Precious Metal Recovery Resin
INQUIRY
With the increase of industrialization, the demand for precious metals such as gold, silver, and platinum has skyrocketed. However, extracting these precious metals from their ores is not only a costly process but also has a significant impact on the environment. As a result, researchers and scientists have been exploring innovative ways to recover these precious metals from electronic waste and industrial byproducts.
Precious metal recovery resin, as a special type of resin, is now widely used in the precious metal recovery industry. The resin offers a clean and sustainable solution that minimizes the environmental impact while maximizing metal recovery rates.
Mechanism of Action
At present, there are many studies on the recovery of precious metals by ion exchange resin. Different types of resins can be used to recycle precious metals, such as cation exchange resin and anion exchange resin. Their mechanism of action is as follows:
- Hydrogen ions on the cation exchange resin undergo an ion exchange reaction with the precious metal ions in the solution, thus realizing the adsorption of precious metals.
- The adsorption of precious metals by anion exchange resins belongs to anion complexation exchange reactions. The resin is protonated in an acidic medium, and the cationic group formed combines with the complex anion of the precious metal by electrostatic attraction between ion pairs to achieve the purpose of adsorption.
