Bentonite quality, and, consequently, its applications, depend on whether it contains any of these other minerals. Its density when dry varies depending on the quality, and may range from 2.2 to 2.8 g/cm 3. Bentonite apparent density, when quarried and piled under natural moisture conditions, ranges from 1.5 to 1.8 g/cm 3.
