Recovery of copper and zinc from mine waste effluents with carboxylic-type ion-exchange resins: M34-20/127E-PDF

“The recovery of copper and zinc from synthesized mine waste effluents containing up to 7.0 g/l of total metal with the Rohm and Haas Limited carboxylic-type resins Amerlite IRC 50 and IRC 84 has been investigated. The adsorption characteristics of the resins from the Na+, NH4+ and H+ forms at feed pH values of from 3.6 to 6.0 were determined. The results of the work showed that under all conditions investigated the metals broke through very early in the adsorption cycle. An ion exchange operation run under these conditions to produce an effluent containing <0.1 ppm of metal could be expensive, due to high capital cost in equipment and resin inventory"--Abstract, p. i.
