Ion exchange resin for gold adsorption Hydrolite ZGA408 Au

To order

ZGA408 Au is a specialty resin developed by Hydrolite for gold recovery in the hydrometallurgical industry.
It is a macroporous weakly basic anion exchange resin. Thanks to the special matrix, ZGA408 Au has great mechanical strength and long-lasting anti-osmotic pressure against acids and alkalis, compared with other conventional weakly basic anion exchange resins.
In addition, ZGA408 Au has minimal wear resistance. The annual wear rate is less than 10%. Also, ZGA408 Au has a relatively large specific surface area, area and strong-weak functional group, has a large exchange capacity and fast exchange kinetics, and speed in the process of processing gold with leaching solution.
