良好影响。铝酸钾溶液矿浆的再搅拌对其脱硅深度的 The literature reported in recent years pointed out that the pressure boiled pulp after desilication and then stirred for several hours is one of the methods to improve the silicon content index of sodium aluminate solution. Also pointed out that the higher the desiliconization temperature, the more effective the second agitation. Part of the researchers studied the good effect of adding sodium aluminate solution with and without mortar, white mud and lime boiled for desilication, and then stirring the slurry for 4 to 6 hours. The potassium aluminate solution slurry was desalinated for further depth of desilication
