| 14 | Stabilized, high solids, low viscosity smectite slurries, and method of preparation | US619675 | 1996-03-29 | US5779785A | 1998-07-14 | James Payton; Nicholas Canaris; Jorge Miranda |
| An aqueous slurry of smectite clay of elevated solids content, comprising an aqueous solution or emulsion of at least 0.2% by weight of said slurry of a salt of a low molecular weight amine salt, in which is dispersed from about 10 to 47% by weight of the slurry, of a smectite clay. The amine salt is effective to prevent the smectite from swelling appreciably, whereby the slurry can be shipped and stored without creating a gelling problem. The inhibiting or suppressing effect of the amine salt on the swelling of the clay and on gelling of the slurry is reversible upon subsequent dilution with water, thereby facilitating use of the smectite in typical applications, e.g. as a retention aid in paper making, or as a viscosifier. | ||||||

| A stable high solids structured clay slurry is manufactured by a process which comprises the sequential steps of forming a high solids slurry by mixing a structured clay material with water in a first stage mixing step under conditions which promote particle to liquid contact and which substantially prevent interaction between the structured clay particles, terminating the first stage mixing and then, in a second stage mixing step, mixing the high solids slurry under conditions which are different from the first stage mixing conditions and which promote substantial interaction between the structured clay particles. | ||||||

| A high solids structured kaolin clay slurry having improved high shear rheology is manufactured by a process which comprises the sequential steps of forming an aqueous composition by mixing water and a lithium-based dispersant and then mixing structured kaolin clay particles with the aqueous composition to form the desired high solids slurry. | ||||||
| 17 | Method for preparing aqueous mineral suspensions | US725023 | 1991-07-03 | US5171725A | 1992-12-15 | Tommy A. Wright; Harvey M. Garrett; David F. Dwiggins |
| An improvement is disclosed applicable to systems where a mineral ore, such as a crude kaolin is introduced into a high shear, high energy mixing device with a suspending fluid and dispersing agents added to the same mixing device at controlled rates to produce a suspension with a solid content not more than 72% by weight. The process is applicable to systems where inorganic materials are suspended in a slurry, using water as the suspending fluid, in the presence of a dispersing agent, as for example in the processing of kaolin clay where the crude clay is formed into an aqueous suspension for the purpose of removing impurities and further processing. Heat is applied to the fluids in or before entering the mixing zone of the mixer, in sufficient quantity to raise the temperature of the suspension by at least 10.degree. C. This lowers the flow resistance of fluids in the mixing zone. In consequence less energy is required per unit of material processed, and more material may be processed in a given mixing unit. The heat may be added by several different methods, both directly and indirectly. | ||||||

| A bleached, dispersed, high solids slurry is produced from unprocessed crudes at low pH and with minimum work input, using polyacrylic acid as the dispersant. The process involves making the slurry at the highest solids possible without resorting to filtration or spray drying. | ||||||
| 19 | Method for controlling the viscosity of dispersed clay slurries | US852632 | 1977-11-18 | US4144084A | 1979-03-13 | William F. Abercrombie, Jr. |
| A method for controlling the viscosity of dispersed clay slurries is disclosed. In accordance with the invention the problem associated with shipping or storing clay slurries in tank cars or tanks, that is, significant increases in the viscosity of the slurry which often results in the formation of a gelled mass, is overcome by the addition of tartaric acid. The addition of the tartaric acid serves to control the viscosity of the clay slurry in a manner such that it remains at a substantially uniform and low level even when the slurry is shipped or stored over extended periods of time. The tartaric acid is added to the slurry in relatively small quantities, i.e., up to 5.0 pounds/ton clay and unexpectedly does not affect the properties or characteristics of the clay pigment or product. | ||||||
| 20 | Ceramic product and method of making same | US36991373 | 1973-06-14 | US3879211A | 1975-04-22 | KLOTZ JOSEPH M |
| A ceramic product is provided comprising, as initial ingredients, from 81 to 97 percent of red mud containing at least 40 percent iron expressed as Fe2O3, from 2 to 9 percent of sodium bentonite or from 2 to 25 percent of calcium bentonite, and from 0 to 10 percent of calcium sulfate, the product being vitrified by firing at a temperature in the range of 1950* to 2500* F. Also, a method of making a product of the above composition is provided wherein the ingredients mentioned above are blended together with sufficient water to provide a cohesive but formable mass. After forming into a desired shape, this mass is exposed to an atmosphere which is substantially saturated with water and then fired in the aforesaid temperature range for a period of time to cause the mass to be vitrified.
