Abstract
A process for the manufacture of adsorbent clay mineral particles comprises first selecting clay mineral particles smaller than 2 millimeter in size, drying the clay mineral particles to a moisture content not exceeding 15% by weight and mixing the dried particles with from 0.2% to 5% by weight of a water dispersible colloid in water to form a mixture having a final moisture content not exceeding 15% by weight. The mixture is compacted in a press and the compacted material broken into masses of particles larger in size than the selected clay mineral particles and in the 710 micron to 4 millimeter size range. The product of the process is useful for example as a litter.
