Titanium-based Lithium Adsorbent G-200
The G-200 titanium-based Lithium Adsorbent is our company’s second-generation lithium extraction material. It can adsorb lithium ions from various solutions and features a stable crystal structure and three-dimensional ion exchange channels. It demonstrates strong selectivity for lithium in terms of ionic radius and valence state, with minimal adsorption of cations such as magnesium, sodium, potassium, boron, and calcium from brine. It features easy desorption, minimal dissolution loss, and high elution concentration. The material can be repeatedly regenerated for long service life. It is suitable for filling adsorption towers for lithium extraction, ensuring a simple process. Its unique particle size distribution and morphology reduce water flow resistance through the tower, allowing for smooth liquid flow even with high-viscosity concentrated brine.

Titanium-based Lithium Extraction: A New Frontier in Lithium Recovery Technology
Lithium, a critical component in the renewable energy sector, particularly for batteries, is traditionally extracted from brines using various methods, including chemical precipitation, solar evaporation, and membrane filtration. However, the Direct Lithium Extraction (DLE) process using adsorbents offers a more efficient and environmentally friendly approach. Among the materials used for DLE, titanium-based adsorbents, such as the Titanium-based ion exchanger G-200, are emerging as a significant innovation, challenging the established aluminum-based and manganese-based adsorbents.
Aluminum-based Adsorbents
Aluminum-based adsorbents have been a reliable choice for industrial lithium extraction from chloride-type brines with high magnesium to lithium ratios. Their primary advantage lies in their suitability for large-scale production and their environmental friendliness due to good selectivity. However, they fall short in several areas: they consume significant amounts of fresh water, have small adsorption capacity, require the construction of large-scale adsorption towers, and perform poorly in alkaline brines or those with high sulfate ion concentrations.
Manganese-based Adsorbents
Manganese-based adsorbents perform well in neutral and alkaline brines and are suitable for low pH conditions. They offer high adsorption capacity and selectivity. Despite these benefits, their major drawbacks include high dissolution loss rates during the desorption process and poor cycle life and stability, which limits their practical application and increases operational costs.
Titanium-based Adsorbents: The New Contender
Titanium-based adsorbents, particularly the G-200 model, represent a newer and more robust approach. They are suitable for a wide range of brine types and maintain high adsorption capacity and selectivity. The G-200 adsorbent is especially notable for its low dissolution loss rate, making it more durable and efficient. It also offers a higher concentration of lithium in the desorption liquid, which simplifies the extraction process and reduces costs associated with concentration equipment.
The G-200 adsorbent exhibits several distinctive advantages:
High Efficiency: It boasts a dynamic adsorption capacity of up to 14.02 mg/g, with lithium concentration in elution reaching up to 15.4 g/L.
Selective Adsorption: It has a high rejection rate of magnesium (99.83%) and other competing ions, ensuring that lithium is selectively extracted.
Environmental Benefits: The process associated with titanium-based adsorbents generates less waste and is less harmful to equipment.
Operational Stability: It supports a long operational lifecycle with minimal degradation in performance, evidenced by successful repetitive cycling tests.
Cost-effectiveness: Despite a slightly higher initial cost compared to manganese-based adsorbents, the overall operational and maintenance costs are lower due to its higher stability and efficiency.
Conclusion
While aluminum and manganese-based adsorbents have their merits, titanium-based adsorbents like G-200 are paving the way for more sustainable and cost-effective lithium extraction processes. As the demand for lithium grows, especially for battery production, the development of more advanced extraction technologies like titanium-based adsorbents is crucial. These materials not only enhance the efficiency of lithium recovery but also align with environmental sustainability goals, making them a pivotal technology in the transition to green energy.
