Da Qaidam Salt Lake is a large-scale comprehensive deposit mainly composed of solid boron ore, rich in boron, lithium, potassium, magnesium, and coexisting solid and liquid. It is mainly composed of lake chemical sedimentary ore and lake marsh sedimentary ore. Liquid ore is composed of intergranular brine ore and surface lake water ore, which contain resources such as sodium, potassium, magnesium, boron, and lithium.

The brine in the mining area is rich in lithium. In order to make full and efficient use of salt lake resources and develop towards high-tech direction, Xi'an Gold-In Membrane Environmental Protection Technology Co., Ltd. and Qinghai Zhongtian Boron Lithium Technology Co., Ltd. jointly funded the establishment of Qinghai Zhonglixin Membrane Technology Co., Ltd., which is located in the Dachaidan Executive Committee of Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai Province.

Advantages of both parties:

Qinghai Zhongtian Boron Lithium has the resource extraction rights and related infrastructure advantages of the Dachaidan Salt Lake. Relying on the basic research team of the parent company and the advantages of membrane material application technology, the Cold Lake Gold Deposition Membrane has developed efficient and environmentally friendly adsorption and membrane separation core technology for lithium extraction from salt lake associated minerals, and has rich industrialization experience.

Both parties complement each other's joint advantages by fully leveraging their resource advantages and independently developed salt lake lithium extraction technology, forming a high point in the core technology of salt lake brine lithium extraction, making the joint venture a leading salt lake brine lithium extraction and comprehensive development platform.
