A process for the production of precipitated silica comprising the steps of: - reacting at least one silicate with at least one acidifying agent by: (i) providing at least a portion of the total amount of the silicate involved in the reaction and an electrolyte in a vessel, the concentration of silicate (expressed as SiO 2) initially present in said vessel being less than 100 g/l and, preferably, the concentration of electrolyte initially present in said vessel being less than 19 g/l; (ii) adding an amount of an acidifying agent to said vessel to obtain a pH value for the reaction medium of at least 7.0, in particular of between 7.0 and 8.5; (iii) further adding an acidifying agent and, if appropriate, simultaneously the remaining amount of silicate to the reaction medium to obtain a silica suspension; - submitting said silica suspension to filtration to provide a filter cake; - submitting said filter cake to a liquefaction step, optionally comprising the addition of an aluminum compound, to obtain a suspension of precipitated silica; and - optionally, drying the precipitated silica obtained after the liquefaction step; wherein at least one polycarboxylic acid is added to the filter cake during or after the liquefaction step, wherein said polycarboxylic acid is selected from the group consisting of the linear or branched, saturated or unsaturated, aliphatic polycarboxylic acids having from 5 to 20 carbon atoms and the aromatic polycarboxylic acids with the proviso that, when the liquefaction step comprises the addition of an aluminium compound, said polycarboxylic acid is not selected from the group consisting of any methylglutaric acid and of the mixtures of polycarboxylic acids. - reacting at least one silicate with at least one acidifying agent by: (i) providing at least a portion of the total amount of the silicate involved in the reaction and an electrolyte in a vessel, the concentration of silicate (expressed as SiO 2) initially present in said vessel being less than 100 g/l and, preferably, the concentration of electrolyte initially present in said vessel being less than 19 g/l; (ii) adding an amount of an acidifying agent to said vessel to obtain a pH value for the reaction medium of at least 7.0, in particular of between 7.0 and 8.5; (iii) further adding an acidifying agent and, if appropriate, simultaneously the remaining amount of silicate to the reaction medium to obtain a silica suspension; (i) providing at least a portion of the total amount of the silicate involved in the reaction and an electrolyte in a vessel, the concentration of silicate (expressed as SiO 2) initially present in said vessel being less than 100 g/l and, preferably, the concentration of electrolyte initially present in said vessel being less than 19 g/l; (ii) adding an amount of an acidifying agent to said vessel to obtain a pH value for the reaction medium of at least 7.0, in particular of between 7.0 and 8.5; (iii) further adding an acidifying agent and, if appropriate, simultaneously the remaining amount of silicate to the reaction medium to obtain a silica suspension; - submitting said silica suspension to filtration to provide a filter cake; - submitting said filter cake to a liquefaction step, optionally comprising the addition of an aluminum compound, to obtain a suspension of precipitated silica; and - optionally, drying the precipitated silica obtained after the liquefaction step; wherein at least one polycarboxylic acid is added to the filter cake during or after the liquefaction step, wherein said polycarboxylic acid is selected from the group consisting of the linear or branched, saturated or unsaturated, aliphatic polycarboxylic acids having from 5 to 20 carbon atoms and the aromatic polycarboxylic acids with the proviso that, when the liquefaction step comprises the addition of an aluminium compound, said polycarboxylic acid is not selected from the group consisting of any methylglutaric acid and of the mixtures of polycarboxylic acids.
