A process for preparing precipitated silica in which: (i) an stock having a concentration of alkali metal M silicate less than 20 g/L is formed; (ii) acid is added to said initial stock, until at least 50% of the amount of M2O is neutralized; (iii) silicate and acid are simultaneously added, such that the degree of consolidation is greater than 4 and at most 100; and (v) acid is added until a pH value of between 2.5 and 5.3 is obtained, wherein the acid used in at least one of the process steps is a concentrated acid.
