青海盐湖资源开发与利用

青海西部盐湖有着丰富的钾、镁、锂、硼、锶等矿产资源,这些元素及其化合物在国民经济的发展中有着巨大的作用。本文阐述了盐卤水资源在制取锂盐、钠盐、水氯镁石、碳钠矾、硫酸钾、氧化钠、金属溴化物、硼砂等一系列化合物的途径。为防止生态环境的破坏,必须用科学的方法、先进的技术作指导,走综合开发的道路,为此进一步阐述了用水氯镁石生产金属镁的工艺流程,用胺法沉镁生产高纯镁砂与金属镁的联合流程。

EXPLOITATION AND UTILIZATION OF THE SALT-LAKE RESOURCES IN QINGHAI

There are rich salt lake mineral resources in the western of Qinghai,such as potassium,magnesium,lithium,boron,strontiumThese elements and their compounds have been playing a great role in progress of the national economyThis paper deals with the ways of which the bittern resources are used for preparation of a series of compounds such as lithium salt,sodium salt,hydrous magnesium chloride,carbonous sodium alum,potassium sulfate,sodium oxide,metal bromide,boraxTo prevent ecological environment from destroyed,we′ll have to use scientific methods and advanced technologies and to take a comprehensively developing wayIn view of this idea,the technological process of which hydrous magnesium chloride is used for production of metal magnesium is expoundedAt the same time,a combined flowsheet for producing high purity magnesia and metal magnesium by the amine precipitation is discussed
