A method of recovering a mineral product from carpet by preparing a feed of carpet pieces; thermally separating organic components from mineral components in the carpet by heating the carpet pieces to a particle bed temperature in the range of 600 C. to 1000 C. , wherein the mineral component is oxidized to form a mineral oxide; slurrying the mineral oxide with water to produce 15 to 35% solids slurry within a period of approximately 30 minutes to 24 hours, whereby the mineral oxide forms a mineral hydroxide; stabilizing the pH of the slurry in the range between 6 and 10 by carbonation, resulting in a slurry containing mineral carbonates.

US Classification:
210388
Abstract:
An apparatus is disclosed for filtering slurries of minerals or other fine particles. The apparatus includes a filter plate having an interior porous support layer and a microporous metal filtration layer overlying the support layer, the pore sizes in the filtration layer preferably being in the range of from about 0. 2 to 3 microns. The side of the filtration layer non-adjacent the support layer constitutes a filter surface for the mineral.

Abstract:
In the process for beneficiating a crude kaolin by the method which includes a wet classification step to provide a classified kaolin fraction having a PSD such that at least 50% by weight thereof are of less than 1/2. mu. m ESD and substantially 100% by weight are of less than 10. mu. m ESD; and one or more steps wherein an aqueous slurry of the classified kaolin is at least partially dewatered by filtration; the improvement which comprises effecting at least one of said one or more filtration steps, by flowing said aqueous kaolin slurry through a ceramic filter plate which is characterized by a porous support layer and an overlying porous filtration layer, the ratio between the respective mean pore sizes of the filtration layer material and the base layer material being between about 2 and 50; the pore size in said filtration layer being in the range of from about 1 to 3. mu. m, and the pore size in the base layer being in the range of from about 4 to 50. mu. m; and said flow through said filter plate being from said filter layer toward said base layer, and being effected by establishing a fluid pressure differential across the said filter plate.
The low shear, slurry viscosity of a kaolinitic clay that is contaminated with one or more forms of expanding clay is reduced by mixing the clay with a source of cationic potassium and then heating the potassium-treated clay to a temperature of at least about 100. degree. C.

International Classification:
C04B 1410
US Classification:
106486
Abstract:
A method which enables economical and highly effective preparation of refined kaolin clay products having preselected particle size distributions and brightnesses, by means of separate, efficient and economical processing of at least two crude components. A fine particle size kaolin crude having a PSD such that at least 85% by weight of the particles are of less than 2 micrometers ESD is wet beneficiated to provide a first product component having a PSD of at least 95% by weight less than 2 micrometers and a brightness of at least 89 on the G. E. scale. This wet beneficiation is conducted without use of a froth flotation step. A coarse particle size kaolin crude having a PSD such that less than 85% by weight of particles are of less than 2 micrometers ESD, is separately wet beneficiated to produce a second product component having a PSD of no more than 85% by weight less than 2 micrometers and a brightness of at least 89 on the G. E. scale. This last wet beneficiation is, however, conducted with use of a conventional froth flotation step. The first and second product components are then blended in proportions to produce the desired refined kaolin clay product having a preselected PSD and brightness.

International Classification:
B03B 104 B03B 700 B03C 102
US Classification:
209164
Abstract:
A method for beneficiating a kaolin clay which includes quantities of smectite contaminants to reduce the low and high shear viscosities of high solids aqueous slurries of the kaolin. The smectite is converted into a pillared clay by intercalating it with a polymeric cationic hydroxy metal complex wherein the metal is ferromagnetic or diamagnetic. The kaolin and pillared smectite is then subjected as an aqueous slurry to high intensity magnetic separation, to separate the pillared smectite, and the beneficiated kaolin is recovered as product.

International Classification:
C04B 3302
US Classification:
501145
Abstract:
A method for producing calcined kaolin pigments of high opacifying properties and low abrasion. A kaolin crude is selected having a G. E. brightness in the range of 70 to 80, a titania content of 2. 0 to 3. 0% by weight, less than 2% iron expressed as Fe. sub. 2 O. sub. 3, and a particle size distribution such that at least 88% by weight of the particles of said crude are of less than 2. mu. m E. S. D. The crude is blunged with water, and the resultant slurry degritted to form an aqueous slurry having at least 65% by weight solids. The slurry is centrifuged and a fraction recovered having over 65% solids, and in which at least 92% by weight of the particles are of less than 2. mu. m. The recovered fraction is dried to less than 1% moisture, and pulverized to break up agglomerates. The pulverized fraction is then calcined by heating same to 1450. degree. to 1600. degree. F.
