Bentonites refer to the class of argilliferous folded silicate rocks, which as a whole have such common characteristics, as dispersion (fragmentation), colloidal properties, propensity to wetness, and adsorption properties. The importance of this paper, as it follows from the conclusion, is connected with the study of synthesizing of magnetic clay composites which have high adsorption capacity, as well as with systematization of their properties. Bentonite magnetic composites are among those which can be stabilized using sodium alginate. Magnetic composites synthesized on the basis of bentonite showed the proportion of magnetite corresponding to the proportion of Fe in the composition of the initial clays. Sodium alginate-based stabilization method is an effective one for bentonite magnetic composites.
