SX Solvent Extraction Process Principles Theory

A high copper/nickel ratio on the copper loaded organic is obtained by using an extra extraction stage in which copper crowds nickel from the loaded organic, i.e., the copper in an ammoniacal copper and nickel containing solution, when contacted with an organic loaded with nickel, will replace some of the loaded nickel. After the copper and nickel are loaded in separate extraction operations, each “metal loaded organic” is washed and then stripped to give a copper
