Discussion on the Development and Technical Cooperation of Lithium deposits in Salt Lake in Argentina between Mount Qomolangma and Lanxiao Science and Technology

On August 16, 2021, Mr. Huang Jianrong, chairman of the company, met with Kou Xiaokang, general manager and Guo Fumin, deputy general manager of Xi'an Lanxiao Science and Technology New Materials Co., Ltd., and conducted in-depth discussions and exchanges on the company's development and technical cooperation in the salt lake lithium deposit in Argentina.

General Manager Kou Xiaokang first introduced the development process of Lanxiao Technology in the field of adsorption separation technology and the leading position and achievements of lithium extraction from salt lake by adsorption in China. In recent years, Lanxiao Technology has provided adsorbents and adsorption devices for Tibetan lithium industry 10,000-ton lithium carbonate project, Jintai 3000-ton lithium carbonate project and Minmetals Salt Lake 1000-ton project. at present, it is the only enterprise in China to provide multiple sets of successful industrialization projects in Salt Lake. In 2021, Lanxiao Technology also undertook the medium and small-scale test production lines of lithium extraction / impurity removal lines in lithium salt enterprises such as SQM and ANSSON (USA), and its adsorption and separation technology achievements have also been recognized overseas.

After listening to the introduction of Lan Xiao Technology, Chairman Huang Jianrong also gave a detailed introduction to the company's salt lake lithium mine project in Argentina. He said:

The company has the ANGELES (SDLA project in Salta province in northern Argentina) and ARIZARO two high-quality salt lake lithium deposits, with a total area of more than 400square kilometers. Among them, the lithium concentration of ANGELES salt lake is 600mg / L, the ratio of magnesium to lithium is less than 3.7and the proved lithium reserve is 2 million tons (lithium carbonate equivalent). The production capacity of 2500 tons of lithium carbonate using salt field evaporation and concentration process has been formed in the field. ARIZARO Salt Lake is currently under exploration and evaluation, and some data have shown that the concentration of lithium mineralization is between 30 and 979mg/L, and the ratio of magnesium to lithium is 14. It is inferred that it has great potential for lithium resources.

After listening to the introduction of Chairman Huang, the relevant leaders of Lanxiao Science and Technology believed that compared with the domestic salt lakes, the two salt lakes owned by the company have a large amount of lithium resources and excellent quality of resources. it will have a positive impact on the domestic lithium industry, especially the upstream resource demand in the future. Lanxiao Science and Technology believes that the domestic salt lake lithium extraction technology is currently in the forefront of the world, especially the adsorption separation lithium extraction technology has become the mainstream of brine lithium extraction and impurity removal. After further listening to the understanding of salt lake geography and basic suggestions, according to the previous analysis results of small-scale test data of similar salt lakes in Argentina, it is considered that the company's salt lakes can act as adsorption + membrane technology. Compared with the traditional salt field spreading method, it has the advantages of high recovery rate, short time to realize production capacity, no waste salt pollution and so on. According to the data provided by the company and the requirements of the products, the technical experts present a preliminary technical route and scheme, according to the experience of the industrial production line that Lanxiao has implemented, coupled with the experience of experimental data of salt lakes in South America, it is predicted that using a complete set of Lanxiao technology adsorbents and system equipment, the production capacity of 25000 tons (lithium carbonate equivalent) under the salt field evaporation process will have 30-60% room for improvement.

Finally, Chairman Huang said that the company has high-quality lithium salt lake resources, Lanxiao Technology has the leading technical force for lithium extraction from salt lakes in China, and the two sides can carry out cooperation on the previous trial scale. it also said that brine with different lithium concentrations and analytical equipment could be provided on the site, and it was suggested that the on-site salt field should be used to achieve a pilot scale at one time. It is hoped that the two sides will further and quickly carry out relevant work on the premise of complementary advantages and mutual benefit and win-win results.
