Following the successful Ruashi cobalt extraction project in Congo DRC earlier this year, Sunresin has delivered another nickel and cobalt recovery project with overall solutions for Eti Gübre in Turkey. In the project, Sunresin used its adsorption technology to achieve the reuse of low-content cobalt-nickel tailings and achieved the separation of high-purity cobalt and nickel from low-concentration metal solutions, in an eco-friendly manner. Currently the project is in the commissioning phase.
ETI is a major chemical group in Turkey. With the rapid development of the global new energy sector and the tight supply of high-purity metals such as nickel and cobalt, ETI's mineral development and metal recycling departments have made continuous efforts to use the most effective and sustainable method to achieve its business goals.
As a leading company in adsorption technology from China, Sunresin has always had a good brand awareness and reputation in Turkey over the years. The overall solution of adsorption and separation technology provided for ETI in this project meets the customer's demand for high-quality products and sustainable development, which also marks another milestone for Sunresin’s international footprint in nickel and cobalt extraction solutions in a one-stop-shop fashion.
Macroporous adsorption resin is a kind of polymer resin with macroporous structure that does not contain functional groups such as exchange groups. It has a good mesh structure and a high specific surface area. Force or hydrogen bonding, selective adsorption of molecular organics in the liquid phase.
During synthetic processes, immobilized enzymes offer great advantages in terms of both operability and economy. In addition to ease of use, immobilized enzymes have the two main advantages of simple separation and reusability. After the reaction, it can be separated from the product.
In water treatment, ion exchange resins are often used to demineralize water where the cations are replaced by H+ ions and the anions are replaced by OH− ions. They are also used to soften water by replacing the cations (Mg2+, Ca2+) with sodium ions (and possibly the anions with chloride ions) of NaCl.
