WebThe pregnant leach solutions from leaching are too dilute, (1–5kg Cu2+ m −3) and too impure for direct production of high-purity cathodes. Electrowinning from these solutions would give dendritic, soft, and impure copper deposits. Solvent extraction provides the means for producing pure, high-copper electrolytes from dilute, impure pregnant ...
