The following is a summary of the results obtained. (1) Although the zeta-potential of chromites is influenced by gangue minerals accompanying them and the existence of metal ions in the chromite-water system, the i.e.p. (isoelectric point) of pure chromite which has a fresh surface is around pH 8.0 regardless of chemical composition.
