Zangge Lithium Wins Recognition for Technical Support in Tackling a World-Class Lithium Extraction Challenge

       The letter noted that, during the key stages of Phase I production and operations at Laguo Resources and the customization of the lithium extraction process for Phase II, the project faced a number of common industry challenges, including elevated impurity ion levels in the qualified titanium-based solution, silicon contamination of nanofiltration membranes, and fouling of homogeneous membranes.

       In response, the technical team from Zangge Lithium, led by Li Jianchang and Zhu Hongwei, proposed an innovative “titanium-based plus aluminum-based” process solution. This enabled the successful industrial application of the world’s first titanium-aluminum composite salt lake lithium extraction unit, which subsequently reached its designed production capacity.

       Since 2025, Zangge Lithium has continued to dispatch professional technical teams to the frontline production site on the plateau. Through hands-on operational guidance, standardization of laboratory testing procedures, review of operating protocols, and resolution of technical issues, the Company has supported the rapid capability building of the Laguo Resources team and helped its production operations and management move toward greater standardization.

       At the end of February 2026, an unexpected fault occurred in the electrical system of Laguo Resources’ electrodialysis workshop, creating a risk of significant production losses. Zangge Lithium responded immediately by urgently coordinating key materials and dispatching experienced experts to provide on-site support. The team quickly restored the operation of the bipolar membrane system, providing timely and critical assistance to safeguard the continuity of production.

       In early April this year, the Laguo Resources team visited Zangge Lithium for an exchange and site visit. Upholding an open and collaborative approach, the Company systematically shared the core technologies, practical experience, and optimization directions of its aluminum-based lithium extraction process. Through in-depth technical explanations and on-site demonstrations, Zangge Lithium demonstrated its technical expertise and commitment to knowledge sharing and industry collaboration.

       From technical problem-solving to on-site support, from emergency assistance to experience sharing, Zangge Lithium has continued to provide in-depth support to Laguo Resources with its solid technical capabilities, rigorous professionalism, and sincere approach to cooperation, helping the company overcome technical bottlenecks and improve its operational performance.

       A letter of appreciation is both recognition and motivation. Going forward, Zangge Lithium will continue to uphold the spirit of perseverance and innovation, work hand in hand with industry peers, and jointly promote the high-quality and sustainable development of China’s salt lake lithium extraction industry.
