Use of phosphoric acid to reduce the quantity of free dispersing agent in a method for concentrating calcium carbonate 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 one or more acrylic dispersant, Lt; RTI ID = 0.0 > non-adsorbed < / RTI > in the aqueous phase. The present invention also relates to aqueous dispersions or suspensions of calcium carbonate which exhibit reduced amounts of free dispersing agents. |
