The adsorption coupled membrane process is one of the most promising technologies for lithium extraction from salt lake brine, with advantages such as high efficiency, energy conservation, environmental protection, and simple operation. However, the core material adsorbent often has problems such as low adsorption capacity, poor selectivity, and high loss rate, which limits the application of this technology. Through long-term technological breakthroughs, Jiuwu High-Tech has greatly improved the performance of adsorbents. It has taken the lead in developing titanium-based and aluminum-based lithium adsorbents, with high mass transfer efficiency and fully independent intellectual property rights. We have also built 6000 tons per year adsorbent production lines of the project, achieving a three-step strategy of investment, production, and sales for the same year. In the future, our production lines will be expanded in a timely manner based on the market demand for lithium extraction from salt lakes, further to enhance the capacity of adsorbents.
