  • Granulated kaolin compositions and processes for their production
    Patent number: 8388750
    Abstract: Disclosed herein are granulated kaolin compositions exhibiting at least one of improved material handling properties, low dusting during transit, easy make-down into mineral-water slurries, and requiring less energy to produce than spray dried kaolin products. The granulated kaolin compositions may, in one embodiment, be characterized by a moisture content ranging from about 12% to about 23% by weight relative to the total weight of the composition. In another embodiment, the granulated kaolin compositions may have an average granule size of greater than about 10 mesh. Also disclosed herein are granulated kaolin compositions having a moisture content ranging from about 12% to about 23% by weight relative to the total weight of the composition, wherein the composition is friable when subjected to a shear force.

  • Treatment of Mineral Processing Waste Waters Using Disc-Nozzle Centrifuges
    Publication number: 20090208750
    Abstract: Disclosed herein are methods for treating waste waters resulting from mineral processing, including waste water from flushing high intensity magnetic matrices during kaolin processing, by sedimenting the waste water and then subjecting the waste water supernatant from sedimentation to processing in a disc-nozzle centrifuge. Also disclosed herein are methods for further processing of the products of the disc-nozzle centrifugation.
