Direct Lithium Extraction (DLE)

Sunresin is the major DLE lithium sorbent producer in China which mainly used for extraction lithium from salar brine and geothermal brine etc with high efficiency.
Besides DLE sorbents,Sunresin is the solution provider which supply the whole EPC solution from brine to finished product(Lithium carbonate or lithium chloride )

Sunresin could build and deliver the plant including design, equipments, sorbents, installation guidance, pilot running and training etc.
Generally saying, we supplied the whole lithium plant which ready to use.

Till 31th March, 2022, sunresin took 9 commercial DLE projects. (3 installed+1 installing+5 new projects)
For all the nine contracts received, it could contribute a total capacity of 73,000 tons of lithium carbonate and lithium hydroxide
For other lithium sources( spodumene, clay and lapidolite etc), sunresin was mainly involving in impurities removing jobs like Ca, Boron removal etc.
Below is the overview of sunresin salar brine lithium projects till 31th March, 2022
We summary sunresin strength for Li with details as below:
Generally sunresin has been trying to optimizing the performance from overall project for many years:
For Ca, Mg and boron removal(impurity polishing), sunresin also dominated the market in China.

Advancing Ergothioneine Biosynthesis through Adsorption and Separation Technology

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.
