Abstract: The process of the invention is an improvement over the existing process of producing salt of high purity from alum-treated brine disclosed recently in the prior art. More particularly, the invention rectifies the ratio of Ca2+ to Mg2+ from a value
Abstract translation: 本发明的方法是相对于现有技术中最近公开的由明矾处理的卤水生产高纯度盐的现有方法的改进。 更具体地说，本发明将Ca2 +与Mg2 +的比值从值<1改为由氯碱和苏打灰工业所要求的2-3的范围内的值。 改进的方法包括用HCl水溶液调节澄清盐水的pH，以便在pH6.5下进行盐结晶，而不是在7的天然pH下进行盐结晶。pH调节降低了盐中的Mg 2+杂质，同时略微提高了Ca2 +杂质 在盐中，从而达到所需的比例。
