  • Copper recovery using leach/solvent extraction

    Copper recovery using leach/solvent extraction/electrowinning technology 65 (Figure 2) and a catalytic amount of LIX 63, was introduced in 19657 and in March 1968 the first commercial copper L/SX/EW operation, the Bluebird plan of Ranchers Exploration and Development Corporation, came on line1 Copper recovery by L/SX/EX in 51Copper recovery by solvent extraction has progressed from a technology with limited application for copper recovery from dilute sulfuric acid leach solution to a technology with broad application for copper recovery from a variety of leach solutions Reagent improvements have led the way, but they have been accompanied by innovations in leachingCopper solvent extraction: The state of the art |What solvent extraction offered was the opportunity to produce cathode copper directly from the leach liquor on the same site as the leaching operation This gave advantages to both the large producer who would not have to consider extra smeltingCopper Recovery by Solvent Extraction Techniques
