On September 21, Jintai Lithium Industry’s Phase-Two 4000t/a lithium carbonate project undertaken by Sunresin started production. Up to now, Sunresin has completed an accumulated 7000t/a lithium carbonate for Jintai Lithium Industry.
Since 2018, Sunresin has successively signed 3000t/a and 4000t/a salt lake lithium extraction projects with Jintai Lithium Industry, providing full-process technical operation services using its Direct Lithium Extraction (DLE) technology. The Phase-One 3000t/a lithium carbonate project has been put into operation successively in 2018 and is currently running well. In September 2021, Sunresin and Jintai Potash Fertilizer carried out strategic cooperation, and simultaneously started the construction of the Phase-Two 4000t/a lithium carbonate project.
Jintai’s 4000t/a lithium carbonate project is a major salt lake lithium extraction project designed, developed, constructed, commissioned and put into operation by Sunresin Technology in a one-stop shop fashion, including all processes from brine to lithium carbonate.
Compared with the completed Phase-One 3000t/a Lithium Carbonate Project, the adsorption process and the production capacity of a single unit have been optimized, and the connection method of the subsequent adsorption sections has been adjusted, making the overall system operation more efficient and smooth.
The commissioning of Jintai Lithium’s Phase-Two 4000t/a DLE project adds to the Phase-One 3000t/a project, also completely undertaken by Sunresin, to a total of 7000t/a, making it one of the leading suppliers of lithium salts in the Qinghai province.
In 2022, Sunresin has achieved a number of DLE projects including 4,000t/a of Minmetals Salt Lake, 6,000t/a of Jwell New Materials, and 4,000t/a of Jintai Lithium with guaranteed quality. The delivery of the Phase-One equipment for the Tibet Summit’s DLE project in Argentina has also been completed.
So far, thanks to over 10 years of experience in DLE, Sunresin has executed nine commercial DLE contracts representing a total capacity of 73,000 tonnes per annum of lithium. Sunresin's Direct Litium Extraction (DLE) technology has high recoveries with low costs and expedited processing times. It does not use any solvent and is more eco-friendly for sustainable development.
The adsorption and separation technology that Sunresin is engaged in is a highly efficient separation and purification platform technology with strong environmental friendliness, high automation, and good operational accuracy. As a leading global company in the adsorption and separation technology industry, we have been actively considering how to integrate our more than 20 years of research and development accumulation and technological advantages in the field of adsorption and separation with the national carbon neutrality path to contribute to the achievement of the dual-carbon goals and help optimize and upgrade downstream application processes.
Sunresin has developed Uniform Particle Ion Exchange Resin using targeted research and development, advanced chromatographic equipment, and strict quality control, utilizing new synthetic biology technology. This resin is designed to address the impurities and high salt content of existing fermentation processes used to produce ergothioneine. It is used for chromatographic desalination, decolorization, and purification, achieving an inorganic/organic salt removal rate of over 95% in high salt systems, reducing conductivity to below 50μs/cm. Moreover, the uniform particle characteristic of the resin allows for lower pressure drop in the resin bed, larger online liquid processing capacity, lower resin breakage rate, and better impurity and salt removal compared to conventional resins. This results in higher yields and significantly improved production efficiency, while reducing production costs.
To meet the high requirements of enterprises for fluoride content in wastewater and residents' demand for fluoride-free drinking water, Sunresin's research team has continuously researched, developed, and improved targeted adsorption fluoride removal resins LSC-760 and LSC-860 based on the typical industry wastewater quality and treatment process characteristics.
