Abstract: The present invention relates to an acid-stabilized calcium carbonate slurry having a pH of less than 7, preferably between about 6 and about 7, containing water, calcium carbonate, preferably precipitated calcium carbonate, and an acid-stabilizer of a water soluble calcium salt, a weak acid, a chelating agent, a weak acid capable of chelating calcium ion, or a mixture thereof. The acid-stabilizer is present in an amount sufficient to provide an aqueous calcium carbonate slurry having an increased calcium ion concentration and an acidic pH. In a typical acid-stabilized calcium carbonate slurry of the invention, the acid-stabilizer is present in an amount sufficient to provide a calcium ion concentration of about 1 millimolar to about 5 molar, preferably from about 1 to about 120 millimolar. The invention also relates to a method of making the acid-stabilized calcium carbonate slurry of the invention, to a method of forming a filled paper, that includes the step of adding the acid-stabilized calcium carbonate slurry of the invention to a papermaking pulp in a process for making acid paper, and to a filled paper produced according to the method of the invention

Abstract: Method and apparatus for concentrating slurries by removing liquid in a single effect unit maintained under vacuum to effect low temperature flashing of the liquid. The single effect unit comprises a single flash column with separate recirculation loops, one to preheat incoming slurry for concentration and a separate loop for withdrawal of concentrated slurry. Vapor from the flash column can be treated to separate liquid from other components in the vapor.
