Abstract

Two natural clays extracted from soils of Colombia (department of Córdoba) were purified by means of conventional methods which include operations of mechanical separation and chemical treatments. The obtained materials were characterized by X-ray diffraction (XRD) and elemental chemical analysis. One of these materials was identified as a smectite type clay, whereas the other material showed characteristics of aluminous vermiculite type clay. The greater sodium cations content in the first clay than in the second clay is a determining factor to explain the difference on expansion capacity between these materials. The presence of small quantities (impurities) of quartz, illite, calcite, kaolinite and the possible presence of allophonic material reveal the origin and weathering environments of the primary minerals and suggest the formation of the characterized clays from the transformation of micaceus minerals.
