Precious Metal Recovery

Precious metals are widely used in electroplating and other hi-tech manufacturing. Precious metals are also mined from leaching solutions and from seawater. Ion exchange resins are commonly used to remove trace levels and to concentrate precious metals. The metals are then recovered by various specialty regeneration techniques or by incinerating the resin.

ResinTech makes a variety of ion exchange products that are used for precious metal recovery and for solution mining. These products include the Thiol and Thiol-uranium functional resins, as well as the more conventional strong acid and strong base resins and granular activated carbon.

AGC-30 CS Coconut shell carbon used for concentration of gold cyanide.
