Addressing the challenges of high magnesium-to-lithium ratios and low-grade salt lake development, Chonfar has introduced an aluminum-based adsorbent with independent intellectual property rights. It achieves a saturated adsorption capacity of ≥4.5g/L, a working adsorption capacity of ≥2.1g/L, a desorption rate of over 90%, and a dissolution loss rate of less than 6% per year, reaching industry-leading levels and breaking through traditional process barriers. This adsorbent features strong adsorption capacity and low-temperature resistance, with superior product performance. Application areas include salt lake brine, oil and gas field brine, deep underground brine, lithium iron phosphate, and lithium battery recycling. The aluminum-based adsorbent has been officially deployed in a lithium extraction project from oil and gas field water, achieving large-scale production of lithium carbonate from oil and gas field water. It provides a dual solution for "diversified lithium resource development + resource utilization of oil and gas field wastewater."
