    Publication number: 20070181275
    Abstract: A process for the production of paper by introducing a suspension of ultrafine calcium carbonate particles to a fiber-containing suspension. A method for improving the dewatering of a fiber-containing suspension. Use of a calcium carbonate suspension comprising ultrafine particles of calcium carbonate as a substitute for colloidal silica as a dewatering agent in the formation of paper from a fiber-containing suspension. At least one ionic polymer is introduced in the fiber-containing suspension.
