Abstract (en)
[origin: WO2007006368A2] Disclosed is a method for loading a pulp suspension (S) with calcium carbonate. According to said method, liquid calcium hydroxide is added as lime milk (7) during or before the dissolving process (1) carried out to form the pulp, for example. A chemical reaction in which finely distributed calcium carbonate is precipitated is triggered by introducing gaseous carbon dioxide (8) into the pulp suspension processed in said manner. The inventive method is particularly economical and effective by adding calcium oxide or calcium hydroxide early on.
