  • Method for improving bulk density and flowability of calcined kaolin clay products
    Patent number: 5129953
    Abstract: The bulk handling characteristics of a calcined kaolin clay powder, including the bulk density and flowability, are significantly improved by forming an aqueous slurry of the calcined kaolin clay powder and spray drying the slurry.
    Type: Grant
    Filed: August 29, 1991
    Date of Patent: July 14, 1992
    Assignee: E.C.C. America, Inc.
    Inventors: Paul R. Suitch, Dursun E. Ince, Hilary Burgamy, A. Taylor Coppage, Tony May

  • Method for improving the rheology of calcined kaolin clay products
    Patent number: 5028268
    Abstract: The rheology of an aqueous slurry of a calcined kaolin clay powder is significantly improved by spray drying a slurry of the calcined kaolin clay powder, recovering the spray-dried material, and forming an aqueous slurry from said spray-dried material.
    Type: Grant

  • Method for improved flotation of discoloring impurities from kaolinite
    Patent number: 4997550
    Abstract: Flotation of a kaolin clay slurry to remove titanium-based impurities is improved by adding a biocide to the slurry prior to the flotation and effecting the flotation in the presence of the biocide. The addition of the biocide improves the efficacy of flotation and thereby increases the brightness of the clay. Preferred biocides are tetrahydrothiadiazine thiones, especially tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione.
