The Chinese salt lake resources are exploiting currently in a large scale along with the development of Chinese economy and the effectively performance of the police of west great development. The paper demonstrates the relative technologies of exploiting salt lake resources in oversea and China, and introduces the developing status of potash, lithium salts and magnesium industry. The paper also proposes some suggests about reasonably exploiting salt lake resources in the light of principles of sustainable development and comprehensive utilization of resources.

Contents
1 New stage of large exploitation of Chinese salt lake's potassium resources
1.1 Demand of potassium
1.2 Status of potassium industry
2 A significant progress in the extraction of lithium from salt lakes
2.1 Demand and production of lithium
2.2 Breakthrough of the extraction of lithium from salt lakes containing high ratio of magnesium resources in Qinghai salt lakes
3.1 A new process for manufacture of anhydrous magnesium chloride from bischofite of salt lakes
3.2 Combination of manufacture of magnesium and chemical engineering of natural gas
4 Comprehensive utilization of resources as the base of exploitation of salt lakes

Key words: salt lake resources, exploitation, comprehensive utilization, potassium, lithium, magnesium
