USE OF PHOSPHORIC ACID FOR REDUCING THE QUANTITY OF FREE DISPERSANT IN A PROCESS FOR CONCENTRATING CALCIUM CARBONATE IN WATER |
| abstract |
The invention consists in the use of phosphoric acid, in a process for concentrating an aqueous dispersion or suspension of calcium carbonate in the presence of at least one acrylic dispersant, as an agent for reducing the amount of free dispersant, ie the fraction of acrylic dispersant not adsorbed on the surface of the calcium carbonate particles and present in the aqueous phase. It also relates to dispersions and aqueous suspensions of calcium carbonate having a reduced amount of free dispersant. |
