Titanium-based Lithium Adsorbent G-100 is an ion sieve made of titanium dioxide based material with stable crystal structure and three-dimensional ion exchange channels. It has very strong selectivity to lithium ions in terms of ionic radius and valence state, however rarely adsorbs other cations such as magnesium, sodium, potassium, boron and calcium in the brine. It has the characteristics of easy desorption, small dissolution loss, high concentration of elution. It can be repeatedly regenerated, repeated use, long service life. It can be used to fill the adsorption tower for lithium extraction, and the process is simple. Its unique particle size distribution and morphology makes the water flow resistance through the tower is small, the liquid flow smoothly even for the high viscosity concentrated brine.
Titanium-based Lithium Adsorbent G-100
----Specially Researched, Developed and Manufactured for the Development of Extracting Lithium from Salt Lakes
Titanium-based Lithium Adsorbent G-100 is widely used as lithium adsorbent in lithium extraction and recovery such as:
◆ Carbonate-based alkaline brine
◆ Sulfate brine
◆ Chloride brine
◆ High magnesium-lithium ratio brine
◆ Lithium-bearing geothermal brine
◆ Oil and gas field wastewater containing lithium resources
◆ Lithium sink mother liquor in lithium salt production process
◆ Lithium recovery from used lithium batteries
