  • Patent number: 11708307
    Abstract: A composition comprises at least one form of attapulgite present in a solid weight fraction amount ranging from 0.25% to 5%; kaolin present in a solid weight fraction amount ranging from 17% to 50%; and optionally Ball Clay in a solid weight fraction amount ranging from 0% to 25%. Although makeable by other processes, in some embodiments, the composition is makeable by mixing component ingredients. Although usable for other purposes, in some embodiments, the composition is used to make ceramic pieces, e.g., via casting, pressing, jiggering or jollying, especially when the slip has solids, chemistry and viscosity suitable for shaping before drying, sintering, and optionally finishing.

  • Patent number: 6444601
    Abstract: A method for producing an Attapulgite clay (Fuller's Earth) that significantly removes other types of clays and minerals, resulting in improved performance. A unique dispersant is used that will fully disperse the individual Attapulgite particles in water such that the particles remain in suspension, and allow the non-Attapulgite clay particles to be liberated, which then can be easily separated through various techniques. The Attapulgite clay may be recovered from the dispersion and dried in such a manner to produce a finely sized powder from ore, without the need for any grinding or milling operation. The dried Attapulgite clay has a free moisture content of 2-3%. The dried Attapulgite clay with adsorbed dispersant is redispersed in water and retains thixotropic properties.

  • Patent number: 5749936
    Abstract: An improved continuous process for producing granular fertilizer and/or soil amendments resulting in a high quality granular product. A slurry of clay in water with a dispersant is prepared using intensive mixing. Dry components are intimately mixed with the slurry in a mixer. The mixture is fed into a granulator to produce granules within a desired range of granule sizes. The granules are dried in a dryer and screened to remove any granules of an undesired size. The undesired granules are recycled.
