The product has a surface area in the range of 115-145 m/g as measured using the BET method. The heavy metal includes mercury and/or lead. Also disclosed is a method of producing the product and a method of adsorbing at least one heavy metal in a liquid using the product.

Product for metal adsorption

A bleaching clay product, a method of producing and a method of decolorizing an oil are disclosed. The bleaching clay product comprises attapulgite that has been thermally activated. The bleaching clay product may have a permeability in oil in the range of 0.04-3 darcy and may have a surface area of 45-140 m/g. The method of producing such bleaching clay product may comprise thermally activating a material that includes attapulgite by heating the material at a temperature in the range of 300 to 900° C. The method of decolorizing may include contacting for a contact time an oil with the bleaching clay product that comprises attapulgite that has been thermally activated, and separating the bleaching clay product from the oil to recover a decolorized oil that has a lower red color than the oil had prior to the contacting.

Thermally activated bleaching clay product for oil bleaching

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.

The invention is directed to a system which allows for the rapid application of a water immobilizing dispersion in sufficient quantities to increase the fire protective and wetting characteristics of water. This system also increases the evaporative cooling and quenching effects of water. The primary constituents of the composition of this system are water, purified Attapulgite clay, and an environmentally safe salt, e.g., magnesium sulfate.

Fire-barrier composition

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.

Purified attapulgite clay

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 said dispersant will not fully disperse other clay and mineral species, 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 with adsorbed dispersant is redispersed in water and retain thixotropic properties.

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.
