China News Agency, Qinghai Delingha, March 25 (Sun Rui) "Today, China's largest brine extraction project-Qinghai Salt Lake Fozhao Lanke Lithium Co., Ltd. 20,000 tons/year battery grade lithium carbonate project officially officially Resumption of work is expected to be completed on September 30 this year." Qinghai Salt Lake Fozhao Lanke Lithium Co., Ltd. Chairman He Yongping said on the 25th in Golmud, Qinghai Province.

　　On the same day, the first batch of projects in Haixi Prefecture, Qinghai Province will resume work in 2021. The largest lithium extraction project in China-Qinghai Salt Lake Fozhao Lanke Lithium Industry Co., Ltd. 20,000 tons/year battery-grade lithium carbonate project officially resumed work.

　　He Yongping introduced that the Chaerhan Salt Lake in Golmud has a total area of ​​5,856 square kilometers and various resource reserves of more than 60 billion tons.

Among them, 540 million tons of potassium chloride and 12.04 million tons of lithium chloride rank first in China, with a potential economic value of tens of trillions (RMB, the same below).

　　In the past ten years, the company has shifted from traditional potassium extraction to lithium extraction and other strategic emerging industries such as new energy and new materials, and has successfully overcome the worldwide problem of "extraction of lithium from brine with high lithium/magnesium ratio by adsorption method".

At present, a 10,000-ton/year lithium carbonate device has been built to realize industrial production.

　　The project was filed in December 2017, with a total investment of 3.132 billion yuan.

The construction content of the project mainly includes the adsorption lithium extraction tower area and upstream devices (salt fields and storage tanks), nanofiltration reverse osmosis, lithium precipitation, adsorbent synthesis and other devices, as well as supporting auxiliary production projects, public engineering projects (natural gas boilers, Air compressor station, circulating water station, chilled water station, main substation, etc.), administrative service facilities, etc.

After the project is completed, it can achieve an annual production scale of 20,000 tons of battery-grade lithium carbonate, and an annual production capacity of 30,000 tons of lithium carbonate.

The project started construction on April 18, 2018. As of now, the investment has been about 1.7 billion yuan, and the overall progress of the project is 85%. It is expected that the test run will be completed on September 30, 2021.

　　"After years of development, the Haixi salt lake industry has reached a new level of comprehensive utilization and large-scale production, and has overcome nearly 100 major technical problems such as reverse flotation cold crystallization and high magnesium-lithium ratio salt lake lithium extraction. The salt chemical industry system We are advancing in the direction of multi-industry integration and linking. The energy consumption, water consumption and pollutant emission intensity of unit products have reached the international advanced level, and the industrial scale and development capacity have been significantly enhanced. The basic conditions for building a world-class salt lake industrial base are now available. Said Jiang Jun, deputy governor of Xizhou.

　　Jiang Jun said that today, the salt lake industry has become the most distinctive and important core industry of the Haixi industry. During the "14th Five-Year Plan" period, Haixi will make every effort to build a world-class salt lake industrial cluster, optimize the spatial layout of the salt lake industry, and promote the construction of smart salt lakes.
