Abstract
In this research, a characterization of the chemical bleaching process of Colombian kaolin by potentiometric an galvanometric measures is shown. Three samples from La Unión, Antioquia (Colombia), were tested in laboratory taking into account the effect of the amount of reducing agent (Na2SO4) and the resident times. Phenomena description such as the variation in electrochemical potential, iron concentration in solution and the whiteness index evolution, contributes to the phenomenological analysis of kaolin processing. These results are important for future research works appointing to efficiency of Colombian kaolin blenching that make possible a reduction in precipitated iron species in mineral surfaces.
