| Abstract: | Up to now Qarhansalt lake is the largest potassium&magnesium salt mine for its proved reserves in China.It is well known as the"cradle"of Chinese potash fertilizer industry and has made great contributions to China's food security program over the past 62 years,in which the industrial chain of new energy and new materials is under construction.For more efficient development and utilization of salt minerals in Qarhan salt lake,the development course was briefly reviewed in this paper,state-of-art technologies and industries for upgrading low-grade potassium-bearing ores,comprehensive utilization of tailings,development of potash resource associated with magnesium and lithium were summarized.Some suggestions on technological innovation and industrial development in the future were proposed. |
