LIX 64 alone was able to extract copper selectively from iron in the pH range 1.5-2.5, but with the disadvantage of slow rate of extraction. This was solved by the addition of a small amount of LIX 63. The mixture, LIX64N, for many years was the extractant of choice for commercial copper extraction from acidic leach solution (Szymanowski, 1993).
