Use of phosphoric acid to reduce the quantity of free dispersing agent in a method for concentrating calcium carbonate in water |
abstract |
The invention consists of the use of phosphoric acid, in a method for concentrating an aqueous dispersion or suspension of calcium carbonate in the presence of at least one acrylic dispersing agent, as an agent for reducing the quantity of free dispersing agent, i.e. the fraction of acrylic dispersing agent not adsorbed onto the surface of the particles of the calcium carbonate and present in the aqueous phase. It also pertains to the aqueous dispersions or suspensions of calcium carbonate, exhibiting a reduced quantity of free dispersing agent. |
