Qinghai News, June 7 (Xinhua) (Ge Xuan, Li Shasha) Since then, Golmud has been closely relying on its resource advantages, starting from a drop of brine, actively promoting the cascade development of potassium, sodium, magnesium, boron and other resources and the comprehensive utilization centered on chlorine balance, continuously improving the efficiency of comprehensive utilization of salt lake resources.

Golmud City has always adhered to the national strategy of promoting the comprehensive utilization of salt lake resources as the goal, and promoted the serialized, high-quality and diversified development of salt lake chemical industry. It has basically formed a circular economy industrial system dominated by large-scale potash fertilizer, supplemented by sodium salt, magnesium salt and lithium salt. We will strengthen the factor guarantee of salt lake enterprises, accelerate the drive ability of scientific and technological innovation, and establish four national science and technology platforms, seven provincial engineering technology research centers, two key laboratories, two Business incubator and other research institutions, including the national innovative salt lake industry cluster pilot, the national engineering technology research center for comprehensive utilization of salt lake resources. Breaking through the technology of potassium and lithium extraction, accelerating the integration and integration of the potassium fertilizer industry with industries such as chlor alkali and metallurgy, and forming a preliminary technological innovation system for circular economy industries represented by salt lake magnesium, lithium, potassium, and chlorine chemicals. At the same time, we will continue to increase investment and investment attraction efforts, focusing on salt lake resources and existing industrial foundations. We will seize the opportunity of a new round of eastern industrial transfer, carry out targeted industrial project promotion negotiations, fully leverage the investment role of "attracting business and enterprises", and fully support existing enterprises to grow and strengthen, introduce industrial supporting facilities and downstream deep processing projects, and form an industrial cluster effect. In 2022, a total of 3 salt lake industry projects were signed with a contract amount of 4.15 billion yuan, fully leveraging the advantages of salt lake resources and promoting high-quality development of the salt lake industry.

Adhering to the goal of building a world-class salt lake industrial base, we strive to promote the serialization, high-quality, and diversified development of the salt lake chemical industry. By 2025, the allocation of salt lake resources will be further optimized, industrial development policies will be more sound, and new achievements will be made in "strengthening, extending, and supplementing the chain". The orderly development and utilization of valuable components of salt lake resources will be promoted, and new achievements will be made in the construction of industrial innovation carriers, A relatively smooth production factor guarantee system has been established, and the construction of salt lake advantageous industrial clusters, important product production areas, circular economy demonstration areas, technological innovation sources, and industrial talent training areas is steadily advancing. The output value of the salt lake industry is expected to exceed 34 billion yuan, and the construction of world-class salt lake industrial bases will see initial results.
