Pulsed Column Application In Copper Solvent Extraction

The advantages of using vertical pulsed columns as replacements for conventional mixer/settlers in the uranium industry have been known for some time. The advantages of the columns offer include a reduction in real estate for the plant, elimination of diluent evaporation and crud formation. This paper presents the findings of laboratory tests of pulsed columns extracting copper from pregnant leach solutions and also discusses potential advantages of the pulse column in copper solvent extraction.
