PSI WP-1 Ion Exchange Resin

PRIMARY APPLICATION: Recovery of platinum and paladium from sub-zero pH liquors

At sub-zero pH, WP-1® will load Pt & Pd while rejecting all base metals and other impurities. As the resin is amorphous silica based, the loaded resin is suitable for sale to smelters thereby providing a cost effective process route for Pt & Pd recovery. Loading capacities are usually in excess of 150 mg/g. As an alternative of sale to smelter, the precious metals may be eluted from the resin. Please contact PSI for technical advice on this processing route.

SECONDARY APPLICATION: Transition metals recovery

WP-1® resin will load Cu+2, Ni+2, Co+2, Zn+2, Fe+2, Fe+3, Mn+2 and Al+3 from process liquors in the pH range of 3 to 10 and is especially effective where dissolved chelators, such as EDTA, are present in the feed liquor. As is common with all of the Purity Systems Inc. range, WP-1® will reject sodium, potassium and calcium +2 ions.

Resin performance and selectivity in a mixed metals matrix may vary according to the composition and tenors of the liquor, the pH, and the actual process conditions. We recommend testing on the actual process liquor in order to assess resin suitability.
In some instances separation of the loaded metals may be possible. Environmental clean-up projects may be potentially cash flow positive through the recovery and sale of high purity value metals.
