A study has been made of the rccovery of copper (11) by solvent extraction with Alamine336 (Tri-n-oclylamine) as a extractant from hydrochloric etching solutions. The effect of extractant concentrations, hydrochloric acid, chloride Ion concentrations and phase ratio (organiclaqueaus) on copper extraction were studied. Experimental results showed that the concenl~atiano f extractant and the phase ratio strongly influenced the copper extraction, and the extraction percent of capper Increased at higher hydrochloric acid and chloride ion mncmhation. We proposed that the optimum extrachon stages of copper for continuous extraction process by analysidng thc McCabe-Thielc diagram. Stripping of copper from the loaded organic phases wn be accomplished by pure water (H, O) as a dripping reagent effectively. As the tcmpcrature is increased, thc stripping of copper is enhanced.
