Abstract

Email to a Friend
Lignin sulphonic acid (or its salt) is commercially used as a surfactant in the Zinc Pressure Leach process. The surfactant prevents liquid sulphur from coating unreacted zinc minerals thus allowing the leaching reaction to proceed. Infrared studies have been performed using the Attenuated Total Reflection-Fourier trans- form infrared technique (ATR-FTIR); the application of this technique permitted the "in-situ" study of the adsorption of the surfactant by sphalerite. The spectral records obtained from study indicate that the lignin sulphonate ions are both physically and chemically adsorbed by the sphalerite.
