Abstract

A sample of the natural brine of the Volgogradskoe bischofite deposit is subjected to chemical analysis to determine the concentrations of macro- and microcomponents: magnesium, chlorine, potassium, lithium, bromine, and boron. The process of precipitation of magnesium carbonate MgCO₃⋅3H₂O is developed and tested on the natural brine, and the behavior of the microcomponents (potassium, lithium, boron, and bromine) during precipitation is studied. The data obtained allow us to recommend a possible sequence of stages of extraction of components from bischofite brine during its processing. The conditions for obtaining magnesium oxide from magnesium carbonate are found.

从 Volgogradskoe 水氯镁石矿床的盐水中生产碳酸镁和氧化镁

摘要

对伏尔加格勒水氯镁石矿床的天然盐水样本进行化学分析，以确定常量和微量成分的浓度：镁、氯、钾、锂、溴和硼。_{开发了碳酸镁MgCO 3} ⋅3H ₂ O的沉淀过程并在天然盐水上进行了测试，并研究了沉淀过程中微量成分（钾、锂、硼和溴）的行为。获得的数据使我们能够推荐在水氯镁石盐水加工过程中提取成分的可能的阶段顺序。找到了由碳酸镁制取氧化镁的条件。
