Jiuwu Hi-Tech Helps China's Salt Lake Create the World's First Industrial Benchmark for Raw Brine Adsorption

On March 8, the third phase of the technical modification project of the China Minmetals Lithium Extraction from Salt Lake at Yiliping successfully completed its trial run, marking a significant breakthrough for the world's first industrial project utilizing original brine adsorption. As the technical service provider for the core process section of this project, Jiuwu Hi-tech injected technological momentum into this milestone project with its solid and reliable "adsorption + membrane" integrated technology, assisting China's salt lake lithium extraction technology in advancing to a new stage of "high efficiency, low carbon, and intelligence".

World's First Innovation: Breaking Through Technical Bottlenecks

This technical modification project employs China Minmetals Salt Lake's independently developed "original brine efficient lithium extraction technology," which improves the comprehensive recovery rate of lithium by nearly 100% through adsorption process innovation, significantly shortens the production cycle, and is expected to increase annual lithium carbonate production capacity by 15,000 tons. As the key support provider for the industrial implementation of this technology, Jiuwu Hi-tech deeply participated in the entire process of technical validation:

Full-cycle Technology Empowerment

Provided process package development support throughout the process, from lab-scale parameter optimization, pilot plant verification to industrial scale-up design.

Breakthrough in Core Materials

Custom-developed specialized adsorbents suitable for high sodium-to-lithium ratio original brine, with a cumulative filling volume of 1710m³ (accounting for 75% of the total adsorption section volume).

Process System Integration

Completed the full-process design of the membrane separation system, constructing an adsorption-membrane coupled lithium extraction technology system.

Overcoming Extreme Cold: Forging Excellence with Iron Will

Faced with the extremely cold environment of -20°C and the stringent requirement to complete before the Spring Festival, the Jiuwu team demonstrated strong execution capabilities:

• Round-the-clock Battle: Formed a specialized task force working an average of 16 hours a day, setting a new industry benchmark for adsorbent filling efficiency.

• Smart Construction: Employed modular pre-filling processes to overcome the challenge of auxiliary materials solidifying during winter construction, achieving a 100% compliance rate for key parameters.

• Full-process Escort: Dispatched process experts for on-site commissioning to ensure the adsorption section passed the continuous operation test in one go.

Collaborative Innovation: Shaping a New Industry Benchmark

As a long-term technical partner of China Salt Lake, Jiuwu Hi-tech has always practiced the cooperation concept of "technology first, service support":

• Process Optimization: Participated fully in the design and parameter optimization of the original brine lithium extraction process route.

• Intelligent Control: Developed an automated control solution to ensure stable industrial production operation.

• Low-carbon Design: Supported the achievement of clean production goals through the energy efficiency optimization of the membrane system.

From Qarhan to Yiliping, from thousand-ton pilot scale to ten-thousand-ton mass production, as one of the few China providers mastering the entire process of "adsorption + membrane" salt lake lithium extraction core materials, process technology, and commissioning, Jiuwu Hi-tech will continue to deeply assist in the technological upgrade of salt lake lithium extraction. In the future, we will continue to collaborate with China Salt Lake, leveraging technological innovation to promote the transformation of resource development models, and contribute Jiuwu's wisdom to building a world-class salt lake industrial base!
