Copper Recovery

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.
