Abstract
A particulate absorbent material is constituted by discrete clay granules and paper granules, and usually exhibits a bulk density of about 10 lbs/ft.sup.3 to about 30 lbs/ft.sup.3. The weight ratio of paper granules-to-clay granules is about 0.09 to about 9. The particle size distribution for the clay granules is relatively wider than for the paper granules.
