Welcome to CDC stacks Copper extraction from aqueous

In single-stage extraction tests, emulsion membranes extracted up to 94 pct of the copper from solutions without pH adjustment, and 99.7 pct when the pH was maintained at about 2.5. Simulated two-stage crosscurrent and countercurrent circuits extracted all but 3 and 4 ppm of the original copper content, respectively.
