Process for preparing precipitated silica, of the type comprising the precipitation reaction between a silicate and at least one acid, whereby a suspension of precipitated silica is obtained, followed by the separation and drying of this suspension, wherein: - the precipitation reaction is carried out in the following way: (i) an initial stock comprising a silicate and an electrolyte is formed, the concentration of silicate expressed as SiO 2 in said initial stock being less than 100 g/l and, preferably, the concentration of electrolyte in said initial stock being less than 19 g/l, (ii) an acid is added to said stock until a pH value of the reaction medium of at least 7.0, in particular between 7 and 8.5, is obtained, (iii) an acid and a silicate are added simultaneously to the reaction medium, (iv) an acid is added to the reaction medium, in particular until a pH value of the reaction medium of between 3.0 and 6.5 is obtained, - a suspension, preferably having a solids content of at most 24% by weight, is dried, process wherein the acid used in steps (iii) and (iv) is a concentrated acid chosen from sulfuric acid having a concentration of at least 80% by weight, in particular of at least 90% by weight, acetic acid having a concentration of at least 90% by weight, formic acid having a concentration of at least 90% by weight, nitric acid having a concentration of at least 60% by weight, phosphoric acid having a concentration of at least 75% by weight, or hydrochloric acid having a concentration of at least 30% by weight, and characterized in that, in step (ii), the acid used after reaching the gel point in the reaction medium is a concentrated acid, preferably chosen from sulfuric acid having a concentration of at least 80% by weight, in particular of at least 90% by weight, acetic acid having a concentration of at least 90% by weight, formic acid having a concentration of at least 90% by weight, nitric acid having a concentration of at least 60% by weight, phosphoric acid having a concentration of at least 75% by weight, or hydrochloric acid having a concentration of at least 30% by weight. - the precipitation reaction is carried out in the following way: (i) an initial stock comprising a silicate and an electrolyte is formed, the concentration of silicate expressed as SiO 2 in said initial stock being less than 100 g/l and, preferably, the concentration of electrolyte in said initial stock being less than 19 g/l, (ii) an acid is added to said stock until a pH value of the reaction medium of at least 7.0, in particular between 7 and 8.5, is obtained, (iii) an acid and a silicate are added simultaneously to the reaction medium, (iv) an acid is added to the reaction medium, in particular until a pH value of the reaction medium of between 3.0 and 6.5 is obtained, (i) an initial stock comprising a silicate and an electrolyte is formed, the concentration of silicate expressed as SiO 2 in said initial stock being less than 100 g/l and, preferably, the concentration of electrolyte in said initial stock being less than 19 g/l, (ii) an acid is added to said stock until a pH value of the reaction medium of at least 7.0, in particular between 7 and 8.5, is obtained, (iii) an acid and a silicate are added simultaneously to the reaction medium, (iv) an acid is added to the reaction medium, in particular until a pH value of the reaction medium of between 3.0 and 6.5 is obtained, - a suspension, preferably having a solids content of at most 24% by weight, is dried,
