  • 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.

  • Chemically aggregated mineral pigments
    Patent number: 5068276
    Abstract: A method is described for forming bulked aggregates of mineral particles such as kaolins. An aqueous slurry of the mineral is treated with a source of a multi-valent cation to floc the mineral, polyacrylic is added and the slurry is then neutralized with a base to an alkaline pH. This treatment causes the polyacrylic acid to undergo cross-linking with the cations to form the polyacrylate which precipitates in situ on the mineral floc and preserves and retains the bulked, porous floc structure, whereby pore radius and volume of the treated mineral are increased. The products are useful as fillers or as coating pigments in paper manufacture.
