solvent extraction of copper in the lab

Copper Recovery by Solvent Extraction Techniques

Feb 02, 2017  The extraction section of the solvent extraction plant consists of a number of mixer-settlers in series. The aqueous leach liquor flows through these counter-current to an organic stream which is made up of LIX 64N dissolved in a kerosene carrier, and the copper content of the leach liquor is transferred into the organic phase.
