As a leading provider of separation and purification materials and solutions in China, Sunresin has successfully industrialized the Seplite® resins as well as the Sepsolut® SMB system for steviol glycoside purification in various EPC projects since 2009. While improving product quality, Sunresin’s technology also improves production efficiency and reduces cost, thus promoting the technological upgrading in the whole stevia industry.

Vanadium is a silver-white refractory rare metal. It is ductile, hard, non-magnetic, and resistant to corrosion. Given its stable features in alkali, sulfuric acid and hydrochloric acid, it is widely used in machinery, automobile, shipbuilding, railway, aviation, bridge, electronic technology, national defense and other industries.

In the purification process, Sunresin’s uniform-particle-size ion exchange resin, specifically developed for lactic acids, removes impurities, ashes and proteins from the lactic acid fermentation broth, in order to provide high-quality raw materials for the synthesis of polylactic acid.

As a rare metal with high energy density, cobalt is an important element of ternary batteries. With the rapid development of the Electric Vehicles industry, the supply-demand relationship of cobalt has been tight for a long time. Congo (DRC) is a cobalt-rich country with its output accounting for up to 70% of the global output.

In the chlor-alkali industry, the use of ion-exchange membrane electrolyzers to produce sodium hydroxide has become a common practice. However, this membrane method requires that the content of calcium and magnesium ions in the brine into the tank be less than 20ppb. The old refining method can only reduce the content of calcium and magnesium ions in the brine to about 1 ppm.

Sunresin has over 10 years' experience in Direct Lithium Extraction and has its footprint in brines from Qinghai (China), North America, Europe as well as South America. With its adsorption technology, the company has provided one-stop-shop services to project owners covering project conception and supply of adsorption materials and equipment. Customized solutions and products have been tested successfully with different levels of brine under different conditions across the globe.

On the evening of January 3, 2022, Sunresin New Materials issued an announcement indicating the “Receipt of the Signing Notice” from Jinhai Lithium Industry (Qinghai) , a subsidiary of the Huizhou Yiwei Lithium Energy Co., Ltd, on the 10,000 ton lithium carbonate EPC procurement project. The tentative amount of the project is about 456.11 million RMB (71.8 million USD).

Sunresin’s Ruashi project features the extraction of cobalt from the precipitation liquor of cobalt hydroxide. The project included a collaborative effort with Sunresin’s Remote Solution Operation and Monitoring Center (RESOM) in Xi'an, an innovative initiative put in place during the lockdown period in 2020 to serve domestic and international EPC projects.
