| 摘 要： | 硫酸钾是一种有着广泛应用的工业原料和农业肥料,其生产技术主要是通过海水或卤水中的硫酸盐与氯化钾反应制得。我国盐湖资源和盐类储量极其丰富,这为硫酸钾的制备生产提供了更多途径。但对于不同水化学类型的盐湖,需采取不同的提钾制备硫酸钾工艺路线。在以往盐湖钾盐提取和硫酸钾生产技术研究的基础上,针对碳酸盐型盐湖扎布耶盐湖中钾盐和硫酸钾的提取和制备方案进行了论述及设计,并指出了蒸发结晶法、化学沉淀法和吸附及离子交换法等几种方法在技术上都有其可行性。但在工业生产中可以考虑将这几种方法有机结合,以达到钾的最大富集,降低硫酸钾生产成本,并有利于保护环境。

| Abstract: | :Potassium sulfate is a kind of widely used industrial raw materials and agricultural fertilizer,it is mainly prepared by reaction of seawater or brine potassium sulfate and potassium chloride.Lake resources and salt reserve in China are very rich, which provide more routes for the production of potassium sulfate. But for different type of water chemistry of the Saline Lake, different technique routes should be considered and used for the extraction of potassium and preparation of potassium sulfate. At present, extraction routes of potassium of the chloride-type of Saline Lake as Qarhan Lake become more mature,while that of carbonate-type such as Zabuye Saline Lake is just the beginning.In this paper, methods of extraction of potassium and preparation of potassium sulfate for the aim of development of carbonate-type Saline Lake were discussed based on the technologies of some saline lake, and the feasibility and problems of several methods have also been pointed out. |
