Qarhan salt lake in qinghai province,with a total area of 5,856 square kilometers,is the largest salt lake in China and one of the most famous inland salt lakes in the world.Over the past 60 years,qarhan salt lake started from a drop of brine and insisted on"potassium based,comprehensive utilization and recycling development".The embryonic form of"ecological magnesium lithium potassium garden"gradually appeared.

Since the production of China's first bag of potash fertilizer in 1958,taet Lake Industry Co.,ltd.has never had a high level of research and development of potash fertilizer production technology.In 1997,a major breakthrough was made in the industrial application of the reverse flotation cold crystallization process independently developed by yanhu group.In 2000,the company formed the process software package and basic design of the 1,000,000 ton reverse flotation cold crystal technology potash fertilizer plant,which produced potash fertilizer and potassium chloride content not less than 95%.This project makes our country potash fertilizer production technology realized leapfrog development.

"We have a higher standard than national standards,"dou yongqin,director of the dry packaging workshop of potash corp.,told reporters.

In addition to potassium chloride,the qarhan salt lake also contains 12 million tons of lithium carbonate,half of the country's lithium resources.After more than 10 years of research and investment of more than 1 billion yuan to build an annual capacity of 10,000 tons of lithium carbonate device,has made breakthroughs in adsorption method,nanofiltration membrane and other technologies,has achieved the 10,000 tons of industrial scale production and battery level standards.

According to ma youjian,the marketing director of q4,q12,q12,q12,q12,q12,q12,q12,the company focused on lithium.Qarhan salt lake has 4 billion tons of magnesium chloride resources,accounting for 95%of the national resources."

In 2010,taht Lake Industry Co.,ltd.invested more than 6 billion yuan to build up a level of 100,000 tons of magnesium per year,which is the world's first set of 100,000 tons of magnesium from Salt Lake brine.

Qinghai salt lake magnesium metal magnesium plant project manager production factory director CheYongLin said:"the magnesium industry is a sunrise industry,because the metal magnesium production brine has characteristics of excellent and stable quality of green environmental protection,along with the progress of the magnesium alloy and its processing technology,the rising demand for light metal materials both at home and abroad,industry foreground is very wide."

Since the establishment of this factory in 1958,taet Industry Co.,ltd.has been enhancing science and technology and scientific research.Multiple measures are taken to make every effort to overcome difficulties,so that salt lake resources have been effectively protected,the production and ecological life of enterprises form a virtuous cycle,the company basically formed the prototype of"ecological magnesium lithium potassium park"development.
