中文摘要:

      湘澧盐矿区位于江陵凹陷南缘,该地区卤水中溴和钾的含量都达到了工业品位。对采集的湘澧盐矿卤水样品进行了化学全分析,并对分析的结果进行了研究,查明了卤水中钾和溴等元素的富集机理；提出关于卤水综合利用的工艺路线及可行性建议。等温蒸发实验表明,整个蒸发过程中均有石盐析出,失水量达到31.23%时,芒硝开始析出；此后,石盐和芒硝共同析出。整个蒸发过程中该卤水的析盐规律为,首先析出氯化钠,再析出硫酸钠,最后析出硫酸钾。

英文摘要:

      The xiangli salt mine locates in the south rim of jiangling sag, the area of brine and potassium in the area has reached the industrial grade. Xiang li salt brine samples for the chemical analyses, and the results of analysis are studied, find out the the elements such as potassium and bromine in bittern enrichment mechanism; The technical route and feasibility suggestions for the comprehensive utilization of brine were put forward. Isothermal evaporation experiments show that the evaporation process, has the stone salting out, loss of water reached 31.23%, the glauber’s salt precipitation, since then, rock salt and glauber’s salt precipitation. The analysis of the salt in the whole evaporation process is:the sodium chloride is precipitated firstly,then the sodium sulphate is precipitated and the potassium sulfate is precipitated at last.
