| 摘 要： | 研究目的在于探讨用罗布泊罗北凹地卤水制取硫酸钾混盐的一种新方法。设计要求在冬季生产备用卤水，至春、夏季与原卤水混合，用以改变罗北凹地生产卤水的成分，而不需要加入钾矿物就可以把卤水成分点在五元体相图中的位置调整到最佳蒸发点，后经蒸发及兑卤等流程生产出高质量的钾混盐，即可获得含杂质较低硫酸钾镁盐。采用罗北凹地冬季冻卤水与春、夏季卤水混合生产钾混盐，方案是可行的，生产成本亦较低。

| Abstract: | This paper probes into a new method for making potash-bearing salts mixtures through the processing of magnesium sulfate sub-type brine of Luobei depression in Lop Nur Lake. This processing procedure is as follows: in winter, reserve frozen brine is prepared in advance; during spring and summer, the frozen brine is mixed with original brine, thus changing and adjusting the composition of brine for production of potash, in which no additional potassium minerals are added. As a result, the brine composition in the five-member system metastable phase map is adjusted to the best position; through evaporation, the higher-quality potash-bearing salts mixtures, i.e., potassium and magnesium sulfates with lower content of impurity, can be produced from the brine. The mixing of frozen brine with original brine for making potash-bearing salts is based on a new idea, whose design is feasible and whose operating cost is relatively low. |
