SX Solvent Extraction Process Principles Theory
Because of the design of mixers currently used in copper solvent extraction plants, metal transfer in a stage is usually about 85 to 95% of theoretical. For this reason, the values predicted by equilibrium McCabe-Thiele diagrams for the aqueous and organic phases exiting a given stage are seldom realized in an operating circuit.
