Solvent Extraction and Separation of Copper and Zinc

2012-1-2 · : Solvent Extraction and Separation of Copper and Zinc from a Pickling Solution . During extraction of metals using acidic extractants, H + ions are released causing the decrease in pH which subse-quently lowers extraction of metals in several instances. So the extraction process is greatly affected by pH. The effect of
