The pilot line of Lenghu Gold-In Membrane New Material Co., Ltd., a wholly-owned subsidiary of Xi'an Gold-In Membrane Environmental Protection Technology Co., Ltd., located in the Lenghu Bindi Potash Fertilizer Plant in Qinghai Province, successfully extracted Lithium carbonate from the brine of Qinghai Lenghu Lake, where the lowest temperature reached minus 30 ℃, magnesium lithium reached 1300:1, and each liter of brine contained only 0.075 grams of lithium ion, and reached battery level once. The success of the pilot production line for extracting lithium from brine has solved a world problem of extracting lithium from low-grade brine, applied for more than 17 national invention patents, and the 50 ton/year pilot production line for Lithium carbonate from salt lake brine has been running steadily. Lenghu Gold-In Membrane New Material Co., Ltd. has carried out the construction of the 10000 ton/year battery grade Lithium carbonate project in Cold Lake, Qinghai Province.

Team advantage：

The company relies on the advantageous disciplines of XAUAT to undertake national, provincial, and ministerial natural science fund projects, as well as the construction of key laboratories and research and development platforms, laying a solid foundation for the sustainable development of the company. The research team includes one academician (consultant) of the CAE Member, one Shaanxi Provincial Hundred Talents Plan, seven professors, 15 associate professors, 10 senior engineers, and more than 100 doctors and masters.

Technical advantages:

The Solid-Phase Ion Binding Technology (SPIB) independently developed by the company has large adsorption capacity, high analytical adsorption efficiency, strong selectivity, short adsorption and analysis cycle, and its comprehensive performance is about 30 times that of other companies; Based on the above key core technologies reaching international advanced levels, China's salt lake lithium extraction technology has significantly improved overall, and also has strong international market competitiveness, forming a "magnetic point" to attract investors.

Resource advantages：

1.Lenghu Bindi Potash Fertilizer Co., Ltd. has a mining title of 832 square kilometers in the Kunteyi deposit. The company has signed a cooperation agreement with Bindi Potash Fertilizer, which will provide us with all the brine generated from its salt fields;

2.The company signed an investment cooperation agreement with Qinghai Zhong tian Boron Lithium Mining Co., Ltd., and both parties gave full play to their respective advantages to invest resources and funds to build a 10000 ton Lithium carbonate brine lithium and boron extraction industrial project;

3.At the beginning of 2019, its subsidiary Haixi Yueshanda Membrane Separation Technology Co., Ltd. obtained the 307 square kilometer deep brine potassium ore exploration right in the western section of Ji'nai Lake in Dongtai, Haixi Prefecture, Qinghai Province.

In July 2019, the first phase of the battery grade Lithium carbonate production line with an annual output of 5000 tons/year has been completed, making the application of membrane separation technology in the recovery of valuable rare Recycling from the waste liquid of potassium extraction in salt lakes enter a new stage, and the foundation for creating greater environmental, social and economic benefits has been formed.
