Preparation of a masterbatch of diene elastomer and silica including preparing at least one silica dispersion in water; bringing into contact and mixing an elastomer latex and the aqueous silica dispersion in the presence of a metal salt having an at least divalent metal element, in order to obtain a coagulum; and recovering the coagulum and drying same in order to obtain the masterbatch. The metal cation molar ration, defined as the number of moles of metal cations of the metal salt per BET unit area of the silica, is between 9.375*10−7 and 1.875*10−5 mol/m2.
