As an admixtures itcontaines quartz, illite and other minerals. The admixtures are inhomogeneously distributed in various particle sizefractions. The subject of this research is concentration and separation of existing admixtures from bentonite clay(–0.063 mm), a commercial product of Bentomak. Wet sieve analysis and elutriation were applied as separationmethods. In order to define the efficiency of the methods, a complex examination for characterization of the fractionswas realized. Simultaneous review of the results of XRD, microscopic examinations and chemical analysis indicatesthat in the finest fraction (–0.032 mm) the concentration of the admixures is smaller for 80% than in the other fractions.
