Use of phosphoric acid to reduce the amount of free dispersant in a method for concentrating calcium carbonate dissolved in water |
| abstract |
The present invention consists in the use of phosphoric acid as a reagent for reducing the amount of free dispersant in a method of concentrating an aqueous dispersion or suspension of calcium carbonate in the presence of at least one acrylic dispersant, wherein the free dispersant is a calcium carbonate particle surface. It is part of the acrylic dispersant present in the aqueous phase without being adsorbed on. The invention also relates to an aqueous dispersion or suspension of calcium carbonate which exhibits a reduced amount of free dispersant. |
