Sunresin has recently signed the "Strategic Cooperation Agreement" with Chengxin Lithium Group Co., Ltd (SZ. 002240) in Chengdu, Southwest China. Zhou Yi, chairman of Chengxin Lithium, and Kou Xiaokang, general manager of Sunresin New Materials Co. Ltd., attended the signing ceremony.

Sunresin is pleased to announce it has recently entered into an MoU with ASX-listed mineral resources exploration company PepinNini for Evaluation and Development of the Salta Lithium Brine Project in the lithium triangle of north west Argentina - Sunresin

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.
